1. Accessing Foreman

After Foreman has been installed and configured, use the Foreman web UI interface to log in to Foreman for further configuration.

1.1. Logging in to Foreman

Use the web user interface to log in to Foreman for further configuration.

Procedure

  1. Access Foreman server using a web browser pointed to the fully qualified domain name:

    https://foreman.example.com/

  2. Enter the user name and password created during the configuration process. If a user was not created during the configuration process, the default user name is admin. If you have problems logging in, you can reset the password. For more information, see Resetting the Administrative User Password.

1.2. Using FreeIPA credentials to log in to the Foreman Hammer CLI

This section describes how to log in to your Foreman Hammer CLI with your FreeIPA (IdM) login and password.

Prerequisites

  • You have enrolled your Foreman server into FreeIPA and configured it to use FreeIPA for authentication. More specifically, you have enabled access both to the Foreman web UI and the Foreman API. For more information, see Using FreeIPA in Installing Foreman 3.5 Server on RHEL/CentOS.

  • The host on which you run this procedure is configured to use FreeIPA credentials to log users in to your Foreman Hammer CLI. For more information, see Configuring the Hammer CLI to Use FreeIPA User Authentication in Installing Foreman 3.5 Server on RHEL/CentOS.

  • The host is an FreeIPA client.

  • An FreeIPA server is running and reachable by the host.

Procedure

  1. Obtain a Kerberos ticket-granting ticket (TGT) on behalf of a Foreman user:

    $ kinit idm_user
    Warning

    If, when you were setting FreeIPA to be the authentication provider, you enabled access to both the Foreman API and the Foreman web UI, an attacker can now obtain an API session after the user receives the Kerberos TGT. The attack is possible even if the user did not previously enter the Foreman login credentials anywhere, for example in the browser.

  2. If automatic negotiate authentication is not enabled, use the TGT to authenticate to Hammer manually:

    $ hammer auth login negotiate

  3. Optional: Destroy all cached Kerberos tickets in the collection:

    $ kdestroy -A

You are still logged in, even after destroying the Kerberos ticket.

Verification

  • Use any hammer command to ensure that the system does not ask you to authenticate again:

    $ hammer host list
Note

To log out of Hammer, enter: hammer auth logout.

1.3. Using FreeIPA credentials to log in to the Foreman web UI with a Firefox browser

This section describes how to use the Firefox browser to log in to your Foreman web UI with your FreeIPA (IdM) login and password.

Prerequisites

  • You have enrolled your Foreman server into FreeIPA and configured the server to use FreeIPA for authentication. For more information, see Using FreeIPA in Installing Foreman 3.5 Server on RHEL/CentOS.

  • The host on which you are using a Firefox browser to log in to the Foreman web UI is an FreeIPA client.

  • You have a valid FreeIPA login and password.

  • Foreman community recommends using the latest stable Firefox browser.

  • Your Firefox browser is configured for Single Sign-On (SSO).

  • An FreeIPA server is running and reachable by the host.

Procedure

  1. Obtain the Kerberos ticket granting ticket (TGT) for yourself using your FreeIPA credentials:

    $ kinit idm_user
Password for idm_user@EXAMPLE.COM:

  2. In your browser address bar, enter the URL of your Foreman server.

    You are logged in automatically.

Note

Alternatively, you can skip the first two steps and enter your login and password in the fields displayed on the Foreman web UI. This is also the only option if the host from which you are accessing the Foreman web UI is not an FreeIPA client.

1.4. Using FreeIPA credentials to log in to the Foreman web UI with a Chrome browser

This section describes how to use a Chrome browser to log in to your Foreman web UI with your FreeIPA login and password.

Prerequisites

Procedure

  1. Enable the Chrome browser to use Kerberos authentication:

    $ google-chrome --auth-server-whitelist="*.example.com" --auth-negotiate-delegate-whitelist=”*.example.com"
    Note

    Instead of allowlisting the whole domain, you can also allowlist a specific Foreman server.

  2. Obtain the Kerberos ticket-granting ticket (TGT) for yourself using your FreeIPA credentials:

    $ kinit idm_user
Password for idm_user@_EXAMPLE.COM:

  3. In your browser address bar, enter the URL of your Foreman server.

    You are logged in automatically.

Note

Alternatively, you can skip the first three steps and enter your login and password in the fields displayed on the Foreman web UI. This is also the only option if the host from which you are accessing the Foreman web UI is not an FreeIPA client.

Use the navigation tabs to browse the Foreman web UI.

$ ansible-doc theforeman.foreman.activation_key

4. Managing Users and Roles

A User defines a set of details for individuals using the system. Users can be associated with organizations and environments, so that when they create new entities, the default settings are automatically used. Users can also have one or more roles attached, which grants them rights to view and manage organizations and environments. See Managing Users for more information on working with users.

You can manage permissions of several users at once by organizing them into user groups. User groups themselves can be further grouped to create a hierarchy of permissions. For more information on creating user groups, see Creating and Managing User Groups.

Roles define a set of permissions and access levels. Each role contains one on more permission filters that specify the actions allowed for the role. Actions are grouped according to the Resource type. Once a role has been created, users and user groups can be associated with that role. This way, you can assign the same set of permissions to large groups of users. Foreman provides a set of predefined roles and also enables creating custom roles and permission filters as described in Creating and Managing Roles.

4.1. Managing Users

As an administrator, you can create, modify and remove Foreman users. You can also configure access permissions for a user or a group of users by assigning them different roles.

4.1.1. Creating a User

Use this procedure to create a user. To use the CLI instead of the Foreman web UI, see the CLI procedure.

Procedure

  1. In the Foreman web UI, navigate to Administer > Users.

  2. Click Create User.

  3. In the Login field, enter a username for the user.

  4. In the Firstname and Lastname fields, enter the real first name and last name of the user.

  5. In the Mail field, enter the user’s email address.

  6. In the Description field, add a description of the new user.

  7. Select a specific language for the user from the Language list.

  8. Select a timezone for the user from the Timezone list.

    By default, Foreman server uses the language and timezone settings of the user’s browser.

  9. Set a password for the user:

    1. From the Authorized by list, select the source by which the user is authenticated.

      • INTERNAL: to enable the user to be managed inside Foreman server.

      • EXTERNAL: to configure external authentication as described in Configuring External Authentication in Installing Foreman 3.5 Server on RHEL/CentOS.

    2. Enter an initial password for the user in the Password field and the Verify field.

  10. Click Submit to create the user.

CLI procedure

  • To create a user, enter the following command:

    # hammer user create \
--auth-source-id My_Authentication_Source \
--login My_User_Name \
--mail My_User_Mail \
--organization-ids My_Organization_ID_1,My_Organization_ID_2 \
--password My_User_Password

    The --auth-source-id 1 setting means that the user is authenticated internally, you can specify an external authentication source as an alternative. Add the --admin option to grant administrator privileges to the user. Specifying organization IDs is not required, you can modify the user details later using the update subcommand.

For more information about user related subcommands, enter hammer user --help.

4.1.2. Assigning Roles to a User

4.7.1. Creating a Granular Permission Filter

Use this procedure to create a granular filter. To use the CLI instead of the Foreman web UI, see the CLI procedure.

Foreman does not apply search conditions to create actions. For example, limiting the create_locations action with name = "Default Location" expression in the search field does not prevent the user from assigning a custom name to the newly created location.

Procedure

Specify a query in the Search field on the Edit Filter page. Deselect the Unlimited checkbox for the field to be active. Queries have the following form:

field_name operator value

  • field_name marks the field to be queried. The range of available field names depends on the resource type. For example, the Partition Table resource type offers family, layout, and name as query parameters.

  • operator specifies the type of comparison between field_name and value. See Supported Operators for Granular Search for an overview of applicable operators.

  • value is the value used for filtering. This can be for example a name of an organization. Two types of wildcard characters are supported: underscore (_) provides single character replacement, while percent sign (%) replaces zero or more characters.

For most resource types, the Search field provides a drop-down list suggesting the available parameters. This list appears after placing the cursor in the search field. For many resource types, you can combine queries using logical operators such as and, not and has operators.

CLI procedure

  • To create a granular filter, enter the hammer filter create command with the --search option to limit permission filters, for example:

    # hammer filter create \
--permission-ids 91 \
--search "name ~ ccv*" \
--role qa-user

This command adds to the qa-user role a permission to view, create, edit, and destroy Content Views that only applies to Content Views with name starting with ccv.

4.7.2. Examples of Using Granular Permission Filters

As an administrator, you can allow selected users to make changes in a certain part of the environment path. The following filter allows you to work with content while it is in the development stage of the application life cycle, but the content becomes inaccessible once is pushed to production.

