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

Note

This module is part of the community.docker collection (version 3.7.0).

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_load.

New in community.docker 1.3.0

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 >= 1.25

  • 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"

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 Python 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 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
