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.
