6.10. Ensuring a DNS Forward Zone is disabled in IdM using Ansible

Procedure

1. Navigate to the /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/playbooks/dnsconfig directory:

   $ cd /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/playbooks/dnsconfig

2. Make a copy of the forwarders-absent.yml Ansible playbook file. For example:

   $ cp forwarders-absent.yml ensure-disabled-forwardzone.yml

3. Open the ensure-disabled-forwardzone.yml file for editing.

4. Adapt the file by setting the following variables:

   1. Change the name variable for the playbook to Playbook to ensure a dnsforwardzone is disabled in IdM DNS.
   2. In the tasks section, change the name of the task to Ensure a dnsforwardzone for example.com is disabled.
   3. In the tasks section, change the freeipa.ansible_freeipa.ipadnsconfig heading to freeipa.ansible_freeipa.ipadnsforwardzone.

   4. In the freeipa.ansible_freeipa.ipadnsforwardzone section:

      1. Indicate that the value of the ipaadmin_password variable is defined in the secret.yml Ansible vault file.
      2. Add the name variable and set it to example.com.
      3. Remove the entire forwarders section.
      4. Change the state variable to disabled.

      This the modified Ansible playbook file for the current example:

   ---
   - name: Playbook to ensure a dnsforwardzone is disabled in IdM DNS
     hosts: ipaserver
   
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
     tasks:
     - name: Ensure a dnsforwardzone for example.com is disabled
     freeipa.ansible_freeipa.ipadnsforwardzone:
         ipaadmin_password: "{{ ipaadmin_password }}"
         name: example.com
         state: disabled

5. Save the file.

   For details about all variables used in the playbook, see the /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/README-dnsforwardzone.md file on the control node.

6. Run the playbook:

   $ ansible-playbook --vault-password-file=password_file -v -i inventory.file ensure-disabled-forwardzone.yml