Applying Permissions for the Host Resource Type

The following query applies any permissions specified for the Host resource type only to hosts in the group named host-editors.

hostgroup = host-editors

The following query returns records where the name matches XXXX, Yyyy, or zzzz example strings:

name ^ (XXXX, Yyyy, zzzz)

You can also limit permissions to a selected environment. To do so, specify the environment name in the Search field, for example:

Dev

You can limit user permissions to a certain organization or location with the use of the granular permission filter in the Search field. However, some resource types provide a GUI alternative, an Override checkbox that provides the Locations and Organizations tabs. On these tabs, you can select from the list of available organizations and locations. For more information, see Creating an Organization Specific Manager Role.

Creating an Organization Specific Manager Role

Use the Foreman web UI to create an administrative role restricted to a single organization named org-1.

Procedure

  1. In the Foreman web UI, navigate to Administer > Roles.

  2. Clone the existing Organization admin role. Select Clone from the drop-down list next to the Filters button. You are then prompted to insert a name for the cloned role, for example org-1 admin.

  3. Click the desired locations and organizations to associate them with the role.

  4. Click Submit to create the role.

  5. Click org-1 admin, and click Filters to view all associated filters. The default filters work for most use cases. However, you can optionally click Edit to change the properties for each filter. For some filters, you can enable the Override option if you want the role to be able to access resources in additional locations and organizations. For example, by selecting the Domain resource type, the Override option, and then additional locations and organizations using the Locations and Organizations tabs, you allow this role to access domains in the additional locations and organizations that is not associated with this role. You can also click New filter to associate new filters with this role.

5. Configuring Email Notifications

Email notifications are created by Foreman server periodically or after completion of certain events. The periodic notifications can be sent daily, weekly or monthly.

For an overview of available notification types, see Email Notification Types.

Users do not receive any email notifications by default. An administrator can configure users to receive notifications based on criteria such as the type of notification, and frequency.

Important

Foreman server does not enable outgoing emails by default, therefore you must review your email configuration. For more information, see Configuring Foreman server for Outgoing Emails in Installing Foreman 3.5 Server on RHEL/CentOS.

5.1. Email Notification Types

Foreman can create the following email notifications:

  • Audit summary: A summary of all activity audited by Foreman server.

  • Host built: A notification sent when a host is built.

  • Host errata advisory: A summary of applicable and installable errata for hosts managed by the user.

  • Compliance policy summary: A summary of OpenSCAP policy reports and their results.

  • Promote errata: A notification sent only after a Content View promotion. It contains a summary of errata applicable and installable to hosts registered to the promoted Content View. This allows a user to monitor what updates have been applied to which hosts.

  • Sync errata: A notification sent only after synchronizing a repository. It contains a summary of new errata introduced by the synchronization.

For a complete list of email notification types, navigate to Administer > Users in the Foreman web UI, click the Username of the required user, and select the Email Preferences tab.

5.2. Configuring Email Notification Preferences

You can configure Foreman to send email messages to individual users registered to Foreman. Foreman sends the email to the email address that has been added to the account, if present. Users can edit the email address by clicking on their name in the top-right of the Foreman web UI and selecting My account.

Configure email notifications for a user from the Foreman web UI.

Note

If you want to send email notifications to a group email address instead of an individual email address, create a user account with the group email address and minimal Foreman permissions, then subscribe the user account to the desired notification types.
Prerequisites

  • The user you are configuring to receive email notifications has a role with this permission: view_mail_notifications.

Procedure

  1. In the Foreman web UI, navigate to Administer > Users.

  2. Click the Username of the user you want to edit.

  3. On the User tab, verify the value of the Mail field. Email notifications will be sent to the address in this field.

  4. On the Email Preferences tab, select Mail Enabled.

  5. Select the notifications you want the user to receive using the drop-down menus next to the notification types.

    Note

    The Audit Summary notification can be filtered by entering the required query in the Mail Query text box.

  6. Click Submit.

    The user will start receiving the notification emails.

5.3. Testing Email Delivery

To verify the delivery of emails, send a test email to a user. If the email gets delivered, the settings are correct.

Procedure

  1. In the Foreman web UI, navigate to Administer > Users.

  2. Click on the username.

  3. On the Email Preferences tab, click Test email.

    A test email message is sent immediately to the user’s email address.

If the email is delivered, the verification is complete. Otherwise, you must perform the following diagnostic steps:

  1. Verify the user’s email address.

  2. Verify Foreman server’s email configuration.

  3. Examine firewall and mail server logs.

  4. If your Foreman server uses the Postfix service for email delivery, the test email might be held in the queue. To verify, enter the mailq command to list the current mail queue. If the test email is held in the queue, mailq displays the following message:

    postqueue: warning: Mail system is down -- accessing queue directly
-Queue ID-  --Size-- ----Arrival Time---- -Sender/Recipient-------
BE68482A783    1922 Thu Oct  3 05:13:36  foreman-noreply@example.com

    To fix the problem, start the Postfix service on your Foreman server:

    # systemctl start postfix

5.4. Testing Email Notifications

To verify that users are correctly subscribed to notifications, trigger the notifications manually.

Procedure

  • To trigger the notifications, execute the following command:

    # foreman-rake reports:_My_Frequency_

    Replace My_Frequency with one of the following:

  • daily

  • weekly

  • monthly

This triggers all notifications scheduled for the specified frequency for all the subscribed users. If every subscribed user receives the notifications, the verification succeeds.

Note

Sending manually triggered notifications to individual users is currently not supported.

5.5. Changing Email Notification Settings for a Host

Foreman can send event notifications for a host to the host’s registered owner. You can configure Foreman to send email notifications either to an individual user or a user group. When set to a user group, all group members who are subscribed to the email type receive a message.

Receiving email notifications for a host can be useful, but also overwhelming if you are expecting to receive frequent errors, for example, because of a known issue or error you are working around.

Procedure

  1. In the Foreman web UI, navigate to Hosts > All Hosts, locate the host that you want to view, and click Edit in the Actions column.

  2. Go to the Additional Information tab. If the checkbox Include this host within Foreman reporting is checked, then the email notifications are enabled on that host.

  3. Optional: Toggle the checkbox to enable or disable the email notifications.

    Note

    If you want to receive email notifications, ensure that you have an email address set in your user settings.

6. Managing Security Compliance

Security compliance management is the ongoing process of defining security policies, auditing systems for compliance with those policies, and resolving instances of non-compliance. Any non-compliance is managed according to the organization’s configuration management policies. Security policies range in scope from host-specific to industry-wide, therefore, flexibility in their definition is required.

With Foreman, you can schedule compliance auditing and reporting on all registered hosts.

6.1. Security Content Automation Protocol

Foreman uses the Security Content Automation Protocol (SCAP) standard to define security policies.

SCAP is a framework of several specifications based on XML, such as checklists described in the Extensible Checklist Configuration Description Format (XCCDF) and vulnerabilities described in the Open Vulnerability and Assessment Language (OVAL). These specifications are encapsulated as data stream files.

Checklist items in XCCDF, also known as rules, express the desired configuration of a system item. For example, a rule may specify that no one can log in to a host over SSH using the root user account. Rules can be grouped into one or more XCCDF profiles, which allows multiple profiles to share a rule.

The OpenSCAP scanner tool evaluates system items on a host against the rules and generates a report in the Asset Reporting Format (ARF), which is then returned to Foreman for monitoring and analysis.

6.2. SCAP Content in Foreman

SCAP content is a SCAP data-stream file that contains implementation of compliance, configuration, or security baselines. A single data stream usually includes multiple XCCDF profiles. An XCCDF profile defines an industry standard or custom security standard against which you can evaluate compliance of host configuration in Foreman, such as Protection Profile for General Purpose Operating Systems (OSPP), Health Insurance Portability and Accountability Act (HIPAA), and PCI-DSS v3.2.1 Control Baseline for Enterprise Linux 9. You can adapt existing XCCDF profiles according to your requirements using tailoring files.

In Foreman, you use an XCCDF profile from SCAP content and, eventually, a tailoring file, to define a compliance policy. Foreman includes default SCAP contents from SCAP Security Guide provided by the OpenSCAP project.

For more information on how to download, deploy, modify, and create your own content, see:

6.2.1. Supported SCAP Versions

Foreman supports content of SCAP versions 1.2 and 1.3.

6.3. Compliance Policy Deployment Options

You can use one of the following methods to deploy compliance policies:

Ansible deployment

You use an Ansible role to configure hosts for compliance scans.

Puppet deployment

You use a Puppet class and the Puppet agent to configure hosts for compliance scans.

Manual deployment

You manually configure hosts for compliance scans.

6.4. Installing the OpenSCAP Plug-in

You can install and enable the OpenSCAP plug-in to generate SCAP compliance reports. The OpenSCAP plug-in consists of the OpenSCAP Foreman plug-in, the OpenSCAP Hammer CLI plug-in, the OpenSCAP Smart Proxy plug-in, and the module for Puppet policy deployment.

