22.10. Unregistering a system by using the rhc RHEL system role

Procedure

1. Create a playbook file, for example, ~/playbook.yml, with the following content:

   ---
   - name: Managing systems with the rhc RHEL system role
     hosts: managed-node-01.example.com
     tasks:
       - name: Unregister the system
         ansible.builtin.include_role:
           name: redhat.rhel_system_roles.rhc
         vars:
           rhc_state: absent

   The settings specified in the example playbook include the following:

   rhc_state: absent

   Specifies the system should be unregistered from the registration server, RHSM, or Satellite.

   For details about all variables used in the playbook, see the /usr/share/ansible/roles/rhel-system-roles.rhc/README.md file on the control node.

2. Validate the playbook syntax:

   $ ansible-playbook --syntax-check ~/playbook.yml

   Note that this command only validates the syntax and does not protect against a wrong but valid configuration.

3. Run the playbook:

   $ ansible-playbook ~/playbook.yml
