8.4. Ensuring the presence of A and PTR DNS records in IdM using Ansible

Procedure

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

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

2. Make a copy of the ensure-dnsrecord-with-reverse-is-present.yml Ansible playbook file. For example:

   $ cp ensure-dnsrecord-with-reverse-is-present.yml ensure-dnsrecord-with-reverse-is-present-copy.yml

3. Open the ensure-dnsrecord-with-reverse-is-present-copy.yml file for editing.

4. Adapt the file by setting the following variables in the freeipa.ansible_freeipa.ipadnsrecord task section:

   • Indicate that the value of the ipaadmin_password variable is defined in the secret.yml Ansible vault file.
   • Set the name variable to host1.
   • Set the zone_name variable to idm.example.com.
   • Set the ip_address variable to 192.168.122.45.

   • Set the create_reverse variable to true.

     This is the modified Ansible playbook file for the current example:

   ---
   - name: Ensure DNS Record is present.
     hosts: ipaserver
     become: true
     gather_facts: false
   
     tasks:
     # Ensure that dns record is present
     - freeipa.ansible_freeipa.ipadnsrecord:
         ipaadmin_password: "{{ ipaadmin_password }}"
         name: host1
         zone_name: idm.example.com
         ip_address: 192.168.122.45
         create_reverse: true
         state: present

5. Save the file.

   For details about variables and example playbooks in the FreeIPA Ansible collection, see the /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/README-dnsrecord.md file and the /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/playbooks/dnsrecord directory on the control node.

6. Run the playbook:

   $ ansible-playbook --vault-password-file=password_file -v -i inventory.file ensure-dnsrecord-with-reverse-is-present-copy.yml
