Example Playbook

This example is taken from molecule/default/converge.yml and is tested on each push, pull request and release.

---
- name: Converge
  hosts: all
  become: yes
  gather_facts: yes

  roles:
    - role: robertdebock.dns
      dns_port: 5353

The machine needs to be prepared. In CI this is done using molecule/default/prepare.yml:

---
- name: Prepare
  hosts: all
  gather_facts: no
  become: yes

  roles:
    - role: robertdebock.bootstrap
    - role: robertdebock.core_dependencies

Also see a full explanation and example on how to use these roles.
