Chapter 4. Applying Ansible definitions to hosts

When a host has one or more Ansible roles assigned to it, Satellite can run the roles on the host to apply and enforce the configuration state that the roles define.

4.1. Running Ansible roles on a host
Copy link

Run Ansible roles on a host through the Satellite web UI to apply the assigned configuration immediately. This helps you verify and enforce the intended state of the host.

Prerequisites

Procedure

  1. In the Satellite web UI, navigate to Hosts > All Hosts.
  2. Select the host on which you want to run the assigned Ansible roles.
  3. From the Schedule a job menu, select Run Ansible roles.

Verification

  • You can view the status of your Ansible job by navigating to Monitor > Jobs.

4.2. Running Ansible roles on a host group
Copy link

When a host group has one or more Ansible roles assigned to it, Satellite can run the roles on all hosts in the host group at once to apply and enforce the configuration state that the roles define.

Prerequisites

Procedure

  1. In the Satellite web UI, navigate to Configure > Host Groups.
  2. From the list in the Actions column for the host group, select Run all Ansible roles.
  3. You can view the status of your Ansible job on the Run Ansible roles page. Click Rerun to rerun a job.

Run Ansible roles in check mode through the Satellite web UI to preview changes before applying them. This helps you reduce risk when validating role behavior on a host.

Procedure

  1. In the Satellite web UI, navigate to Hosts > All Hosts.
  2. Click Edit for the host you want to enable check mode for.
  3. In the Parameters tab, ensure that the host has a parameter named ansible_roles_check_mode with type boolean set to true.
  4. Click Submit.
