How to write ansible play book to install docker and start docker container with docker image on multiple host machines

Answer 1

Hi@Shashi,

You can do this task easily with Ansible. First, update the Ansible inventory file in your controller node. After that, you need to create an Ansible playbook to configure the docker container. You can follow the below steps.

• Install the Docker container with the package module.

• Start the Docker service with the service module.

• Launch the container.

Hi@Shashi,

According to your requirement, you can use the below playbook. You may need to modify the software name depending on your O.S.

- hosts: localhost
  tasks:
  - name: Install docker.
    package:
      name: docker-ce
      state: present
  - name: Start docker service
    service:
      name: docker
      state: started
  - name: Create a redis container
    docker_container:
      name: data1
      image: centos
      state: started
      recreate: yes
      exposed_ports:
        - 8080
