To see the hostname or use it in your playbook, you use the ansible_hostname or ansible_fqdn variables.

As Jonathan Cha’gara Lozada De La Matta mentioned, the hostname module can set it, but many applications still (incorrectly) rely on it also being in the /etc/hosts file. Here’s what I’ve done in my playbooks:

`

  • name: Setup hostname on system as {{ network_hostname }}.{{ network_dnsdomain }}
    hostname:
    name: “{{ network_hostname }}.{{ network_dnsdomain }}”

  • name: Add hostname to local /etc/hosts file
    lineinfile:
    dest: /etc/hosts
    state: present
    regexp: “^{{ network_ipaddr }}”
    line: “{{ network_ipaddr }} {{ network_hostname }}.{{ network_dnsdomain }} {{ network_hostname }}”
    `

In this case, I set network_* variables before calling this - my systems occasionally confuse Ansible and the ansible_hostname/ansible_fqdn are incorrect.

Thank you it’s working now.
