Docker is an open-source containerization platform that enables developers to package their applications along with all its dependencies into a standardized unit called a container. These containers can be easily moved from one environment to another, making it easier for developers to build, ship, and run applications. Raspberry Pi 4 is a popular single-board computer used for various projects in IoT, AI, and other fields. In this tutorial, we will learn how to install Docker on Raspberry Pi 4 and start using it to containerize your applications.

  1. Update Your System Before installing Docker, make sure your Raspberry Pi is up-to-date with the latest software packages by running the following commands in your terminal:
sudo apt update
sudo apt upgrade
  1. Install Docker Prerequisites Docker requires some prerequisite packages to be installed on your system. Run the following command to install them:
sudo apt install -y curl gnupg2 ca-certificates lsb-release software-properties-common
  1. Add Docker GPG Key Add Docker’s official GPG key using the following command:
curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
  1. Add Docker Repository Add the Docker repository to your system using the following command:
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
  1. Update Repository and Install Docker Update your repository and install the latest version of Docker using the following commands:
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io
  1. Check Docker Version Verify that Docker is successfully installed by checking its version using the following command:
docker --version
  1. Start and Enable Docker Service Start the Docker service and enable it to run at boot time using the following commands:
sudo systemctl start docker
sudo systemctl enable docker
  1. Test Your Docker Installation To test your Docker installation, pull a sample image from Docker Hub and run a container using the following commands:
docker pull hello-world
docker run hello-world

If everything is set up correctly, you should see a message indicating that the Docker container has been executed successfully.

That’s it! You have now installed Docker on your Raspberry Pi 4 and are ready to start using it for containerizing your applications. To learn more about how to use Docker, visit the official documentation. Happy containerizing!
