A StackOverflow question showed me that Ansible handlers can be stored in their own YAML file and included into any playbook to avoid repetition. You can create a
handler.yml file that is just a list of handlers, like:
- name: restart apache command: 'apachectl graceful' listen: 'apache conf change' - name: restart ssh service: name: ssh state: restarted
Then, in any given playbook, you can include and use them like:
- name: my playbook become: true handlers: - include: handlers.yml hosts: all tasks: - name: configure server name lineinfile: dest: /etc/apache2/apache2.conf line: 'ServerName tobymackenzie.com' regexp: '^ServerName.*$' state: present notify: 'apache conf change'
This simplifies things nicely if you reuse handlers in multiple playbooks. Roles sound like they make this even easier, but I haven’t switched to them yet.
