Introduction

Docker is a platform for developing, shipping, and running applications in containers. Ansible is a powerful automation tool that can be used to manage and configure systems. In this guide, we'll walk through the steps to use Ansible to install and set up Docker on Ubuntu 22.04.

Prerequisites

Before proceeding, ensure you have:

1. An Ubuntu 22.04 server or desktop environment
2. Ansible installed on your local machine

Steps to Use Ansible to Install and Set Up Docker

1. Create Ansible Playbook: Create a new Ansible playbook to install Docker:

nano install_docker.yml

Add the following content to the playbook:

---
- hosts: all
  become: yes
  tasks:
    - name: Install Docker dependencies
      apt:
        name: ["apt-transport-https", "ca-certificates", "curl", "gnupg", "lsb-release"]

    - name: Add Docker GPG key
      apt_key:
        url: https://download.docker.com/linux/ubuntu/gpg
        state: present

    - name: Add Docker repository
      apt_repository:
        repo: deb [arch=amd64] https://download.docker.com/linux/ubuntu {{ ansible_lsb.codename }} stable

    - name: Install Docker
      apt:
        name: docker-ce
        state: present

1. Run Ansible Playbook: Run the Ansible playbook to install Docker:

ansible-playbook install_docker.yml

1. Verify Docker Installation: Verify that Docker has been installed successfully:

docker --version

Conclusion

Congratulations! You have successfully used Ansible to install and set up Docker on your Ubuntu 22.04 system. You can now start using Docker to develop and deploy containerized applications with ease.
