Notes

Note

• Images will only resolve to the latest digest when using Docker API >= 1.30 and Docker SDK for Python >= 3.2.0. When using older versions use force_update: true to trigger the swarm to resolve a new image.
• 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://docker-py.readthedocs.io/en/stable/machine/ 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 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.

Return Values

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

Key	Returned	Description
changes list	always	List of changed service attributes if a service has been altered, [] otherwise. Sample: ['container_labels', 'replicas']
rebuilt boolean	always	True if the service has been recreated (removed and created) Sample: True
swarm_service dictionary	always	Dictionary of variables representing the current state of the service. Matches the module parameters format. Note that facts are not part of registered vars but accessible directly. Note that before Ansible 2.7.9, the return variable was documented as ansible_swarm_service, while the module actually returned a variable called ansible_docker_service. The variable was renamed to swarm_service in both code and documentation for Ansible 2.7.9 and Ansible 2.8.0. In Ansible 2.7.x, the old name ansible_docker_service can still be used.