Procedure

  1. Install the OpenSCAP plug-in on your Foreman server:

    # foreman-installer \

    # hammer scap-content bulk-upload --type directory \
--directory /usr/share/xml/scap/my_content/ \
--location "My_Location" \
--organization "My_Organization"
Verification

6.7.4. Tailoring XCCDF Profiles

You can customize existing XCCDF profiles using tailoring files without editing the original SCAP content. A single tailoring file can contain customizations of multiple XCCDF profiles.

You can create a tailoring file using the SCAP Workbench tool. For more information on using the SCAP Workbench tool, see Customizing SCAP Security Guide for your use case.

Then you can assign a tailoring file to a compliance policy to customize an XCCDF profile in the policy.

6.7.5. Uploading a Tailoring File

After uploading a tailoring file, you can apply it in a compliance policy to customize an XCCDF profile.

Prerequisite

  • Your user account has the create_tailoring_files permission.

  2. From the Environment list, select the Puppet environment that contains the foreman_scap_client and foreman_scap_client::params Puppet classes.

  3. From the OpenSCAP Smart Proxy list, select the Smart Proxy with OpenSCAP enabled that you want to use.

  4. On the Puppet ENC tab, add the foreman_scap_client Puppet class.

  5. Optional: Configure any Puppet Class Parameters.

  6. Click the Hosts breadcrumbs link to navigate back to the host index page.

  7. Select the host or hosts to which you want to add the policy.

  8. Click Select Action.

  9. Select Assign Compliance Policy from the list.

  10. In the Assign Compliance Policy window, select Remember hosts selection for the next bulk action.

  11. Select the required policy from the list of available policies and click Submit.

6.10. Running a Security Compliance Scan on Demand

Hosts perform OpenSCAP scans regularly by the CRON schedule defined in the compliance policies assigned to hosts. However, you can also run a scan on a host for all configured compliance policies manually at any time.

Prerequisites

  • Your user account has the view_hosts, create_job_invocations, and view_job_invocations permissions.

  • You have created a compliance policy and deployed it on the host.

Procedure

  1. Navigate to Hosts > All Hosts.

  2. Click the hostname of the required host.

  3. On the host details page, expand the Schedule a job dropdown menu.

  4. Select Run OpenSCAP scan.

Verification

  1. In the host details overview, locate the Recent jobs card.

  2. Select the Running tab. Unless the job has already finished, the table shows a job called Run scan for all OpenSCAP policies.

  3. On the Recent jobs card, select the Finished tab.

  4. If the job has finished successfully, you should see the succeeded status in the row of the job.

  5. Optional: Click the job name to review invocation details.

6.11. Monitoring Compliance

With Foreman, you can centralize compliance monitoring and management. A compliance dashboard provides an overview of compliance of hosts and the ability to view details for each host within the scope of that policy. Compliance reports provide a detailed analysis of compliance of each host with the applicable policy. With this information, you can evaluate the risks presented by each host and manage the resources required to bring hosts into compliance. By monitoring compliance with SCAP, you can verify policy compliance and detect changes in compliance.

6.11.1. Searching Compliance Reports

Use the Compliance Reports search field to filter the list of available reports on any subset of hosts.

Procedure

  1. In the Foreman web UI, navigate to Hosts > Reports.

  2. Optional: To see a list of available search parameters, click the empty Search field.

  3. Enter the search query in the Search field and click Search. The search query is case insensitive.

Search Query Examples
Find all compliance reports for which more than five rules failed
failed > 5
Find all compliance reports created after January 1, 2023, for hosts with hostnames that contain prod-
host ~ prod- AND date > "Jan 1, 2023"
Find all reports generated by the rhel7_audit compliance policy from an hour ago
"1 hour ago" AND compliance_policy = date = "1 hour ago" AND compliance_policy = rhel7_audit
Find reports that pass an XCCDF rule
xccdf_rule_passed = xccdf_org.ssgproject.content_rule_firefox_preferences-auto-download_actions
Find reports that fail an XCCDF rule
xccdf_rule_failed = xccdf_org.ssgproject.content_rule_firefox_preferences-auto-download_actions
Find reports that have a result different than fail or pass for an XCCDF rule
xccdf_rule_othered = xccdf_org.ssgproject.content_rule_firefox_preferences-auto-download_actions
Additional Information

  • You can create complex queries with the following logical operators: and, not and has. For more information about logical operators, see Supported Operators for Granular Search in Administering Foreman.

  • You cannot use regular expressions in a search query. However, you can use multiple fields in a single search expression. For more information about all available search operators, see Supported Operators for Granular Search in Administering Foreman.

  • You can bookmark a search to reuse the same search query. For more information, see Creating Bookmarks in Administering Foreman.

6.11.2. Compliance Email Notifications

Foreman server sends an OpenSCAP Summary email to all users who subscribe to the Compliance policy summary email notifications. For more information on subscribing to email notifications, see Configuring Email Notification Preferences.

Each time a policy is run, Foreman checks the results against the previous run, noting any changes between them. The email is sent according to the frequency requested by each subscriber, providing a summary of each policy and its most recent result.

6.11.3. Viewing Compliance Policy Statistics

You can view a compliance policy dashboard to verify compliance reports of a particular policy. The compliance policy dashboard provides a statistical summary of compliance of hosts and the ability to view report details for each host within the scope of that policy.

Consider prioritizing the following hosts when viewing compliance reports:

  • Hosts which were evaluated as Failed

  • Hosts labelled as Never audited because their status is unknown

Prerequisite

  • Your user account has the view_policies permission.

Procedure

  1. In the Foreman web UI, navigate to Hosts > Policies.

  2. In the row of the required policy, navigate to the Actions column and click Dashboard.

6.11.4. Examining Hosts per Rule Compliance Result

You can examine a simplified report and use policy rules to list hosts that have a certain compliance result, such as failing a particular rule.

Prerequisite

  • Your user account has the view_arf_reports and view_hosts permissions.

Procedure

  1. In the Foreman web UI, navigate to Hosts > Reports.

  2. In the Reported At column, navigate to the report of the required host and compliance policy, and click the time link.

  3. Foreman displays a simplified list of policy rules with the results of the scan.

  4. Optional: Filter the rules by check result. From the Show log messages dropdown list, select one of the following filters:

    • Failed and othered – to view rules that have failed or have not been checked during the scan,

    • Failed only – to view only rules that have failed.

  5. Optional: Examine the details of the rule. In the Message column, click the icon next to the name of the rule.

  6. In the row of the required rule, navigate to the Actions column and click Hosts failing this rule.

6.11.5. Examining Compliance Failures of a Host

You can examine a full compliance report, determine why a host failed compliance on a rule, and, in some cases, see how to remediate a case of non-compliance.

Warning

Do not implement any of the recommended remedial actions or scripts without first testing them in a non-production environment. Remediation might render the system non-functional.

A compliance report consists of the following areas:

  • Introduction

  • Evaluation Characteristics

  • Compliance and Scoring

  • Rule Overview

Prerequisite

  • Your user account has the view_arf_reports and view_hosts permissions.

Procedure

  1. In the Foreman web UI, navigate to Hosts > Reports to list all compliance reports.

  2. In the row of the required host, navigate to the Actions column and click Full Report to view the complete details of an evaluation report.

  3. Navigate to the Evaluation Characteristics area to review basic details about the evaluation of the host against a specific profile.

  4. Navigate to the Compliance and Scoring area to review evaluation statistics and the host compliance score.

  5. Navigate to the Rule Overview to examine the rules.

  6. Optional: Deselect the check statuses that you want to hide, such as pass, notapplicable, or fixed.

  7. Optional: From the Group rule by dropdown menu, select the criterion for the grouping of rules, such as Severity.

  8. Optional: Enter a search string into the search field to filter rules by title. The search is case insensitive and applied dynamically as you type.

  9. Click the title of a rule to inspect further result details:

    • A description of the rule with instructions for bringing the host into compliance if available.

    • The rationale for the rule.

    • In some cases, a remediation script.

6.11.6. Deleting a Compliance Report

You can delete compliance reports on your Foreman.

Prerequisite

  • Your user account has the view_arf_reports and destroy_arf_reports permissions.

Procedure

  1. In the Foreman web UI, navigate to Hosts > Reports.

  2. In the Compliance Reports window, identify the policy that you want to delete and, on the right of the policy’s name, select Delete.

  3. Click OK.

6.11.7. Deleting Multiple Compliance Reports

You can delete multiple compliance policies simultaneously. However, in the Foreman web UI, compliance policies are paginated, so you must delete one page of reports at a time.

Prerequisite

  • Your user account has the view_arf_reports and destroy_arf_reports permissions.

Procedure

  1. In the Foreman web UI, navigate to Hosts > Reports.

  2. In the Compliance Reports window, select the compliance reports that you want to delete.

  3. In the upper right of the list, select Delete reports.

  4. Repeat these steps for as many pages as you want to delete.

7. Backing Up Foreman server and Smart Proxy Server

You can back up your Foreman deployment to ensure the continuity of your Foreman deployment and associated data in the event of a disaster. If your deployment uses custom configurations, you must consider how to handle these custom configurations when you plan your backup and disaster recovery policy.

