To many of us, Docker's internals are a mystery. chroot/pivot_root, kernel namespaces, cgroups - what exactly are they used for?
Based on the [Build your own X](https://github.com/danistefanovic/build-your-own-x) tutorial format, I'm building a [Build your own Docker](https://codecrafters.io/challenges/docker) challenge. It isn't quite ready yet, but [early access trials](https://codecrafters.io/early-access) will start very soon.
Any feedback on the structure of the course would be highly appreciated!

On my read list.
Now do a Kube one!
Signed up. Sounds great.
This sounds really cool. Will you post here again when it’s out of early access?

Signed up, looks awesome!
If you would use containerd it might be super easy but if you are writing it “no deps” it might be interesting.
