Installing Docker CE on Linux

As mentioned earlier, Docker for Desktop is only available for macOS and Windows 10 Pro. If you're using a Linux machine, then you can use the Docker Community Edition (CE), which consists of Docker Engine, plus a few additional tools, such as the Docker Command Line Interface (CLI) and docker-compose.

Please follow the instructions at the following link to install Docker CE for your particular Linux distribution—in this case, Ubuntu: https://docs.docker.com/install/linux/docker-ce/ubuntu/.
