            - The URL or Unix socket path used to connect to the Docker API. To connect to a remote host, provide the
              TCP connection string. For example, C(tcp://192.0.2.23:2376). If TLS is used to encrypt the connection,
              the module will automatically replace C(tcp) in the connection URL with C(https).

              instead. If the environment variable is not set, the default value will be used.

            - Defaults to the latest version of the API supported by Docker SDK for Python and the docker daemon.
            - If the value is not specified in the task, the value of environment variable C(DOCKER_API_VERSION) will be
              used instead. If the environment variable is not set, the default value will be used.

        description:
            - Secure the connection to the API by using TLS without verifying the authenticity of the Docker host
              server. Note that if I(validate_certs) is set to C(yes) as well, it will take precedence.
            - If the value is not specified in the task, the value of environment variable C(DOCKER_TLS) will be used

notes:
  - Connect to the Docker daemon by providing parameters with each task or by defining environment variables.
    You can define C(DOCKER_HOST), C(DOCKER_TLS_HOSTNAME), C(DOCKER_API_VERSION), C(DOCKER_CERT_PATH), C(DOCKER_SSL_VERSION),
    C(DOCKER_TLS), C(DOCKER_TLS_VERIFY) and C(DOCKER_TIMEOUT). If you are using docker machine, run the script shipped
    with the product that sets up the environment. It will set these variables for you. See
    U(https://docs.docker.com/machine/reference/env/) for more details.
  - When connecting to Docker daemon with TLS, you might need to install additional Python packages.
    For the Docker SDK for Python, version 2.4 or newer, this can be done by installing C(docker[tls]) with M(pip).
  - Note that the Docker SDK for Python only allows to specify the path to the Docker configuration for very few functions.
    In general, it will use C($HOME/.docker/config.json) if the C(DOCKER_CONFIG) environment variable is not specified,
    and use C($DOCKER_CONFIG/config.json) otherwise.
