Docker Engine Installation

First of all, you need to have a docker engine installed on your machine. For education and demos it is possible to use docker, while if you are using it for a commercial solution (for example working on a project), you will have to have a proper license.

📖 Commercial use of Docker Desktop in larger enterprises (more than 250 employees OR more than $10 million USD in annual revenue) now requires a paid subscription. The grace period for those that will require a paid subscription ends on January 31, 2022.

Some alternatives inlcude for example podman (which I am currently using). For the purposes of this activity, the two experiences are identical.

Installing Docker

get docker at the following link according to your operating system.

https://docs.docker.com/get-docker/

Installing podman

You can find detailed installation instructions here for different operating systems.

On macOS (tested on Monterey 12.2.1) I issued the following commands after facing some problems, it seemed that the game changer was to add a specific name to the podman machine.

brew install podman

initialize virtual machine (this will download a base image, might require some time and some bandwidth)

podman machine init myvm

to start the virtual machine running podman, use the following command

podman machine start myvm

For future reference - uninstall

If you need to remove in the future podman from your mac, perform the following commands

brew uninstall podman

rm -fr ~/.config/containers/
rm -fr ~/.local/share/containers/
