How to set up Docker on Raspberry Pi
Docker is a platform to develop, deploy, and run container apps. It’s gained popularity because it speeds up the development process and does not use a lot of resources when compared to virtual machines.
Let's first start by ensuring we have the latest updates by running the following command in the terminal.
sudo apt-get update && sudo apt-get upgrade
Run the following commands to install docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
Add permissions so that you don’t always have to use sudo.
sudo usermod -aG docker pi
Test that docker has been installed properly by running the following command:
docker run hello-world
Run the following steps in order to install docker-compose.
sudo apt-get install -y libffi-dev libssl-dev
sudo apt-get install -y python3 python3-pip
sudo apt-get remove python-configparser
sudo pip3 -v install docker-compose
It’s important to remember that because the Raspberry Pi uses the ARM architecture, it will not be compatible with all containers. Images need to be created from a base image of the ARM. These images can easily be found on the Docker Hub.
You are now ready to use Docker on your Raspberry Pi and use containers to build isolated and lightweight software.
