What is DinD?
For a simple terms, I will use docker to run another docker in docker 🤪
Why is it?
It can be used in many cases, but I use it to simulate a multi-host environment on a single physical machine.
How to do it?
Open your command line and run it
docker run --privileged -d --name <your-docker-name> docker:dind
That's it, now I have a "virtual" of virtual machine to deploy and run the image
Warning ❗❗❗: Because it run with --privileged, so it's only use for dev/test environment => Never use in production
