11.2. Configuring the Satellite Capsule Server Discovery Plug-in

download PDF
Ensure the foreman_url setting exists in the Satellite Capsule Server configuration file. The setting can appear as follows:
# grep foreman_url /etc/foreman-proxy/settings.yml
The satellite-installer command configures this variable automatically, but Red Hat recommends that you check that the host responds correctly and there are no firewall rules blocking communication.

11.2.1. Configuring Discovery Subnets

You need to configure all subnets with discovered hosts to communicate through the Satellite Capsule Server. In the Satellite web UI, navigate to Infrastructure Subnets and select the required Capsule Server for each subnet that needs to perform host discovery and ensure it is connected to the Discovery Capsule Server.
To verify that a Capsule Server has the Discovery plug-in enabled, navigate to Infrastructure Capsules. The Discovery plug-in should appear in the list of features associated with the Capsule Server. Click Refresh features to ensure that the list is up-to-date.

11.2.2. Using Hammer with the Discovery Plug-in

To use the hammer command with the Discovery plug-in, you need to enable the Discovery plug-in in /etc/hammer/cli.modules.d/foreman_discovery.yml as follows:
  :enable_module: true
See hammer configuration directories[5] for more information about the files and directories that hammer uses.

11.2.3. Reviewing User Permissions

When it first starts, the Satellite Capsule Server Discovery plug-in creates a role called Discovery. You can assign this role to non-administrative users to allow them to use the Discovery plug-in. Alternatively, assign the perform_discovery permission to an existing role. For more information on roles and permissions, see Creating and Managing Users in the Server Administration Guide.
