ansible.builtin.docker_login (v2.6.0) — module

Log into a Docker registry.

| "added in version" 2.0 of ansible.builtin"

Install Ansible via pip

Install with pip install ansible==2.6.0

Description

Provides functionality similar to the "docker login" command.

Authenticate with a docker registry and add the credentials to your local Docker config file. Adding the credentials to the config files allows future connections to the registry using tools such as Ansible's Docker modules, the Docker CLI and docker-py without needing to provide credentials.

Running in check mode will perform the authentication without updating the config file.

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(true) 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

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

email:
    description:
    - 'The email address for the registry account. NOTE: private registries may not require
      this, but Docker Hub requires it.'
    required: false

state:
    choices:
    - present
    - absent
    default: present
    description:
    - This controls the current state of the user. C(present) will login in a user, C(absent)
      will log them out.
    - To logout you only need the registry server, which defaults to DockerHub.
    - Before 2.1 you could ONLY log in.
    - docker does not support 'logout' with a custom config file.

      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.
