Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

  ---
  - hosts: all
    gather_facts: true
    become: yes
    become_user: root
    become_method: sudo
    roles:
      - { role: enr0s.ansible_role_bootstrap }
      - { role: enr0s.ansible_role_docker } 
      - { role: ansible-role-k8s }
