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
  name: Gather facts from all hosts
  tasks: []

- hosts: leader
  become: yes
  become_user: root
  vars:
    ansible_python_interpreter: /usr/bin/python3 # Force ansible to use python3 - Ubuntu doesn't ship with 2 by default
    swarm_enable: yes
    swarm_advertise_addr: "{{ansible_default_ipv4.address}}:2377"
  roles:
    - name: ansible-docker

- hosts: managers
  become: yes
  become_user: root
  vars:
    ansible_python_interpreter: /usr/bin/python3
    swarm_enable: yes
    swarm_join: yes
    swarm_advertise_addr: "{{ansible_default_ipv4.address}}:2377"
    swarm_join_host: "{{hostvars['leader']['ansible_default_ipv4']['address']}}"
    swarm_manager_join_token: "{{hostvars['leader']['swarm_manager_join_token']}}"
  roles:
    - name: ansible-docker

- hosts: workers
  become: yes
  become_user: root
  vars:
    ansible_python_interpreter: /usr/bin/python3
    swarm_enable: yes
    swarm_role: worker
    swarm_join: yes
    swarm_advertise_addr: "{{ansible_default_ipv4.address}}:2377"
    swarm_join_host: "{{hostvars['leader']['ansible_default_ipv4']['address']}}"
    swarm_worker_join_token: "{{hostvars['leader']['swarm_worker_join_token']}}"
