Inputs

    
tls:
    default: false
    description:
    - Secure the connection to the API by using TLS without verifying the authenticity
      of the Docker host server. Note that if O(validate_certs) is set to V(true) as well,
      it will take precedence.
    - If the value is not specified in the task, the value of environment variable E(DOCKER_TLS)
      will be used instead. If the environment variable is not set, the default value
      will be used.
    type: bool

debug:
    default: false
    description:
    - Debug mode
    type: bool

images:
    default: false
    description:

    type: bool

ca_path:

    - cacert_path
    description:
    - Use a CA certificate when performing server verification by providing the path to
      a CA certificate file.
    - If the value is not specified in the task and the environment variable E(DOCKER_CERT_PATH)
      is set, the file C(ca.pem) from the directory specified in the environment variable
      E(DOCKER_CERT_PATH) will be used.
    - This option was called O(ca_cert) and got renamed to O(ca_path) in community.docker
      3.6.0. The old name has been added as an alias and can still be used.
    type: path

timeout:
    default: 60
    description:
    - The maximum amount of time in seconds to wait on a response from the API.
    - If the value is not specified in the task, the value of environment variable E(DOCKER_TIMEOUT)
      will be used instead. If the environment variable is not set, the default value
      will be used.

      daemon.
    - If the value is not specified in the task, the value of environment variable E(DOCKER_API_VERSION)
      will be used instead. If the environment variable is not set, the default value

    type: str

client_cert:
    aliases:
