The `docker_edition` should be either `ce` (Community Edition) or `ee` (Enterprise Edition). You can also specify a specific version of Docker to install using the distribution-specific format: Red Hat/CentOS: `docker-{{ docker_edition }}-<VERSION>`; Debian/Ubuntu: `docker-{{ docker_edition }}=<VERSION>`. The `docker_edition` should be either `ce` (Community Edition) or `ee` (Enterprise Edition).
You can also specify a specific version of Docker to install using the distribution-specific format:
Red Hat/CentOS: `docker-{{ docker_edition }}-<VERSION>` (Note: you have to add this to all packages);
Debian/Ubuntu: `docker-{{ docker_edition }}=<VERSION>` (Note: you have to add this to all packages).
You can control whether the package is installed, uninstalled, or at the latest version by setting `docker_package_state` to `present`, `absent`, or `latest`, respectively. Note that the Docker daemon will be automatically restarted if the Docker package is updated. This is a side effect of flushing all handlers (running any of the handlers that have been notified by this and any other role up to this point in the play).