Note

If you create a new instance of the Foreman server, decommission the old instances after restoring the backup. Cloned instances are not supposed to run in parallel in a production environment.

To create a backup of your Foreman server or Smart Proxy server and all associated data, use the foreman-maintain backup command. Backing up to a separate storage device on a separate system is highly recommended.

Foreman services are unavailable during the backup. Therefore, you must ensure that no other tasks are scheduled by other administrators. You can schedule a backup using cron. For more information, see the Example of a Weekly Full Backup Followed by Daily Incremental Backups.

During offline or snapshot backups, the services are inactive and Foreman is in a maintenance mode. All the traffic from outside on port 443 is rejected by a firewall to ensure there are no modifications triggered.

You must encrypt or move the backup to a secure location to minimize the risk of damage or unauthorized access to the hosts.

Conventional Backup Methods

You can also use conventional backup methods. For more information, see Recovering and restoring a system in Red Hat Enterprise Linux 8 Configuring basic system settings.

Note

If you plan to use the foreman-maintain backup command to create a backup, do not stop Foreman services.

  • When creating a snapshot or conventional backup, you must stop all services as follows:

    # foreman-maintain service stop

  • Start the services after creating a snapshot or conventional backup:

    # foreman-maintain service start

7.1. Estimating the Size of a Backup

Note that estimations in this section are for the installations that use the Katello plug-in.

The full backup creates uncompressed archives of PostgreSQL and Pulp database files, and Foreman configuration files. Compression occurs after the archives are created to decrease the time when Foreman services are unavailable.

A full backup requires space to store the following data:

  • Uncompressed Foreman database and configuration files

  • Compressed Foreman database and configuration files

  • An extra 20% of the total estimated space to ensure a reliable backup

Procedure

  1. Enter the du command to estimate the size of uncompressed directories containing Foreman database and configuration files:

    # du -sh /var/lib/pgsql/data /var/lib/pulp
100G    /var/lib/pgsql/data
100G	/var/lib/pulp

# du -csh /var/lib/qpidd /var/lib/tftpboot /etc /root/ssl-build \
/var/www/html/pub /opt/puppetlabs
886M  /var/lib/qpidd
16M   /var/lib/tftpboot
37M   /etc
900K  /root/ssl-build
100K  /var/www/html/pub
2M    /opt/puppetlabs
942M  total

  2. Calculate how much space is required to store the compressed data.

    The following table describes the compression ratio of all data items included in the backup:

    Table 5. Backup Data Compression Ratio
    Data type Directory Ratio Example results

    PostgreSQL database files

    /var/lib/pgsql/data

    80 – 85%

    100 GB → 20 GB

    Pulp RPM files

    /var/lib/pulp

    (not compressed)

    100 GB

    Configuration files

    /var/lib/qpidd
    /var/lib/tftpboot
    /etc
    /root/ssl-build
    /var/www/html/pub
    /opt/puppetlabs

    85%

    942 MB → 141 MB

    In this example, the compressed backup data occupies 120 GB in total.

  3. To calculate the amount of available space you require to store a backup, calculate the sum of the estimated values of compressed and uncompressed backup data, and add an extra 20% to ensure a reliable backup.

    This example requires 201 GB plus 120 GB for the uncompressed and compressed backup data, 321 GB in total. With 64 GB of extra space, 385 GB must be allocated for the backup location.

7.2. Performing a Full Backup of Foreman server or Smart Proxy Server

Foreman uses the foreman-maintain backup command to make backups.

There are three main methods of backing up Foreman server:

  • Offline backup

  • Online backup

  • Snapshot backups

    For more information about each of these methods, you can view the usage statements for each backup method.

Offline backups
# foreman-maintain backup offline --help
Online backups
# foreman-maintain backup online --help
Snapshots backups
# foreman-maintain backup snapshot --help
Directory creation

The foreman-maintain backup command creates a time-stamped subdirectory in the backup directory that you specify. The foreman-maintain backup command does not overwrite backups, therefore you must select the correct directory or subdirectory when restoring from a backup or an incremental backup. The foreman-maintain backup command stops and restarts services as required.

When you run the foreman-maintain backup offline command, the following default backup directories are created:

  • foreman-backup on Foreman

  • foreman-proxy-backup on Smart Proxy

If you want to set a custom directory name, add the --preserve-directory option and add a directory name. The backup is then stored in the directory you provide in the command line. If you use the --preserve-directory option, no data is removed if the backup fails.

Note that if you use a local PostgreSQL database, the postgres user requires write access to the backup directory.

Remote databases

You can use the foreman-maintain backup command to back up remote databases.

You can use both online and offline methods to back up remote databases, but if you use offline methods, such as snapshot, the foreman-maintain backup command performs a database dump.

Prerequisites
Warning

Request other users of Foreman server or Smart Proxy server to save any changes and warn them that Foreman services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup.
Procedure

  • On Foreman server, enter the following command:

    # foreman-maintain backup offline /var/foreman-backup

  • On Smart Proxy server, enter the following command:

    # foreman-maintain backup offline /var/foreman-proxy-backup

7.3. Performing a Backup without Pulp Content

You can perform an offline backup that excludes the contents of the Pulp directory. The backup without Pulp content is useful for debugging purposes and is only intended to provide access to configuration files without backing up the Pulp database. For production usecases, do not restore from a directory that does not contain Pulp content.

Warning

Request other users of Foreman server or Smart Proxy server to save any changes and warn them that Foreman services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup.
Prerequisites
Procedure

  • To perform an offline backup without Pulp content, enter the following command:

    # foreman-maintain backup offline --skip-pulp-content /var/backup_directory

7.4. Performing an Incremental Backup

Use this procedure to perform an offline backup of any changes since a previous backup.

To perform incremental backups, you must perform a full backup as a reference to create the first incremental backup of a sequence. Keep the most recent full backup and a complete sequence of incremental backups to restore from.

Warning

Request other users of Foreman server or Smart Proxy server to save any changes and warn them that Foreman services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup.
Prerequisites
Procedure

  1. To perform a full offline backup, enter the following command:

    # foreman-maintain backup offline /var/backup_directory

  2. To create a directory within your backup directory to store the first incremental back up, enter the foreman-maintain backup command with the --incremental option:

    # foreman-maintain backup offline --incremental /var/backup_directory/full_backup /var/backup_directory

  3. To create the second incremental backup, enter the foreman-maintain backup command with the --incremental option and include the path to the first incremental backup to indicate the starting point for the next increment. This creates a directory for the second incremental backup in your backup directory:

    # foreman-maintain backup offline --incremental /var/backup_directory/first_incremental_backup /var/backup_directory

  4. Optional: If you want to point to a different version of the backup, and make a series of increments with that version of the backup as the starting point, you can do this at any time. For example, if you want to make a new incremental backup from the full backup rather than the first or second incremental backup, point to the full backup directory:

    # foreman-maintain backup offline --incremental /var/backup_directory/full_backup /var/backup_directory

7.5. Example of a Weekly Full Backup Followed by Daily Incremental Backups

The following script performs a full backup on a Sunday followed by incremental backups for each of the following days. A new subdirectory is created for each day that an incremental backup is performed. The script requires a daily cron job.

#!/bin/bash -e
PATH=/sbin:/bin:/usr/sbin:/usr/bin
DESTINATION=/var/backup_directory
if [[ $(date +%w) == 0 ]]; then
  foreman-maintain backup offline --assumeyes $DESTINATION
else
  LAST=$(ls -td -- $DESTINATION/*/ | head -n 1)
  foreman-maintain backup offline --assumeyes --incremental "$LAST" $DESTINATION
fi
exit 0

Note that the foreman-maintain backup command requires /sbin and /usr/sbin directories to be in PATH and the --assumeyes option is used to skip the confirmation prompt.

7.6. Performing an Online Backup

Perform an online backup only for debugging purposes.

Risks Associated with Online Backups

When performing an online backup, if there are procedures affecting the Pulp database, the Pulp part of the backup procedure repeats until it is no longer being altered. Because the backup of the Pulp database is the most time consuming part of backing up Foreman, if you make a change that alters the Pulp database during this time, the backup procedure keeps restarting.

For production environments, use the snapshot method. For more information, see Performing a Snapshot Backup. If you want to use the online backup method in production, proceed with caution and ensure that no modifications occur during the backup.

Warning

Request other users of Foreman server or Smart Proxy server to save any changes and warn them that Foreman services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup.
Prerequisites
Procedure

  • To perform an online backup, enter the following command:

    # foreman-maintain backup online /var/backup_directory

7.7. Performing a Snapshot Backup

You can perform a snapshot backup that uses Logical Volume Manager (LVM) snapshots of the Pulp, and PostgreSQL directories. Creating a backup from LVM snapshots mitigates the risk of an inconsistent backup.

