Continuous Delivery with Docker and Jenkins

Running Docker containers

Running Docker containers is done with the use of the docker_container module and it looks very similar to what we presented for the Docker Compose configuration. Let's add it to the playbook.yml file.

- name: run Redis container  docker_container:    name: redis    image: redis    state: started    exposed_ports:    - 6379

You can read more about all of the options of the docker_container module on the official Ansible page at: https://docs.ansible.com/ansible/docker_container_module.html.

We can now execute the playbook to observe that Docker has been installed and the Redis container started. Note that it's a very convenient way of using Docker, since we don't need to manually install Docker engine on every machine.
