How to use Ansible with Docker?

Ansible is a powerful automation tool that can be used with Kubernetes to simplify the management and configuration of your cluster. By following a few simple steps, you can use Ansible to define the desired state of your Kubernetes resources and automate tasks such as deployment, scaling, and configuration updates. This integration allows for efficient and streamlined management of your Kubernetes environment.

Using Ansible with Docker: A Step-by-Step Guide

  1. Install Ansible: Follow OS-specific installation instructions from the Ansible documentation.
  2. Set up Inventory: Create inventory.yml defining Docker hosts. Example:

         [docker_hosts]
host1
host2

3. Configure SSH Access: Update ~/.ssh/config for SSH access to Docker hosts.

Example:

Host host1
 Hostname <host1-IP-or-hostname>
 User <username>
 IdentityFile ~/.ssh/id_rsa

Host host2
 Hostname <host2-IP-or-hostname>
 User <username>
 IdentityFile ~/.ssh/id_rsa

4. Create Playbook: Make docker.yml for Docker management tasks.

Example:

---
- hosts: docker_hosts
 become: true
 tasks:
   - name: Install Docker
     apt:
       name: docker.io
       state: present
       update_cache: yes
     become: true

   - name: Start Docker service
     service:
       name: docker
       state: started

5. Run Ansible Playbook: Execute in terminal:

$ ansible-playbook -i inventory.yml docker.yml

  1. Ansible connects to hosts, installs Docker, and starts the Docker service.

Extend the playbook for advanced Docker management. Refer to Ansible documentation for Docker modules.
