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: true
  gather_facts: true

  become: true
  gather_facts: false

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