I’ve seen docker inside a VM before but that was just a dev box for testing

That’s super standard for actual infrastructure

That’s the most reasonable part of the image

Are you not losing loads of performance by stacking vms like that?

Using Docker in a VM on a Hypervisor is industry standard, using docker inside of docker may be okay for CI purposes but I wouldn’t do anything more than that in production if it’s not necessary.

The stack from the image above (Windows>WSL> Docker>Minikube>Docker>App) is something you’d use on a dev machine (not a “real”, production-like test environment), in which case you don’t really care about the performance loss