The snapshot backup method is faster than a full offline backup and therefore reduces Foreman downtime.

To view the usage statement, enter the following command:

foreman-maintain backup snapshot -h
Warning

Request other Foreman server or Smart Proxy server users to save any changes and warn them that Foreman services are unavailable for the duration of the backup. Ensure no other tasks are scheduled for the same time as the backup.
Prerequisites

  • The system uses LVM for the directories that you snapshot: /var/lib/pulp/, and /var/lib/pgsql.

  • The free disk space in the relevant volume group (VG) is three times the size of the snapshot. More precisely, the VG must have enough space unreserved by the member logical volumes (LVs) to accommodate new snapshots. In addition, one of the LVs must have enough free space for the backup directory.

  • The target backup directory is on a different LV than the directories that you snapshot.

Procedure

  • To perform a snapshot backup, enter the foreman-maintain backup snapshot command:

    # foreman-maintain backup snapshot /var/backup_directory

The foreman-maintain backup snapshot command creates snapshots when the services are active, and stops all services which can impact the backup. This makes the maintenance window shorter. After the successful snapshot, all services are restarted and LVM snapshots are removed.

7.8. White-listing and Skipping Steps When Performing Backups

A backup using the foreman-maintain backup command proceeds in a sequence of steps. To skip part of the backup add the --whitelist option to the command and add the step label that you want to omit.

Procedure

  • To display a list of available step labels, enter the following command:

    # foreman-maintain advanced procedure run -h

  • To skip a step of the backup, enter the foreman-maintain backup command with the --whitelist option. For example:

    # foreman-maintain backup online --whitelist backup-metadata -y /var/backup_directory

8. Restoring Foreman server or Smart Proxy Server from a Backup

You can restore Foreman server or Smart Proxy server from the backup data that you create as part of Backing Up Foreman server and Smart Proxy Server. This process outlines how to restore the backup on the same server that generated the backup, and all data covered by the backup is deleted on the target system. If the original system is unavailable, provision a system with the same configuration settings and host name.

8.1. Restoring from a Full Backup

Use this procedure to restore Foreman or Smart Proxy server from a full backup. When the restore process completes, all processes are online, and all databases and system configuration revert to the state at the time of the backup.

Prerequisites

  • Ensure that you are restoring to the correct instance. The Foreman instance must have the same host name, configuration, and be the same minor version (X.Y) as the original system.

  • Ensure that you have an existing target directory. The target directory is read from the configuration files contained within the archive.

  • Ensure that you have enough space to store this data on the base system of Foreman server or Smart Proxy server as well as enough space after the restoration to contain all the data in the /etc/ and /var/ directories contained within the backup.

    To check the space used by a directory, enter the following command:

    # du -sh /var/backup_directory

    To check for free space, enter the following command:

    # df -h /var/backup_directory

    Add the --total option to get a total of the results from more than one directory.

  • Ensure that all SELinux contexts are correct. Enter the following command to restore the correct SELinux contexts:

    # restorecon -Rv /
Procedure

  1. Choose the appropriate method to install Foreman or Smart Proxy:

  2. Copy the backup data to Foreman server’s local file system. Use /var/ or /var/tmp/.

  3. Run the restoration script.

    # foreman-maintain restore /var/backup_directory

    Where backup_directory is the time-stamped directory or subdirectory containing the backed-up data.

    The restore process can take a long time to complete, because of the amount of data to copy.

Additional Resources

  • For troubleshooting, you can check /var/log/foreman/production.log and /var/log/messages.

8.2. Restoring from Incremental Backups

Use this procedure to restore Foreman or Smart Proxy server from incremental backups. If you have multiple branches of incremental backups, select your full backup and each incremental backup for the branch you want to restore, in chronological order.

When the restore process completes, all processes are online, and all databases and system configuration revert to the state at the time of the backup.

Procedure

  1. Restore the last full backup using the instructions in Restoring from a Full Backup.

  2. Remove the full backup data from Foreman server’s local file system, for example, /var/ or /var/tmp/.

  3. Copy the incremental backup data to Foreman server’s local file system, for example, /var/ or /var/tmp/.

  4. Restore the incremental backups in the same sequence that they are made:

    # foreman-maintain restore /var/backup_directory/FIRST_INCREMENTAL
# foreman-maintain restore /var/backup_directory/SECOND_INCREMENTAL
Additional Resources

  • For troubleshooting, you can check /var/log/foreman/production.log and /var/log/messages.

8.3. Backup and Restore Smart Proxy Server Using a Virtual Machine Snapshot

If your Smart Proxy server is a virtual machine, you can restore it from a snapshot. Creating weekly snapshots to restore from is recommended. In the event of failure, you can install, or configure a new Smart Proxy server, and then synchronize the database content from Foreman server.

If required, deploy a new Smart Proxy server, ensuring the host name is the same as before, and then install the Smart Proxy certificates. You may still have them on Foreman server, the package name ends in -certs.tar, alternately create new ones. Follow the procedures in Installing Smart Proxy server until you can confirm, in the Foreman web UI, that Smart Proxy server is connected to Foreman server. Then use the procedure Synchronizing an External Smart Proxy to synchronize from Foreman.

8.3.1. Synchronizing an External Smart Proxy

Synchronize an external Smart Proxy with Foreman.

Procedure

  1. To synchronize an external Smart Proxy, select the relevant organization and location in the Foreman web UI, or choose Any Organization and Any Location.

  2. In the Foreman web UI, navigate to Infrastructure > Smart Proxies and click the name of the Smart Proxy to synchronize.

  3. On the Overview tab, select Synchronize.

9. Maintaining Foreman server

This chapter provides information on how to maintain a Foreman server, including information on how to work with audit records, how to clean unused tasks, and how to recover Pulp from a full disk.

9.1. Deleting Audit Records Manually

You can use the foreman-rake audits:expire command to remove audit records at any time.

Procedure

  • Delete the audit records using the foreman-rake audits:expire command:

    # foreman-rake audits:expire days=Number_Of_Days

    This command deletes all audit records older than Number_Of_Days.

9.2. Deleting Audit Records Automatically

You can automatically delete audit records using the Saved audits interval setting. This setting is empty by default, meaning Foreman does not automatically delete the audit records.

Procedure

  1. In the Foreman web UI, navigate to Administer > Settings.

  2. On the General tab, find the Saved audits interval setting.

  3. Set the value of the setting to the number of days after which you want Foreman to delete the audit records.

9.3. Anonymizing Audit Records

You can use the foreman-rake audits:anonymize command to remove any user account or IP information while maintaining the audit records in the database. You can also use a cron job to schedule anonymizing the audit records at the set interval that you want.

By default, using the foreman-rake audits:anonymize command anonymizes audit records that are older than 90 days. You can specify the number of days to keep the audit records by adding the days option and add the number of days.

For example, if you want to anonymize audit records that are older than seven days, enter the following command:

# foreman-rake audits:anonymize days=7

9.4. Deleting Report Records

Report records are created automatically in Foreman. You can use the foreman-rake reports:expire command to remove reports at any time. You can also use a cron job to schedule report record deletions at the set interval that you want.

By default, using the foreman-rake reports:expire command removes report records that are older than 90 days. You can specify the number of days to keep the report records by adding the days option and add the number of days.

For example, if you want to delete report records that are older than seven days, enter the following command:

# foreman-rake reports:expire days=7

9.5. Configuring the Cleaning Unused Tasks Feature

Foreman performs regular cleaning to reduce disc space in the database and limit the rate of disk growth. As a result, Foreman backup completes faster and overall performance is higher.

By default, Foreman executes a cron job that cleans tasks every day at 19:45. Foreman removes the following tasks during the cleaning:

  • Tasks that have run successfully and are older than thirty days

  • All tasks that are older than a year

You can configure the cleaning unused tasks feature using these options:

  • To configure the time at which Foreman runs the cron job, set the --foreman-plugin-tasks-cron-line parameter to the time you want in cron format. For example, to schedule the cron job to run every day at 15:00, enter the following command:

    # foreman-installer --foreman-plugin-tasks-cron-line "00 15 * * *"

  • To configure the period after which Foreman deletes the tasks, edit the :rules: section in the /etc/foreman/plugins/foreman-tasks.yaml file.

  • To disable regular task cleanup on Foreman, enter the following command:

    # foreman-installer --foreman-plugin-tasks-automatic-cleanup false

  • To reenable regular task cleanup on Foreman, enter the following command:

    # foreman-installer --foreman-plugin-tasks-automatic-cleanup true

9.6. Deleting Task Records

Task records are created automatically in Foreman. You can use the foreman-rake foreman_tasks:cleanup command to remove tasks at any time. You can also use a cron job to schedule Task record deletions at the set interval that you want.

