# These users will be added to the 'docker' group.
  - username: root
docker_yum_dependencies:
# These will be installed via yum
  - python-setuptools
  - python-pip
  - docker-compose
docker_pip_dependencies:
# These will be installed via pip (using the default python interpreter on your system)
  - docker
docker_firewalld: true # This enables the firewalld hack - set to false if not using firewalld.

• docker_composes
  • name: required, string, project name.
  • definition: required, dict, docker-compose definition
  • recreate: optional, [“always”, “never”, “smart”], recreate images when restarting - smart does so only if definition has changed, default smart

  • build: optional, boolean, forces a build of the docker image, default false
• docker_compose_files
