@gtsiolis Do you have a reference for what you mentioned here? 🤔

[gtsiolis]

@geropl For this iteration, we could reuse the text-based pattern we already have in project-level environment variables, see example settings. I'll open a follow-up issue with some more minor UX issues.

/werft run with-preview=true

@geropl I quickly summarized some UX issues in #11463, including the point you added here about warning users.

[geropl]

Awesome @gtsiolis ! I tried to keep the checkboyes in #11463 up to date.

This is what we have now:

Not satisfied with the colors of the warning, but I'd rather have it there then not. 🧘 I tried to fix everything that does not require taste design experience. I feel next round has to be tackled by someone else. 😉

LGTM on the installer side, but How about also removing the BlockedRepository type both from

• install/installer/pkg/config/v1/experimental/experimental.go
• install/pkg/components/server/types.go

as its not used anymore.

/hold for the same

[geropl]
