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.