For example, if you want to delete task records from successful repository synchronizations, enter the following command:

# foreman-rake foreman_tasks:cleanup TASK_SEARCH='label = Actions::Katello::Repository::Sync' STATES='stopped'

9.7. Deleting a Task by ID

You can delete tasks by ID, for example if you have submitted confidential data by mistake.

Procedure

  1. Connect to your Foreman server using SSH:

    # ssh root@foreman.example.com

  2. Optional: View the task:

    # hammer task info --id My_Task_ID

  3. Delete the task:

    # foreman-rake foreman_tasks:cleanup TASK_SEARCH="id=My_Task_ID"

  4. Optional: Ensure the task has been removed from Foreman server:

    # hammer task info --id My_Task_ID

    Note that because the task is deleted, this command returns a non-zero exit code.

9.8. Reclaiming PostgreSQL Space

The PostgreSQL database can use a large amount of disk space especially in heavily loaded deployments. Use this procedure to reclaim some of this disk space on Foreman.

Procedure

  1. Stop all services, except for the postgresql service:

    # foreman-maintain service stop --exclude postgresql

  2. Switch to the postgres user and reclaim space on the database:

    # su - postgres -c 'vacuumdb --full --all'

  3. Start the other services when the vacuum completes:

    # foreman-maintain service start

10. Logging and Reporting Problems

This chapter provides information on how to log and report problems in Foreman, including information on relevant log files, how to enable debug logging, how to open a support case and attach the relevant log tar files, and how to access support cases within the Foreman web UI.

For more information about Foreman logging settings, use foreman-installer with the --full-help option:

# foreman-installer --full-help | grep logging

10.1. Enabling Debug Logging

Debug logging provides the most detailed log information and can help with troubleshooting issues that can arise with Foreman and its components. In the Foreman CLI, enable debug logging to log detailed debugging information for Foreman.

Procedure

  1. To enable debug logging, enter the following command:

    # foreman-installer --foreman-logging-level debug

  2. After you complete debugging, reset the logging level to the default value:

    # foreman-installer --reset-foreman-logging-level

10.2. Increasing the Logging Levels to Help with Debugging

By default, Foreman comes with :INFO level logging enabled. You can increase or decrease the log levels on your Foreman.

Enabling debug level logging on all components
# hammer admin logging --all --level-debug
# foreman-maintain service restart
Enabling debug level logging for a specific component
# hammer admin logging --components "Component" --level-debug
Reverting debug level logging to INFO
# hammer admin logging --all --level-production
# foreman-maintain service restart
Listing all components and changed configuration files
# hammer admin logging --list

--foreman-loggers sql:true

  2. Optional: To reset loggers to their default values, enter the following command:

    # foreman-installer --reset-foreman-loggers

10.6. Configuring Logging to Journal or File-based Logging

Foreman uses file-based logging by default. You can use the foreman-installer command to reconfigure logging.

Procedure for configuring logging with Journal

  1. Enter the following foreman-installer command to configure logging to the journald service:

    # foreman-installer \
--foreman-logging-layout pattern \
--foreman-logging-type journald \
--foreman-proxy-log JOURNAL

  2. Optional: To inspect the log messages, use the journalctl utility. For example:

    • journalctl --unit foreman and journalctl --unit foreman-proxy show messages for the foreman and foreman-proxy units

    • journalctl REQUEST=request_ID shows messages for a specified request

Procedure for configuring file-based logging

  1. Enter the following foreman-installer command to configure file-based logging:

    # foreman-installer \
--reset-foreman-logging-layout \
--reset-foreman-logging-type \
--reset-foreman-proxy-log

  2. Optional: To inspect the log messages, view these files:

    • /var/log/foreman/production.log

    • /var/log/foreman-proxy.log

10.7. Log File Directories Provided by Foreman

Foreman provides system information in the form of notifications and log files.

Table 6. Log File Directories for Reporting and Troubleshooting
Log File Directories Description of Log File Content

/var/log/candlepin

You can also use the foreman-tail command to follow many of the log files related to Foreman. You can run foreman-tail -l to list the processes and services that it follows.

10.8. Utilities for Collecting Log Information

You can collect information from log files to troubleshoot Foreman.

sosreport

The sosreport command collects configuration and diagnostic information from a Linux system, such as the running Kernel version, loaded modules, running services, and system and service configuration files. This output is stored in a tar file located at /var/tmp/sosreport-XXX-20171002230919.tar.xz. For more information, run sosreport --help or see What is a sosreport and how can I create one?.

Important

The collection process removes security information such as passwords, tokens, and keys while collecting information. However, the tar files can still contain sensitive information about the Foreman server. Foreman community recommends that you send this information directly to the intended recipient and not to a public target.

10.9. System Journal Metadata

The following table lists metadata that the journald service uses in Foreman. You can use this metadata to filter your queries.

Note

It is not possible to change the date format displayed in the Foreman web UI.

11.1.1. Managing Tasks

Foreman keeps a complete log of all planned or performed tasks, such as repositories synchronised, errata applied, and Content Views published. To review the log, navigate to Monitor > Tasks.

In the Task window, you can search for specific tasks, view their status, details, and elapsed time since they started. You can also cancel and resume one or more tasks.

The tasks are managed using the Dynflow engine. Remote tasks have a timeout which can be adjusted as needed.

To Adjust Timeout Settings:

  1. In the Foreman web UI, navigate to Administer > Settings.

  2. Enter %_timeout in the search box and click Search. The search should return four settings, including a description.

  3. In the Value column, click the icon next to a number to edit it.

  4. Enter the desired value in seconds, and click Save.

Note

Adjusting the %_finish_timeout values might help in case of low bandwidth. Adjusting the %_accept_timeout values might help in case of high latency.

When a task is initialized, any back-end service that will be used in the task, such as Candlepin or Pulp, will be checked for correct functioning. If the check fails, you will receive an error similar to the following one:

There was an issue with the backend service candlepin: Connection refused – connect(2).

If the back-end service checking feature turns out to be causing any trouble, it can be disabled as follows.

To Disable Checking for Services:

  1. In the Foreman web UI, navigate to Administer > Settings.

  2. Enter check_services_before_actions in the search box and click Search.

  3. In the Value column, click the icon to edit the value.

  4. From the drop-down menu, select false.

  5. Click Save.

11.2. Configuring RSS Notifications

11.4. Monitoring Smart Proxy Server

The following section shows how to use the Foreman web UI to find Smart Proxy information valuable for maintenance and troubleshooting.

11.4.1. Viewing General Smart Proxy Information

In the Foreman web UI, navigate to Infrastructure > Smart Proxies to view a table of Smart Proxy servers registered to Foreman server. The information contained in the table answers the following questions:

Is Smart Proxy server running?

This is indicated by a green icon in the Status column. A red icon indicates an inactive Smart Proxy, use the service foreman-proxy restart command on Smart Proxy server to activate it.

What services are enabled on Smart Proxy server?

In the Features column you can verify if Smart Proxy for example provides a DHCP service or acts as a Pulp mirror. Smart Proxy features can be enabled during installation or configured in addition. For more information, see Installing Smart Proxy server.

What organizations and locations is Smart Proxy server assigned to?

A Smart Proxy server can be assigned to multiple organizations and locations, but only Smart Proxies belonging to the currently selected organization are displayed. To list all Smart Proxies, select Any Organization from the context menu in the top left corner.

After changing the Smart Proxy configuration, select Refresh from the drop-down menu in the Actions column to ensure the Smart Proxy table is up to date.

Click the Smart Proxy name to view further details. At the Overview tab, you can find the same information as in the Smart Proxy table. In addition, you can answer to the following questions:

Which hosts are managed by Smart Proxy server?

The number of associated hosts is displayed next to the Hosts managed label. Click the number to view the details of associated hosts.

How much storage space is available on Smart Proxy server?

The amount of storage space occupied by the Pulp content in /var/lib/pulp is displayed. Also the remaining storage space available on the Smart Proxy can be ascertained.

11.4.2. Monitoring Services

In the Foreman web UI, navigate to Infrastructure > Smart Proxies and click the name of the selected Smart Proxy. At the Services tab, you can find basic information on Smart Proxy services, such as the list of DNS domains, or the number of Pulp workers. The appearance of the page depends on what services are enabled on Smart Proxy server. Services providing more detailed status information can have dedicated tabs at the Smart Proxy page. For more information, see Monitoring Puppet.

11.4.3. Monitoring Puppet

In the Foreman web UI, navigate to Infrastructure > Smart Proxies and click the name of the selected Smart Proxy. At the Puppet tab you can find the following:

  • A summary of Puppet events, an overview of latest Puppet runs, and the synchronization status of associated hosts at the General sub-tab.

  • A list of Puppet environments at the Environments sub-tab.

At the Puppet CA tab you can find the following:

  • A certificate status overview and the number of autosign entries at the General sub-tab.

  • A table of CA certificates associated with the Smart Proxy at the Certificates sub-tab. Here you can inspect the certificate expiry data, or cancel the certificate by clicking Revoke.

