Playbook

The DOCKER module has only one playbook: docker.yml to install docker daemon & docker compose on target node.

docker.yml

The raw playbook: docker.yml.

Run this playbook on any host will install docker-ce and docker-compose-plugin on target node with docker_enabled: true flag.

Here are the available subtasks in the docker.yml playbook:

• docker_install: Install Docker and Docker Compose packages on the node.
• docker_admin: Add specified users to the Docker administrator user group.
• docker_config: Generate Docker daemon service configuration file.
• docker_launch: Start the Docker daemon service.
• docker_register: Register Docker daemon as a Prometheus monitoring target.
• docker_image: Attempt to load prepackaged Docker images from /tmp/docker/*.tgz if present.

The Docker module does not provide a dedicated playbook for uninstalling Docker. If you need to uninstall Docker, you can manually stop the Docker service and then uninstall it:

systemctl stop docker                        # Stop Docker daemon service
yum remove docker-ce docker-compose-plugin   # Uninstall Docker on EL systems
apt remove docker-ce docker-compose-plugin   # Uninstall Docker on Debian systems
