Long time no see, now i will show you how to install Docker using Ansible Playbook. Let's start!!!
Setup
First, you need to install Ansible. Just follow this link to install Ansible on your operating system installation guide.
After installation, create new directory called ansible-docker.
$ mkdir ansible-docker && cd ansible-docker
Create a new file called ansible.cfg as the Ansible configuration setting and then define the inventory file.
[defaults]
inventory = hosts
host_key_checking = True
deprecation_warnings = False
collections = ansible.posix, community.general
Then create a new file called hosts, where the name is defined on ansible.cfg.
[example-server]
0.0.0.0 ansible_user=root
NB: Don't forget to change the IP Address and host name.
After setup the Ansible configuration setting & inventory file, let's create a YAML called playbook.yml
---
- name: Setup Docker on Ubuntu Server 22.04
hosts: all
become: true
remote_user: root
roles:
- config
- docker
Then create roles directory:
- Config, On this directory I will create a directory called tasks. After that, I should create yaml file called
main.ymlto run update, upgrade & install many dependencies.
---
- name: Update&Upgrade
ansible.builtin.apt:
name: aptitude
state: present
update_cache: true
- name: Install dependencies
ansible.builtin.apt:
name:
- net-tools
- apt-transport-https
- ca-certificates
- curl
- software-properties-common
- python3-pip
- virtualenv
- python3-setuptools
- gnupg-agent
- autoconf
- dpkg-dev
- file
- g++
- gcc
- libc-dev
- make
- pkg-config
- re2c
- wget
state: present
update_cache: true
- Docker, On this directory create 2 directories called
tasks&templates.
On tasks directory create new file called main.yml. This file contains Docker installation, Docker Compose installation & private registry setup.
---
- name: Add Docker GPG apt Key
ansible.builtin.apt_key:
url: https://download.docker.com/linux/ubuntu/gpg
state: present
- name: Add repository into sources list
ansible.builtin.apt_repository:
repo: deb [arch=amd64] https://download.docker.com/linux/ubuntu {{ ansible_lsb.codename }} stable
state: present
filename: docker
- name: Install Docker 23.0.1-1
ansible.builtin.apt:
name:
- docker-ce=5:23.0.1-1~ubuntu.22.04~jammy
- docker-ce-cli=5:23.0.1-1~ubuntu.22.04~jammy
- containerd.io
state: present
update_cache: true
- name: Setup docker user
ansible.builtin.user:
name: docker
groups: "docker"
append: true
sudo_user: yes
- name: Install Docker module for Python
ansible.builtin.pip:
name: docker
- name: Install Docker-Compose&Set Permission
ansible.builtin.get_url:
url: https://github.com/docker/compose/releases/download/1.29.2/docker-compose-Linux-x86_64
dest: /usr/local/bin/docker-compose
mode: '755'
- name: Create Docker-Compose symlink
ansible.builtin.command:
cmd: ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
creates: /usr/bin/docker-compose
- name: Add private registry
ansible.builtin.template:
src: daemon.j2
dest: /etc/docker/daemon.json
mode: preserve
- name: Restart Docker
ansible.builtin.service:
name: docker
state: restarted
enabled: true
In the template, create a template file using a jinja file named daemon.j2. This file contains configuration for private registry settings (optional).
{
"insecure-registries" : ["http://0.0.0.0:5000"]
}
NB: Field the IP using your remote server private IP
After all setup, Your project directory should look like this:
$ tree
.
├── ansible.cfg
├── config
│ └── tasks
│ └── main.yml
├── docker
│ ├── tasks
│ │ └── main.yml
│ └── templates
│ └── daemon.j2
├── hosts
└── playbook.yml
Test & Run
Okay, now test Your playbook.yml file using this command.
$ ansible-playbook --syntax-check playbook.yml
If You don't have any errors, run the playbook using this command.
$ ansible-playbook -i hosts playbook.yml
Output, wait until finish.

Conclusion
In this post, I just show you how to install Docker in a specific version using Ansible Playbook when you have one or more servers.
Thank You for reading this post, If You have suggestions or questions please leave them below. Thanks
NB: In this case, I just set the user as root. I installed the Docker on Ubuntu Server 22.04. For full code follow this link ansible-docker.
