Provisioning Hosts

Set the first booting device as boot configuration with network.

Set the second booting device as boot from hard drive. Foreman manages TFTP boot configuration files so hosts can be easily provisioned just by rebooting.

Set the first booting device as boot configuration with network.

Depending on the EFI firmware type and configuration, the OS installer typically configures the OS boot loader as the first entry.

To reboot into installer again, use efibootmgr utility to switch back to boot from network.

You create a host and select a domain and subnet. Foreman requests an available IP address from the DHCP Smart Proxy server that is associated with the subnet or from the PostgreSQL database in Foreman. Foreman loads this IP address into the IP address field in the Create Host window. When you complete all the options for the new host, submit the new host request.

Depending on the configuration specifications of the host and its domain and subnet, Foreman creates the following settings:

The host is configured to boot from the network as the first device and HDD as the second device.

The new host requests a DHCP reservation from the DHCP server.

The DHCP server responds to the reservation request and returns TFTP next-server and filename options.

The host requests the boot loader and menu from the TFTP server according to the PXELoader setting.

A boot loader is returned over TFTP.

The boot loader fetches configuration for the host through its provisioning interface MAC address.

The boot loader fetches the operating system installer kernel, init RAM disk, and boot parameters.

The installer requests the provisioning template from Foreman.

Foreman renders the provision template and returns the result to the host.

The installer performs installation of the operating system.

The PXE configuration files revert to a local boot template.

The host reboots.

The new host requests a DHCP reservation from the DHCP server.

The DHCP server responds to the reservation request and returns TFTP next-server and filename options.

The host requests the bootloader and menu from the TFTP server according to the PXELoader setting.

A boot loader is returned over TFTP.

The boot loader fetches the configuration for the host through its provision interface MAC address.

The boot loader initiates boot from the local drive.

If you configured the host to use any Puppet classes, the host configures itself using the modules.

The host is configured to boot from the network as the first device and HDD as the second device.

The new host requests a DHCP reservation from the DHCP server.

The DHCP server responds to the reservation request and returns TFTP next-server and filename options.

The host requests the boot loader and menu from the TFTP server according to the PXELoader setting.

A boot loader is returned over TFTP.

The boot loader fetches the configuration settings for the host through its provisioning interface MAC address.

For BIOS hosts:

For EFI hosts:

If the host is unknown to Foreman, a default bootloader configuration is provided. When Discovery service is enabled, it boots into discovery, otherwise it boots from HDD.

If a discovered host uses a subnet defined in Foreman, the host uses the first organization and location associated with the subnet.

If the default location and organization is configured in global settings, the discovered hosts are placed in this organization and location. To configure these settings, navigate to Administer > Settings > Discovery and select values for the Discovery organization and Discovery location settings. Ensure that the subnet of discovered host also belongs to the selected organization and location, otherwise Foreman refuses to set it for security reasons.

If none of the previous conditions is met, Foreman assigns the first organization and location ordered by name.

In the Foreman web UI, navigate to Administer > Settings and click the Provisioning tab.

For the Default PXE global template entry, in the Value column, enter discovery.

In the Foreman web UI, navigate to Hosts > Discovered host. Select the host you want to use and click Provision to the right of the list.

In the Search field, enter the rules to determine whether to provision a host. This field provides suggestions for values you enter and allows operators for multiple rules. For example: cpu_count > 8.

From the Host Group list, select the host group to use as a template for this host.

In the Hostname field, enter the pattern to determine host names for multiple hosts. This uses the same ERB syntax that provisioning templates use. The host name can use the @host attribute for host-specific values and the rand macro for a random number or the sequence_hostgroup_param_next macro for incrementing the value. For more information about provisioning templates, see Provisioning Templates and the API documentation.

In the Hosts limit field, enter the maximum number of hosts that you can provision with the rule. Enter 0 for unlimited.

In the Priority field, enter a number to set the precedence the rule has over other rules. Rules with lower values have a higher priority.

--hosts-limit 5 \
--name "My_Hypervisor" \
--priority 5 \
--search "cpu_count  > 8"

Automatically provision a host with the hammer discovery auto-provision command:

# hammer discovery auto-provision --name "macabcdef123456"

Copy this media to either a CD, DVD, or a USB stick. For example, to copy to a USB stick at /dev/sdb:

# dd bs=4M \
if=/usr/share/foreman-discovery-image/foreman-discovery-image-3.4.4-5.iso \
of=/dev/sdb

Insert the Discovery boot media into a bare metal host, start the host, and boot from the media. The Discovery Image displays an option for either Manual network setup or Discovery with DHCP:

After entering these details, select Next.

If you select Discovery with DHCP, the Discovery image requests only the primary network interface that connects to Foreman server. It attempts to automatically configure the network interface using a DHCP server, such as one that a Smart Proxy server provides.

After the primary interface configuration, the Discovery image requests the Server URL, which is the URL of Foreman server or Smart Proxy server offering the Discovery service. For example, to use the integrated Smart Proxy on Foreman server, use the following URL:

https://foreman.example.com:9090

Set the Connection type to Proxy, then select Next.

Optional: The Discovery image also provides a set of fields to input Custom facts for the Facter tool to relay back to Foreman server. These are entered in a name-value format. Provide any custom facts you require and select Confirm to continue.
