Example Playbook

- hosts: centos7
  roles:
  - role: forge.docker
    docker_daemon_config:
      live-restore: true
      storage-driver: overlay2
      storage-opts:
        - 'overlay2.override_kernel_check=true'

Restart vs reload

The docker daemon is reloaded after every configuration change to ensure the containers keep running. Because of this major options like the storage driver will not be activated on reload. If you need the daemon to restart set -e "docker_restart=true".

Tests

Tests are processed with molecule. To run the tests from the cli type molecule test --all.
