THANK you. Can you do the same for kubernetes somehow?

A few thoughts/ideas on using this in Kubernetes are discussed in this issue: https://github.com/psviderski/unregistry/issues/4; generally, should be possible with the same idea, but with some tweaking.

Also have a look at https://spegel.dev/, it's basically a daemonset running in your k8s cluster that implements a (mirror) registry using locally cached images and peer-to-peer communication.
