So if it’s not done already, follow one of these tutorials to get your system ready: I’m testing this tutorial for you on a Raspberry Pi 4 with Raspberry Pi OS Bullseye, but it should be the same steps for whatever system you use. Arch Linux has an experimental version available too. On their website, they say that Ubuntu, Debian, and Fedora are supported, so I guess it should work on any variation of these systems. Install an operating systemĭocker is supported on almost any Linux distribution. Docker runs as a service, so we need to install it before creating any container. The user will download the image, and create a container from it, making sure everything will be installed and will run as expected by the developer.īefore using Docker on your Raspberry Pi, there are a few things to install first. The developer will basically create an image of its own system, including everything needed for the main application to run, and share it with the end-user. Instead of installing each piece of software individually on your system, with many dependencies and regular headaches when you install a complex application, Docker will create a container, a separate sub-system on your system, with everything required for the application. In simple words, Docker is like the next generation of the Debian package manager (APT). The first third of the book teaches you the basics, but the following chapters include projects you can try on your own. It’s a 30-day challenge, where you learn one new thing every day until you become a Raspberry Pi expert. If you are looking to quickly progress on Raspberry Pi, you can check out my e-book here.

I’ll use Raspberry Pi OS, but the idea is the same with any operating system. I will start with a brief introduction to Docker, and then show you how to install and use it on a Raspberry Pi.

The main benefits of Docker are the ease of deployment, security, and scalability. If you are a bit lost with this technology, you are at the perfect place to learn everything you need to know about Docker.ĭocker is a piece of software that allows you to install and run software in separate containers, by virtualizing the running operating system. I was a system administrator, and containers weren’t used at all when I started, so that’s pretty new too. I noticed that more and more projects have an option to install the main software parts with Docker, but I guess it’s not always clear for everyone what we are talking about.
