Docker is officially supported both on Raspberry Pi 3 and 4. Installing Docker is just a matter of single-liner command. All you need to do is a simple curl command:
curl -sSL https://get.docker.com/ | sh
to get Docker binaries installed flawlessly. Isn’t it damn simple?
Raspbian is a free operating system based on Debian optimized for the Raspberry Pi hardware. An operating system is the set of basic programs and utilities that make your Raspberry Pi run. However, Raspbian provides more than a pure OS: it comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation on your Raspberry Pi.
Docker today support the latest Raspbian Buster release. If you really want to play around with stable release of Docker for Raspbian Buster, then head over to this link.
Under this blog post, I will showcase how to install latest Docker Engine 19.03.1 on Raspbian OS Buster release flawlessly.

Prerequisite
- Flash Raspbian OS on SD card
If you are in Mac, you might need to install Etcher tool. If on Windows, install SDFormatter to format SD card as well as Win32installer to flash Raspbian ISO image onto the SD card. You will need SD card reader to achieve this.
Booting up Raspbian OS
Just use the same charger which you use for your mobile to power on Raspberry Pi box. Connect HDMI port to your TV or display. Let it boot up.
The default username is pi and password is raspberry.
Enable SSH to perform remote login
To login via your laptop, you need to allow SSH service running. You can verify IP address command via ifconfig command.
