--- upgrade: - | When enabled, a Docker Registry is now deployed on hosts in the ``docker-registry`` group, which defaults to include the seed. The existing behaviour of deploying on the first controller can be retained by removing the seed group from ``[docker-registry:children]`` in ``$KAYOBE_CONFIG_PATH/inventory/groups`` and creating a ``[docker-registry]`` group including the name of the first controller. - | Modifies the default value of ``docker_registry_image`` variable to not use a private registry in the image name by default. This avoids a potential circular dependency during deployment of the registry container.
