How to install Docker and Docker Compose on Raspberry Pi 4

This blog post describes how to install Docker and docker-compose on Raspberry Pi 4. In short, to install docker and docker-compose we need to make sure that our system is up to date, install required dependencies, and install docker with docker-compose. Also, we can add our user to the docker group to run docker without sudo.

Make sure system is up to date

sudo apt update && sudo apt upgrade -y

Install required dependencies

sudo apt install python3 python3-pip libffi-dev libssl-dev -y

Install Docker

curl -sSL https://get.docker.com | sh

Add current user to the docker group

sudo usermod -aG docker `whoami`

In order changes to be applied, we need either to re-login or to reboot the system.

Install docker-compose

Now we’re ready to install docker-compose by running

sudo pip3 -v install docker-compose

Verify everything installed and works correctly

docker run hello-world

The output will look like:

For docker-compose verifications we can create the following docker-compose.yml file with the following content:

version: '3'

services:
  hello:
    image: hello-world
    restart: always
    container_name: hello-world

and run the command:

docker-compose up

The output will look like:
