+

api_version

+

aliases: docker_api_version

+

string

+

The version of the Docker API running on the Docker Host.

+

Defaults to the latest version of the API supported by this collection and the docker daemon.

+

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

+

Default: "auto"

+
+
+
+
+

ca_path

+

aliases: ca_cert, tls_ca_cert, cacert_path

+

path

+

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 DOCKER_CERT_PATH is set, the file ca.pem from the directory specified in the environment variable DOCKER_CERT_PATH will be used.

+

This option was called ca_cert and got renamed to ca_path in community.docker 3.6.0. The old name has been added as an alias and can still be used.

+
+
+
+

client_cert

+

aliases: tls_client_cert, cert_path

+

path

+

Path to the client’s TLS certificate file.

+

If the value is not specified in the task and the environment variable DOCKER_CERT_PATH is set, the file cert.pem from the directory specified in the environment variable DOCKER_CERT_PATH will be used.

+
+
+
+

client_key

+

aliases: tls_client_key, key_path

+

path

+

Path to the client’s TLS key file.

+

If the value is not specified in the task and the environment variable DOCKER_CERT_PATH is set, the file key.pem from the directory specified in the environment variable DOCKER_CERT_PATH will be used.

+

aliases: docker_url

+

string

+

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, tcp://192.0.2.23:2376. If TLS is used to encrypt the connection, the module will automatically replace tcp in the connection URL with https.

+

If the value is not specified in the task, the value of environment variable DOCKER_HOST will be used instead. If the environment variable is not set, the default value will be used.

+

Default: "unix:///var/run/docker.sock"

path

+

Default: 60

+
+

tls

+

boolean

+

Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if validate_certs is set to true as well, it will take precedence.
