Install Docker and Docker-Compose with Ansible on Ubuntu

04 Jan 2022DevOps Ansible

I made some changes from what I could see elsewhere blog posts. So here's my version of the installation of docker and docker-compose via ansible playbook.

don't loop for installation package, it seems to take a long time wiht update_cache on.
Installation of docker-compose
set some users to the docker group.
add the repository with gathering facts, no need to specify the ubuntu distribution.

repo: deb https://download.docker.com/linux/ubuntu {{ ansible_distribution_release }} stable

- hosts: docker
  become: true
  tasks:
    - name: install dependencies
      apt:
        name:
          - apt-transport-https
          - ca-certificates
          - curl
          - gnupg-agent
          - software-properties-common
        state: latest
        update_cache: yes
    - name: GPG key
      apt_key:
        url: https://download.docker.com/linux/ubuntu/gpg
        state: present
    - name: repository docker
      apt_repository:
        repo: deb https://download.docker.com/linux/ubuntu {{ ansible_distribution_release }} stable
        state: present
    - name: install docker
      apt:
        name:
          - docker-ce
          - docker-ce-cli
          - containerd.io
        state: latest
        update_cache: yes
    - name: adding users to group docker
      user:
        name: '{{ item }}'
        groups: docker
        append: yes
      loop:
        - user1
        - user2
    - name: Install docker-compose
      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'

That's all, apply the following script with ansible-playbook.
