Note that private registries usually don't need this, but if you want to log into your Docker Hub account (default behaviour) you need to specify this in order to be able to log in. - required: false - default: None - reauth: - description: - - Whether refresh existing authentication on the Docker server (boolean) - required: false - default: false - dockercfg_path: - description: - - Use a custom path for the .dockercfg file - required: false - default: ~/.docker/config.json - docker_url: - description: - - Refers to the protocol+hostname+port where the Docker server is hosted - required: false - default: unix://var/run/docker.sock - timeout: - description: - - The HTTP request timeout in seconds - required: false - default: 600 - -requirements: [ "python >= 2.6", "docker-py >= 1.1.0" ] -''' - -EXAMPLES = ''' -Login to a Docker registry without performing any other action.
