community.docker.docker_image_tag module – Tag Docker images with new names and/or tags

Note

This module is part of the community.docker collection (version 4.0.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.docker. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.docker.docker_image_tag.

New in community.docker 3.6.0

Synopsis

• This module allows to tag Docker images with new names and/or tags.

Requirements

The below requirements are needed on the host that executes this module.

• Docker API >= 1.25

• backports.ssl_match_hostname (when using TLS on Python 2)

• paramiko (when using SSH with use_ssh_client=false)

• pyOpenSSL (when using TLS)

• pywin32 (when using named pipes on Windows 32)

• requests

Parameters

Parameter	Comments
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.
debug boolean	Debug mode Choices: false ← (default) true
docker_host 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"
existing_images string	Defines the behavior if the image to be tagged already exists and is another image than the one identified by name and tag. If set to keep, the tagged image is kept. If set to overwrite, the tagged image is overwritten by the specified one. Choices: "keep" "overwrite" ← (default)
name string / required	Image name. Name format will be one of: name, repository/name, registry_server:port/name. When pushing or pulling an image the name can optionally include the tag by appending :tag_name. Note that image IDs (hashes) can also be used.
repository list / elements=string / required	List of new image names to tag the image as. Expects format repository:tag. If no tag is provided, will use the value of the tag parameter if present, or latest.
tag string	Tag for the image name name that is to be tagged. If name‘s format is name:tag, then the tag value from name will take precedence. Default: "latest"
timeout integer	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 DOCKER_TIMEOUT will be used instead. If the environment variable is not set, the default value will be used. 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. If the value is not specified in the task, the value of environment variable DOCKER_TLS will be used instead. If the environment variable is not set, the default value will be used. Choices: false ← (default) true
tls_hostname string	When verifying the authenticity of the Docker Host server, provide the expected name of the server. If the value is not specified in the task, the value of environment variable DOCKER_TLS_HOSTNAME will be used instead. If the environment variable is not set, the default value will be used. Note that this option had a default value localhost in older versions. It was removed in community.docker 3.0.0.
use_ssh_client boolean added in community.docker 1.5.0	For SSH transports, use the ssh CLI tool instead of paramiko. Choices: false ← (default) true
validate_certs aliases: tls_verify boolean	Secure the connection to the API by using TLS and verifying the authenticity of the Docker host server. If the value is not specified in the task, the value of environment variable DOCKER_TLS_VERIFY will be used instead. If the environment variable is not set, the default value will be used. Choices: false ← (default) true

Attributes

Attribute	Support	Description
action_group	Action groups: community.docker.docker, docker	Use group/docker or group/community.docker.docker in module_defaults to set defaults for this module.
check_mode	Support: full	Can run in check_mode and return changed status prediction without modifying target.
diff_mode	Support: full	Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

Notes

Note

• Connect to the Docker daemon by providing parameters with each task or by defining environment variables. You can define DOCKER_HOST, DOCKER_TLS_HOSTNAME, DOCKER_API_VERSION, DOCKER_CERT_PATH, DOCKER_TLS, DOCKER_TLS_VERIFY and 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 https://docs.docker.com/machine/reference/env/ for more details.

• This module does not use the Docker SDK for Python to communicate with the Docker daemon. It uses code derived from the Docker SDK or Python that is included in this collection.
