Docker CLI - This is the CLI that developers usually use to interact with the docker engine.The engine can run on a physical or a virtual machine, but it can only run on top of a Linux kernel i.e. It is responsible for the container lifecycle and isolation of physical resources (compute, memory, storage) that containers can access. It is an open source software that runs on linux as a daemon that makes it possible to run containers on top of Linux kernel.

This is by no means a full conceptual architectural explanation of how Docker works and I would recommend exploring other resources on the web for that purpose. I'll try to break down and explain each term. Experts who know Docker can skip this part.ĭocker can mean a lot of things. This digression explains terminology around Docker. With the disclaimer out of the way, let us deep dive into explaining a little around what is free, what is paid and how exactly can we continue to use 'containers', the core technology, without having to pay for Docker Desktop. has all the rights to monetize their product.
