Install and Configure Docker on Linux

This blueprint is for the installation and configuration of Docker Engine and Docker Compose.

This has been tested on Raspberry Pi 4 with Ubuntu Server 20.04.2 LTS 64-bit.

Docker Engine

Docker Engine is an open source containerization technology for building and containerizing your applications. This blueprint installs the Docker Engine.

Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. This blueprint installs Docker Compose.
