There was a problem hiding this comment.
Hey! I just read through it, the first section reads nicely! I'm just a bit confused about the air-gapped part, maybe we can have a call about it.
One thing in general, adress the reader as "you" and don't use the "we". Also further down, don't say "the customer". The docs are written for the customer, so it's just "you"

Fixes stackabletech/issues#437
I switched out Kyverno for the Sigstore Policy Controller, since the support for air-gapped environments is more mature than Kyverno's (at the moment at least) and added some guidelines and explanations on how signature verification in an air-gapped environment can be done.
Notes for the reviewer:
The whole topic is not trivial and maybe not easy to reproduce, this documentation might be helpful as well: https://github.com/stackabletech/documentation-airgapped-setup
It's a step-by-step guide on how to setup an air-gapped cluster on IONOS and how to configure the Policy Controller with a TUF mirror.
