23.3. Deploying an SELinux module by using the selinux RHEL system role

Procedure

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

   ---
   - name: Managing SELinux
     hosts: managed-node-01.example.com
     tasks:
       - name: Deploying a SELinux module
         ansible.builtin.include_role:
           name: redhat.rhel_system_roles.selinux
         vars:
           selinux_modules:
             - path: <module_file>
   	    priority: <value>
               state: enabled

   The settings specified in the example playbook include the following:

   path: <module_file>

   Sets the path to the module file on the control node.

   priority: <value>

   Sets the SELinux module priority. 400 is the default.

   state: <value>

   Defines the state of the module:

   • enabled: Install or enable the module.
   • disabled: Disable a module.
   • absent: Remove a module.

   For details about all variables used in the playbook, see the /usr/share/ansible/roles/rhel-system-roles.selinux/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