  • A list of autosign entries at the Autosign entries sub-tab. Here you can create an entry by clicking New or delete one by clicking Delete.

12. Using Webhooks

A webhook is a way for a web page or web application to provide other applications with information in real time. Webhooks are only triggered after an event occurs. The request usually contains details of the event. An event triggers callbacks, such as sending an e-mail confirming a host has been provisioned. Webhooks enable you to define a call to an external API based on Foreman internal event using a fire-and-forget message exchange pattern. The application sending the request does not wait for the response, or ignores it.

Payload of a webhook is created from webhook templates. Webhook templates use the same ERB syntax as Provisioning templates. Available variables:

  • @event_name: Name of an event.

  • @webhook_id: Unique event ID.

  • @payload: Payload data, different for each event type. To access individual fields, use @payload[:key_name] Ruby hash syntax.

  • @payload[:object]: Database object for events triggered by database actions (create, update, delete). Not available for custom events.

  • @payload[:context]: Additional information as hash like request and session UUID, remote IP address, user, organization and location.

Because webhooks use HTTP, no new infrastructure needs be added to existing web services.

The typical use case for webhooks in Foreman is making a call to a monitoring system when a host is created or deleted.

Webhooks are useful where the action you want to perform in the external system can be achieved through its API. Where it is necessary to run additional commands or edit files, the shellhooks plugin for Smart Proxies is available. The shellhooks plugin enables you to define a shell script on the Smart Proxy that can be executed through the API.

You can use webhooks successfully without installing the shellhooks plugin.

For a list of available events, see Available webhook events.

12.1. Migrating to Webhooks

The legacy foreman_hooks plugin provided full access to model objects that the webhooks plugin does not intentionally provide.

The scope of what is available is limited by the safemode and all objects and macros are both subject to an API stability promise and are fully documented.

The number of events triggered by webhooks is substantially fewer than with foreman_hooks.

Webhooks are processed asynchronously so there is minimal risk of tampering with internals of the system. It is not possible to migrate from foreman_hooks without creating payloads for each individual webhook script. However, the webhooks plugin comes with several example payload templates. You can also use the example payloads with shellhooks to simplify migration.

Both script and payload templates must be customized to achieve similar results.

12.2. Installing Webhooks

Use the following procedure to install webhooks. After installing webhooks, you can configure Foreman server to send webhook requests.

Procedure

  • Install webhooks using the following command:

    # foreman-installer --enable-foreman-plugin-webhooks

  • Optional: you can install the CLI plugin using the following command:

    # foreman-installer --enable-foreman-cli-webhooks

12.3. Creating a Webhook Template

Webhook templates are used to generate the body of HTTP request to a configured target when a webhook is triggered. Use the following procedure to create a webhook template in the Foreman web UI.

Procedure

  1. In the Foreman web UI, navigate to Administer > Webhook Templates.

  2. Click Clone an existing template or Create Template.

  3. Enter a name for the template.

  4. Use the editor to make changes to the template payload.

    A webhook HTTP payload must be created using Foreman template syntax. The webhook template can use a special variable called @object that can represent the main object of the event. @object can be missing in case of certain events. You can determine what data are actually available with the @payload variable.

    For more information, see Template Writing Reference in Managing Hosts and for available template macros and methods, visit /templates_doc on Foreman server.

  5. Optional: Enter the description and audit comment.

  6. Assign organizations and locations.

  7. Click Submit.

Examples

When creating a webhook template, you must follow the format of the target application for which the template is intended. For example, an application can expect a "text" field with the webhook message. Refer to the documentation of your target application to find more about how your webhook template format should look like.

Running remote execution jobs

This webhook template defines a message with the ID and result of a remote execution job. The webhook which uses this template can be subscribed to events such as Actions Remote Execution Run Host Job Succeeded or Actions Remote Execution Run Host Job Failed.

{
    "text": "job invocation <%= @object.job_invocation_id %> finished with result <%= @object.task.result %>"
}
Creating users

This webhook template defines a message with the login and email of a created user. The webhook which uses this template should be subscribed to the User Created event.

{
    "text": "user with login <%= @object.login %> and email <%= @object.mail %> created"
}

12.4. Creating a Webhook

You can customize events, payloads, HTTP authentication, content type, and headers through the Foreman web UI.

Use the following procedure to create a webhook in the Foreman web UI.

Procedure

  1. In the Foreman web UI, navigate to Administer > Webhooks.

  2. Click Create new.

  3. From the Subscribe to list, select an event.

  4. Enter a Name for your webhook.

  5. Enter a Target URL. Webhooks make HTTP requests to pre-configured URLs. The target URL can be a dynamic URL.

  6. Click Template to select a template. Webhook templates are used to generate the body of the HTTP request to Foreman server when a webhook is triggered.

  7. Enter an HTTP method.

  8. Optional: If you do not want activate the webhook when you create it, uncheck the Enabled flag.

  9. Click the Credentials tab.

  10. Optional: If HTTP authentication is required, enter User and Password.

  11. Optional: Uncheck Verify SSL if you do not want to verify the server certificate against the system certificate store or Foreman CA.

  12. On the Additional tab, enter the HTTP Content Type. For example, application/json, application/xml or text/plain on the payload you define. The application does not attempt to convert the content to match the specified content type.

  13. Optional: Provide HTTP headers as JSON. ERB is also allowed.

When configuring webhooks with endpoints with non-standard HTTP or HTTPS ports, an SELinux port must be assigned, see Configuring SELinux to Ensure Access to Foreman on Custom Ports in Installing Foreman 3.5 Server on RHEL/CentOS.

12.5. Available Webhook Events

The following table contains a list of webhook events that are available from the Foreman web UI. Action events trigger webhooks only on success, so if an action fails, a webhook is not triggered.

For more information about payload, go to Administer > About > Support > Templates DSL. A list of available types is provided in the following table. Some events are marked as custom, in that case, the payload is an object object but a Ruby hash (key-value data structure) so syntax is different.

12.6. Shellhooks

With webhooks, you can only map one Foreman event to one API call. For advanced integrations, where a single shell script can contain multiple commands, you can install a Smart Proxy shellhooks plugin that exposes executables using a REST HTTP API.

You can then configure a webhook to reach out to a Smart Proxy API to run a predefined shellhook. A shellhook is an executable script that can be written in any language as long as it can be executed. The shellhook can for example contain commands or edit files.

You must place your executable scripts in /var/lib/foreman-proxy/shellhooks with only alphanumeric characters and underscores in their name.

You can pass input to shellhook script through the webhook payload. This input is redirected to standard input of the shellhook script. You can pass arguments to shellhook script using HTTP headers in format X-Shellhook-Arg-1 to X-Shellhook-Arg-99. For more information on passing arguments to shellhook script, see:

The HTTP method must be POST. An example URL would be: https://smartproxy.example.com:8443/shellhook/My_Script.

Note

Unlike the shellhooks directory, the URL must contain /shellhook/ in singular to be valid.

You must enable Smart Proxy Authorization for each webhook connected to a shellhook to enable it to authorize a call.

Standard output and standard error output are redirected to the Smart Proxy logs as messages with debug or warning levels respectively.

The shellhook HTTPS calls do not return a value.

For an example on creating a shellhook script, see Creating a Shellhook to Print Arguments.

12.7. Installing the Shellhooks Plugin

Optionally, you can install and enable the shellhooks plugin on each Smart Proxy used for shellhooks, using the following command:

# foreman-installer --enable-foreman-proxy-plugin-shellhooks

12.8. Passing Arguments to Shellhook Script Using Webhooks

Use this procedure to pass arguments to a shellhook script using webhooks.

Procedure

  • When creating a webhook, on the Additional tab, create HTTP headers in the following format:

    {
  "X-Shellhook-Arg-1": "VALUE",
  "X-Shellhook-Arg-2": "VALUE"
}

    Ensure that the headers have a valid JSON or ERB format. Only pass safe fields like database ID, name, or labels that do not include new lines or quote characters.

    For more information, see Creating a Webhook.

Example
{
  "X-Shellhook-Arg-1": "<%= @object.content_view_version_id %>",
  "X-Shellhook-Arg-2": "<%= @object.content_view_name %>"
}

12.9. Passing Arguments to Shellhook Script Using Curl

Use this procedure to pass arguments to a shellhook script using curl.

Procedure

  • When executing a shellhook script using curl, create HTTP headers in the following format:

    "X-Shellhook-Arg-1: VALUE"
"X-Shellhook-Arg-2: VALUE"
Example
# curl -sX POST -H 'Content-Type: text/plain' \
-H "X-Shellhook-Arg-1: Version 1.0" \
-H "X-Shellhook-Arg-2: My Content View" \
--data "" https://smartproxy.example.com:8443/shellhook/My_Script

12.10. Creating a Shellhook to Print Arguments

Create a simple shellhook script that prints "Hello World!" when you run a remote execution job.

