Personally, I like to use Docker containers on my Raspberry Pis as they come with a great layer of abstraction and portability. Here is how to get your Raspberry Pi ready for Docker and Docker-Compose.

Raspberry Pi 400
1. Setup your Raspberry Pi with Raspbian, Wifi and SSH access
Jun 24, 2020 As for which image to choose, Docker works on all variants and editions of Raspberry Pi OS. 32-bit vs 64-bit. The 32-bit edition of Raspberry Pi OS will run on every board, including Raspberry 2. If you have a Raspberry Pi 3 or 4, you have the opportunity to pick the 64-bit variant too. Using a 64-bit operating system will give you better. Using Docker on Raspberry Pi 4. In this section, we will show you how to use Docker on your Raspberry Pi 4. If you have never used Docker, this section should help you get started. To run a Docker container, you need a Docker image on which the Docker container will be based. A Raspberry Pi cluster can be used anytime you want to improve performance or availability, and there are many use cases including serving web content, mining cryptocurrency, processing large amounts of data (using tools like hadoop), and much more. This guide will show you how to run a Raspberry Pi cluster using Docker Swarm.

If your Raspberry Pi is already set up, you can skip this step and continue to step 2.
The most straight forward way to install Raspbian on your Raspberry Pi is through the official Raspberry Pi Imager. It comes with all the tools needed to prepare and flash an SD card with the Raspbian version you want to install. For this tutorial, I am assuming, that you are using the smallest Raspbian 'Lite' version.
To ensure, that SSH is enabled on the first start of your Raspberry Pi, we need to add an additional empty file called ssh to the SD card's root directory after is has been flashed with the image.
This is especially useful, if you are running your Raspberry Pi in headless mode with no screen or keyboard attached.
If you want to connect the Raspberry Pi to a Wifi network, it might be useful to also provide the network details for the first startup. For this, define a wpa_supplicant.conf file in the same root folder with the following content. Make sure, it uses the line feed (LF) newline character.
If you are unsure about your 2 letter ISO 3166-1 country codes, you can look it up here.
After booting up your device, you can connect to it via SSH by using its IP address, that you will likely get from your router's web interface.
The default username is pi and the standard password is raspberry.
It's highly recommended to change the password on the first connection. You can do this and configure many other useful things in the handy Raspberry Pi Config tool.
2. Install Docker

The connection is set up, it's time to install Docker. Mac app store mojave. Fortunately, Docker provides a handy install script for that.
After the script has finished, add the permissions to the current user to run Docker commands.
Reboot the Raspberry Pi to let the changes take effect.
3. Install Docker-Compose
Docker-Compose usually gets installed using pip3. For that, we need to have python3 and pip3 installed. If you don't have it installed, you can run the following commands.
Once python3 and pip3 are installed, we can install Docker-Compose using the following command.

4. Enable the Docker system service to start your containers on boot
This is a very nice and important addition. With the following command you can configure your Raspberry Pi to automatically run the Docker system service, whenever it boots up.
With this in place, containers with a restart policy set to always or unless-stopped will be re-started automatically after a reboot.
5. A sample Docker Compose file
This section shows a quick sample of a Docker-Compose file, which starts three containers that once started will automatically come up, if the Raspberry Pi get fully power cycled. To learn more about the sample project I used here, visit my Docker Speed Test project on GitHub.
To start the containers using Docker-Compose, run the following command.
