I know it looks crazy but to be honest I am frustrated of searching "install docker ubuntu" and copy paste lots of commands every time. If it happens for you a lot, you can bookmark this gist and just copy and paste it to install docker, compose and post installation commands.
for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done &&
sudo apt-get update &&
sudo apt-get install ca-certificates curl gnupg &&
sudo install -m 0755 -d /etc/apt/keyrings &&
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg &&
sudo chmod a+r /etc/apt/keyrings/docker.gpg &&
echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update &&
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin &&
sudo groupadd docker &&
sudo usermod -aG docker $USER &&
newgrp docker &&
sudo docker run hello-world
A shorter way
If you don't want to copy such a long command you can easily run this one:
/bin/bash -c "$(curl -s https://gist.githubusercontent.com/tuytoosh/b700f17f3ee3ad7f20d533e61de31c56/raw)"
It downloads the gist and runs the commands after getting root password.
You can write an Ansible playbook as well to do the same:
- name: Install Docker on Debian
hosts: all
become: true
tasks:
- name: Remove conflicting Docker packages
apt:
name: "{{ item }}"
state: absent
purge: true
loop:
- docker.io
- docker-doc
- docker-compose
- podman-docker
- containerd
- runc
ignore_errors: true
- name: Update apt repository cache
apt:
update_cache: yes
- name: Install prerequisite packages
apt:
name:
- ca-certificates
- curl
- gnupg
state: present
- name: Create keyrings directory for Docker
file:
path: /etc/apt/keyrings
state: directory
mode: '0755'
- name: Add Docker's official GPG key
ansible.builtin.command:
cmd: curl -fsSL https://download.docker.com/linux/debian/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
args:
creates: /etc/apt/keyrings/docker.gpg
- name: Set permissions for Docker GPG key
file:
path: /etc/apt/keyrings/docker.gpg
mode: '0644'
- name: Add Docker repository
ansible.builtin.apt_repository:
repo: "deb [arch={{ ansible_architecture }} signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian {{ ansible_lsb.codename }} stable"
filename: docker
- name: Update apt cache after adding Docker repo
apt:
update_cache: yes
- name: Install Docker packages
apt:
name:
- docker-ce
- docker-ce-cli
- containerd.io
- docker-buildx-plugin
- docker-compose-plugin
state: present
- name: Create Docker group if it does not exist
group:
name: docker
state: present
- name: Add user to Docker group
user:
name: "{{ ansible_user }}"
groups: docker
append: yes
- name: Run Docker hello-world to verify installation
command: docker run hello-world
register: docker_test_result
failed_when: docker_test_result.rc != 0