Prerequisite
Procedure

  1. Modify the /var/lib/foreman-proxy/shellhooks/print_args script to print arguments to standard error output so you can see them in the Smart Proxy logs:

    #!/bin/sh
#
# Prints all arguments to stderr
#
echo "$@" >&2

  2. In the Foreman web UI, navigate to Administer > Webhooks.

  3. Click Create new.

  4. From the Subscribe to list, select Actions Remote Execution Run Host Job Succeeded.

  5. Enter a Name for your webhook.

  6. In the Target URL field, enter the URL of your Smart Proxy server followed by :8443/shellhook/print_args:

    https://smartproxy.example.com:8443/shellhook/print_args

    Note that shellhook in the URL is singular, unlike the shellhooks directory.

  7. From the Template list, select Empty Payload.

  8. On the Credentials tab, check Smart Proxy Authorization.

  9. On the Additional tab, enter the following text in the Optional HTTP headers field:

    {
    "X-Shellhook-Arg-1": "Hello",
    "X-Shellhook-Arg-2": "World!"
}

  10. Click Submit. You now have successfully created a shellhook that prints "Hello World!" to Smart Proxy logs every time you a remote execution job succeeds.

Verification

  1. Run a remote execution job on any host. You can use time as a command. For more information, see Executing a Remote Job in Managing Hosts.

  2. Verify that the shellhook script was triggered and printed "Hello World!" to Smart Proxy server logs:

    # tail /var/log/foreman-proxy/proxy.log

    You should find the following lines at the end of the log:

    [I] Started POST /shellhook/print_args
[I] Finished POST /shellhook/print_args with 200 (0.33 ms)
[I] [3520] Started task /var/lib/foreman-proxy/shellhooks/print_args\ Hello\ World\!
[W] [3520] Hello World!

13. Searching and Bookmarking

Foreman features powerful search functionality on most pages of the Foreman web UI. It enables you to search all kinds of resources that Foreman manages. Searches accept both free text and syntax-based queries, which can be built using extensive input prediction. Search queries can be saved as bookmarks for future reuse.

13.1. Building Search Queries

As you start typing a search query, a list of valid options to complete the current part of the query appears. You can either select an option from the list and keep building the query using the prediction, or continue typing. To learn how free text is interpreted by the search engine, see Using Free Text Search.

13.1.1. Query Syntax

parameter operator value

Available fields, resources to search, and the way the query is interpreted all depend on context, that is, the page where you perform the search. For example, the field "hostgroup" on the Hosts page is equivalent to the field "name" on the Host Groups page. The field type also determines available operators and accepted values.

For a list of all operators, see Operators. For descriptions of value formats, see Values.

13.1.2. Query Operators

All operators that can be used between parameter and value are listed in the following table. Other symbols and special characters that might appear in a prediction-built query, such as colons, do not have special meaning and are treated as free text.

Table 11. Comparison Operators Accepted by Search
Operator Short Name Description Example

=

EQUALS

Accepts numerical, temporal, or text values. For text, exact case sensitive matches are returned.

hostgroup = RHEL7

!=

NOT EQUALS

~

LIKE

Accepts text or temporal values. Returns case insensitive matches. Accepts the following wildcards: _ for a single character, % or * for any number of characters including zero. If no wildcard is specified, the string is treated as if surrounded by wildcards: %rhel7%

hostgroup ~ rhel%

!~

NOT LIKE

>

GREATER THAN

Accepts numerical or temporal values. For temporal values, the operator > is interpreted as "later than", and < as "earlier than". Both operators can be combined with EQUALS: >= <=

registered_at > 10-January-2017
The search will return hosts that have been registered after the given date, that is, between 10th January 2017 and now.

registered_at <= Yesterday
The search will return hosts that have been registered yesterday or earlier.

<

LESS THAN

^

IN

Compares an expression against a list of values, as in SQL. Returns matches that contain or not contain the values, respectively.

release_version !^ 7

!^

NOT IN

HAS or set?

 

Returns values that are present or not present, respectively.

has hostgroup or set? hostgroup
On the Puppet Classes page, the search will return classes that are assigned to at least one host group.

not has hostgroup or null? hostgroup
On the Dashboard with an overview of hosts, the search will return all hosts that have no assigned host group.

NOT HAS or null?

 

Simple queries that follow the described syntax can be combined into more complex ones using logical operators AND, OR, and NOT. Alternative notations of the operators are also accepted:

Table 12. Logical Operators Accepted by Search
Operator Alternative Notations Example

and

&

&&

<whitespace>

class = motd AND environment ~ production

or

|

||

 

errata_status = errata_needed || errata_status = security_needed

not

–

!

 

hostgroup ~ rhel7 not status.failed

13.1.3. Query Values

Text Values

Text containing whitespaces must be enclosed in quotes. A whitespace is otherwise interpreted as the AND operator.

Examples:

hostgroup = "Web servers"

The search will return hosts with assigned host group named "Web servers".

hostgroup = Web servers

The search will return hosts in the host group Web with any field matching %servers%.

Temporal Values

Many date and time formats are accepted, including the following:

  • "10 January 2017"

  • "10 Jan 2017"

  • 10-January-2017

  • 10/January/2017

  • "January 10, 2017"

  • Today, Yesterday, and the like.

Warning

Avoid ambiguous date formats, such as 02/10/2017 or 10-02-2017.

13.2. Using Free Text Search

When you enter free text, it will be searched for across multiple fields. For example, if you type "64", the search will return all hosts that have that number in their name, IP address, MAC address, and architecture.

Note

Multi-word queries must be enclosed in quotes, otherwise the whitespace is interpreted as the AND operator.

Because of searching across all fields, free text search results are not very accurate and searching can be slow, especially on a large number of hosts. For this reason, we recommend that you avoid free text and use more specific, syntax-based queries whenever possible.

13.3. Managing Bookmarks

You can save search queries as bookmarks for reuse. You can also delete or modify a bookmark.

Bookmarks appear only on the page on which they were created. On some pages, there are default bookmarks available for the common searches, for example, all active or disabled hosts.

13.3.1. Creating Bookmarks

This section details how to save a search query as a bookmark. You must save the search query on the relevant page to create a bookmark for that page, for example, saving a host related search query on the Hosts page.

Procedure

  1. In the Foreman web UI, navigate to the page where you want to create a bookmark.

  2. In the Search field, enter the search query you want to save.

  3. Select the arrow to the right of the Search button and then select Bookmark this search.

  4. In the Name field, enter a name for the new bookmark.

  5. In the Search query field, ensure your search query is correct.

  6. Ensure the Public checkbox is set correctly:

    • Select the Public checkbox to set the bookmark as public and visible to all users.

    • Clear the Public checkbox to set the bookmark as private and only visible to the user who created it.

  7. Click Submit.

To confirm the creation, either select the arrow to the right of the Search button to display the list of bookmarks, or navigate to Administer > Bookmarks and then check the Bookmarks list for the name of the bookmark.

13.3.2. Deleting Bookmarks

You can delete bookmarks on the Bookmarks page.

Procedure

  1. In the Foreman web UI, navigate to Administer > Bookmarks.

  2. On the Bookmarks page, click Delete for the Bookmark you want to delete.

  3. When the confirmation window opens, click OK to confirm the deletion.

To confirm the deletion, check the Bookmarks list for the name of the bookmark.

Unattended URL

URL that hosts retrieve templates from during the build. When it starts with https, unattended, or userdata, controllers cannot be accessed using HTTP.

Safemode rendering

Yes

Enables safe mode rendering of provisioning templates. The default and recommended option Yes denies access to variables and any object that is not listed in Foreman.

When set to No, any object may be accessed by a user with permission to use templating features, either by editing templates, parameters or smart variables. This permits users full remote code execution on Foreman server, effectively disabling all authorization. This is not a safe option, especially in larger companies.

Type of name generator

Random-based

Specifies the method used to generate a hostname when creating a new host.

The default Random-based option generates a unique random hostname which you can but do not have to use. This is useful for users who create many hosts and do not know how to name them.

The MAC-based option is for bare-metal hosts only. If you delete a host and create it later on, it receives the same hostname based on the MAC address. This can be useful for users who recycle servers and want them to always get the same hostname.

The Off option disables the name generator function and leaves the hostname field blank.

Default PXE global template entry

No

Whether the IP addresses on host interfaces are preferred over the FQDN. It is useful when the DNS is not resolving the FQDNs properly. You can override this per host by setting the remote_execution_connect_by_ip parameter. For dual-stacked hosts, consider the remote_execution_connect_by_ip_prefer_ipv6 setting.

Prefer IPv6 over IPv4

No

When connecting using an IP address, are IPv6 addresses preferred? If no IPv6 address is set, it falls back to IPv4 automatically. You can override this per host by setting the remote_execution_connect_by_ip_prefer_ipv6 parameter. By default and for compatibility, IPv4 is preferred over IPv6.
