ansible.builtin.docker_image_facts (v2.7.16) — module

Inspect docker images

| "added in version" 2.1.0 of ansible.builtin"

Authors: Chris Houseknecht (@chouseknecht)

preview | supported by community

Install Ansible via `pip`

Install with pip install ansible==2.7.16

Description

Provide one or more image names, and the module will inspect each, returning an array of inspection results.

Requirements

python >= 2.6
docker-py >= 1.7.0
Please note that the L(docker-py,https://pypi.org/project/docker-py/) Python module has been superseded by L(docker,https://pypi.org/project/docker/) (see L(here,https://github.com/docker/docker-py/issues/1310) for details). For Python 2.6, C(docker-py) must be used. Otherwise, it is recommended to install the C(docker) Python module. Note that both modules should I(not) be installed at the same time. Also note that when both modules are installed and one of them is uninstalled, the other might no longer function and a reinstall of it is required.
Docker API >= 1.20

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 I(validate_certs) is set to C(yes) as well,
it will take precedence.
- If the value is not specified in the task, the value of environment variable C(DOCKER_TLS)
will be used instead. If the environment variable is not set, the default value
will be used.
type: bool

name:
description:
- An image name or a list of image names. Name format will be name[:tag] or repository/name[:tag],
where tag is optional. If a tag is not provided, 'latest' will be used.
required: true

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

ca_cert:
aliases:
- tls_ca_cert
- 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 C(DOCKER_CERT_PATH)
is set, the file C(ca.pem) from the directory specified in the environment variable
C(DOCKER_CERT_PATH) will 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 C(DOCKER_TIMEOUT)
will be used instead. If the environment variable is not set, the default value
will be used.
type: int

client_key:
aliases:
- tls_client_key
- key_path
description:
- Path to the client's TLS key file.
- If the value is not specified in the task and the environment variable C(DOCKER_CERT_PATH)
is set, the file C(key.pem) from the directory specified in the environment variable
C(DOCKER_CERT_PATH) will be used.
type: path

api_version:
aliases:
- docker_api_version
default: auto
description:
- 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 C(DOCKER_API_VERSION)
will be used instead. If the environment variable is not set, the default value
will be used.
type: str

client_cert:
aliases:
- tls_client_cert
- cert_path
description:
- Path to the client's TLS certificate file.
- If the value is not specified in the task and the environment variable C(DOCKER_CERT_PATH)
is set, the file C(cert.pem) from the directory specified in the environment variable
C(DOCKER_CERT_PATH) will be used.
type: path

docker_host:
aliases:
- docker_url
default: unix://var/run/docker.sock
description:
- 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, C(tcp://192.0.2.23:2376).
If TLS is used to encrypt the connection, the module will automatically replace
C(tcp) in the connection URL with C(https).
- If the value is not specified in the task, the value of environment variable C(DOCKER_HOST)
will be used instead. If the environment variable is not set, the default value
will be used.
type: str

ssl_version:
description:
- 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 C(DOCKER_SSL_VERSION)
will be used instead.
type: str

tls_hostname:
description:
- 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 C(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 C(localhost). This default is deprecated and will change
in community.docker 2.0.0 to be a value computed from I(docker_host). Explicitly
specify C(localhost) to make sure this value will still be used, and to disable
the deprecation message which will be shown otherwise.
type: str

use_ssh_client:
default: false
description:
- For SSH transports, use the C(ssh) CLI tool instead of paramiko.
- Requires Docker SDK for Python 4.4.0 or newer.
type: bool
version_added: 1.5.0
version_added_collection: community.docker

validate_certs:
aliases:
- tls_verify
default: false
description:
- 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 C(DOCKER_TLS_VERIFY)
will be used instead. If the environment variable is not set, the default value
will be used.
type: bool
