This role installs Docker and optional sets up a user for sudo-less usage.

To install run ansible-galaxy install sansible.docker or add this to your roles.yml.

- name: sansible.docker
  version: v3.0.x

and run ansible-galaxy install -p ./roles -r roles.yml

This role uses tags: build and configure

• build - Installs Docker and supporting tools
• configure - Configures Docker Daemon

Simply include this role in your playbook, options for Docker's daemon.json file can be specified via the sansible_docker_daemon_config variable:

- name: Install and configure docker
  hosts: "somehost"

  roles:
    - role: sansible.docker
      sansible_docker_daemon_config:
        bip: 10.8.0.0/25
        storage-driver: overlay2

Setup user for sudo-less access:

- name: Install and configure docker
  hosts: "somehost"

  roles:
    - role: sansible.docker
      sansible_docker_workspace_user: some_user

Note that if you want to make use of Docker via this user within the same Ansible run then you will need to be aware of this issue: https://github.com/ansible/ansible-modules-core/issues/921.

This role supports DeviceMapper via LVM as well:

- name: Install and configure docker
  hosts: "somehost"

  roles:
    - role: sansible.docker
      storage-driver: devicemapper
      storage-opts:
        - "dm.directlvm_device=/dev/sdb"
