Installing docker, docker-compose on Raspberry Pi

Installed docker on raspberry pi 3b, OS version 11/bullseye. In the next post we will install pihole in docker.

Followed the link https://docs.docker.com/engine/install/raspberry-pi-os/

First we need to remove all unofficial packages, so type the following command. You may not have any packages installed, but let’s do it.

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; doneCode language: JavaScript (javascript)

There are different methods to install docker, but we will use docker’s apt repository method .

Install using apt repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker apt repository. Afterward, you can install and update Docker from the repository.

1.Setup docker’s apt repository

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/raspbian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/raspbian \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get updateCode language: PHP (php)

2. Install latest packages

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-pluginCode language: JavaScript (javascript)

3. Verify that the installation is successful by running the hello-world image:

sudo docker run hello-world

Uninstall docker, docker-compose

1. Uninstall docker engine, cli, containerd and docker compose packages

sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extrasCode language: JavaScript (javascript)

2.Remove directories where images, volumes and containers are stored

sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerdCode language: JavaScript (javascript)

3.Finally remove source keys and keyrings

sudo rm /etc/apt/sources.list.d/docker.list
sudo rm /etc/apt/keyrings/docker.ascCode language: PHP (php)
