Example Playbook

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

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

  vars:
    dhcpd_subnets:
      - network: "{{ ansible_default_ipv4.network }}"
        netmask: 255.255.255.0

  roles:
    - role: robertdebock.dhcpd

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

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

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

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