      - By default environment files are loaded from a C(.env) file located directly under the O(project_src) directory.
      - O(env_files) can be used to specify the path of one or multiple custom environment files instead.
      - The path is relative to the O(project_src) directory.

  state:
    description:
      - Desired state of the project.
      - V(present) is equivalent to running C(docker compose up).

  pull:
    description:
      - Whether to pull images before running. This is used when C(docker compose up) is ran.
      - V(always) ensures that the images are always pulled, even when already present on the Docker daemon.
      - V(missing) only pulls them when they are not present on the Docker daemon.
      - V(never) never pulls images. If they are not present, the module will fail when trying to create the containers that need them.
      - V(policy) use the C(pull_policy) defined for the service to figure out what to do.

    type: bool
    default: true
  recreate:
    description:
      - By default containers will be recreated when their configuration differs from the service definition.
      - Setting to V(never) ignores configuration differences and leaves existing containers unchanged.
      - Setting to V(always) forces recreation of all existing containers.

requirements:
  - "Docker CLI with Docker compose plugin 2.18.0 or later"

author:
  - Felix Fontein (@felixfontein)

notes:
  - |-
    The Docker compose CLI plugin has no stable output format (see for example U(https://github.com/docker/compose/issues/10872)),
    and for the main operations also no machine friendly output format. The module tries to accomodate this with various
    version-dependent behavior adjustments and with testing older and newer versions of the Docker compose CLI plugin.

    Currently the module is tested with multiple plugin versions between 2.18.1 and 2.23.3. The exact list of plugin versions
    will change over time. New releases of the Docker compose CLI plugin can break this module at any time.
