09/24/2025, 4:00 PMHi everyone, I'd like to implement a mutating admission policy. The Rancher docs seem to push Kubewarden, but 1) I can't find much info about it compared to Kyverno which is much more popular, and 2) The docs seem to imply that its readily available as a Rancher app, but it does not seem to be part of the catalogue.
I would appreciate some guidance. Thanks!

I have a gut feeling the UI Extension has been made available only to Rancher Prime users (i.e. enterprise). That seems to be the way the Rancher docs present it, but they don't say it outright so I'm not sure.

So I dont't have the pretty UI.

09/25/2025, 12:11 PM@careful-piano-35019 As I have mentioned I was able to install kubewarden, the question is moreso about what the Rancher docs claim and the UI extension in general.
