community.docker.docker_image_load – Load docker image(s) from archives

Note

This plugin is part of the community.docker collection (version 1.10.2).

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.

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

New in version 1.3.0: of community.docker

Synopsis

• Load one or multiple Docker images from a .tar archive, and return information on the loaded image(s).

Requirements

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

• Docker API >= 1.23

• Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). This module does not work with docker-py.

• Docker SDK for Python >= 2.5.0

• Python >= 2.7

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 Docker SDK for Python 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_cert aliases: 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.
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: no ← (default) yes
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”
path path / required	The path to the .tar archive to load Docker image(s) from.
ssl_version string	Provide a valid SSL version number. Default value determined by ssl.py module. If the value is not specified in the task, the value of environment variable DOCKER_SSL_VERSION will be used instead.
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 yes 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: no ← (default) yes
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. The current default value is localhost. This default is deprecated and will change in community.docker 2.0.0 to be a value computed from docker_host. Explicitly specify localhost to make sure this value will still be used, and to disable the deprecation message which will be shown otherwise.
use_ssh_client boolean added in 1.5.0 of community.docker	For SSH transports, use the ssh CLI tool instead of paramiko. Requires Docker SDK for Python 4.4.0 or newer. Choices: no ← (default) yes
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: no ← (default) yes

Notes

Note

• Does not support check_mode.

• 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_SSL_VERSION, 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.

• 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 docker[tls] with ansible.builtin.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 $HOME/.docker/config.json if the DOCKER_CONFIG environment variable is not specified, and use $DOCKER_CONFIG/config.json otherwise.

• This module uses the Docker SDK for Python to communicate with the Docker daemon.

Examples

- name: Load all image(s) from the given tar file
  community.docker.docker_image_load:
    path: /path/to/images.tar
  register: result

- name: Print the loaded image names
  ansible.builtin.debug:
    msg: "Loaded the following images: {{ result.image_names | join(', ') }}"

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key	Description
image_names list / elements=string	List of image names and IDs loaded from the archive. Returned: success Sample: [“hello-world:latest”, “sha256:e004c2cc521c95383aebb1fb5893719aa7a8eae2e7a71f316a4410784edb00a9”]
