So, Docker can be a perfect candidate for web app development and testing on Raspberry Pi. Of course, you can do other things like running a web server, proxy server or a database server etc. On Docker on Raspberry Pi single board computer. In this article, I am going to show you how to install Docker on Raspbian OS that runs on Raspberry Pi. The best way to install Docker is to fetch it from the official Docker repositories, so to ensure that you’re always running the latest version. To install Docker CE on Raspberry Pi OS, both 32-bit and 64-bit, run.
Install Docker on Raspberry Pi # Installing Docker on Raspberry Pi is just a matter of running a few commands. First, download the Docker installation script using the following curl command: curl -fsSL -o get-docker.sh. Once the download is complete, execute the script by typing: sh get-docker.sh. I decided to give it a try on the Raspberry Pi since Pi-hole is a perfect light weight application to install on a low power single board computer. After experiencing a few issues with installing Pi-hole (which was likely my fault for not following directions), I tried running Pi-hole as a Docker image. Installing Docker on the Raspberry Pi.
Welcome! We are excited that you want to learn Docker.
This page contains step-by-step instructions on how to get started with Docker. In this tutorial, you’ll learn how to:
- Build and run an image as a container
- Share images using Docker Hub
- Deploy Docker applications using multiple containers with a database
- Running applications using Docker Compose
In addition, you’ll also learn about the best practices for building images, including instructions on how to scan your images for security vulnerabilities.
If you are looking for information on how to containerize an application using your favorite language, see Language-specific getting started guides.
We also recommend the video walkthrough from DockerCon 2020.
Download and install Docker
This tutorial assumes you have a current version of Docker installed on yourmachine. If you do not have Docker installed, choose your preferred operating system below to download Docker:
Install Docker Raspberry Pi Zero
For Docker Desktop installation instructions, see Install Docker Desktop on Mac and Install Docker Desktop on Windows.
Start the tutorial
If you’ve already run the command to get started with the tutorial, congratulations! If not, open a command prompt or bash window, and run the command:
Install Docker Raspberry Pi
Install Docker Raspberry
You’ll notice a few flags being used. Here’s some more info on them:
-d
- run the container in detached mode (in the background)-p 80:80
- map port 80 of the host to port 80 in the containerdocker/getting-started
- the image to use
Tip
You can combine single character flags to shorten the full command.As an example, the command above could be written as:
The Docker Dashboard
Before going too far, we want to highlight the Docker Dashboard, which givesyou a quick view of the containers running on your machine. The Docker Dashboard is available for Mac and Windows. It gives you quick access to container logs, lets you get a shell inside the container, and lets youeasily manage container lifecycle (stop, remove, etc.).
To access the dashboard, follow the instructions for either Mac or Windows. If you open the dashboardnow, you will see this tutorial running! The container name (

below) is arandomly created name. So, you’ll most likely have a different name.What is a container?
Now that you’ve run a container, what is a container? Simply put, a container issimply another process on your machine that has been isolated from all other processeson the host machine. That isolation leverages kernel namespaces and cgroups, features that have been in Linux for a long time. Docker has worked to make these capabilities approachable and easy to use.

Creating containers from scratch
If you’d like to see how containers are built from scratch, Liz Rice from Aqua Securityhas a fantastic talk in which she creates a container from scratch in Go. While she makesa simple container, this talk doesn’t go into networking, using images for the filesystem, and more. But, it gives a fantastic deep dive into how things are working.
What is a container image?
When running a container, it uses an isolated filesystem. This custom filesystem is provided by a container image. Since the image contains the container’s filesystem, it must contain everything needed to run an application - all dependencies, configuration, scripts, binaries, etc. The image also contains other configuration for the container, such as environment variables,a default command to run, and other metadata.

We’ll dive deeper into images later on, covering topics such as layering, best practices, and more.

If you’re familiar with
chroot
, think of a container as an extended version of chroot
. Thefilesystem is simply coming from the image. But, a container adds additional isolation notavailable when simply using chroot.Install Docker Raspberry Pi Os
