I found a popular role in Ansible Galaxy with a ton of installs, but the documentation that comes with it doesn’t work, which is fine… not a supported version, etc. I used the steps below to get it working.

Please be aware, the test branch is likely not stable, and shouldn’t be used for production. Follow this at your own risk.

1.) Run the command below to install the role

root@server:~$ ansible-galaxy install geerlingguy.docker

2.) Create a text file named “install-docker.yml”
  – The value assigned to docker_apt_release_channel being “test”.
  – Add your own username(s) under “docker_users”
(This yaml file is located on my github page here: https://github.com/jonhowe/Virtjunkie.com/blob/master/install-docker.yml)

---
- name: Install Docker
  hosts: all
  become: yes
  become_method: sudo
  tasks:
  - name: Install Docker and docker-compose
    include_role:
       name: geerlingguy.docker
    vars:
       - docker_edition: 'ce'
       - docker_apt_release_channel: test
       - docker_package_state: present
       - docker_install_compose: true
       - docker_compose_version: "1.22.0"
       - docker_users:
          - jhowe

3.) Then it’s as easy as running the playbook

root@server:~$ ansible-playbook -K install-docker.yml
