• added k3d field to index.yaml
  • if false the application can't be installed on a k3d cluster.

Sorry @tomekz, I was out last week, and the team was focussing on the v2.3 release for this week, so they missed your PR.

I'll review it today.

Thanks @fharper
I've signed off all the commits also as I see it is required
I did open one side quest tiny PR for console, not related to the issue. Pls have a look

@tomekz can you sign your commit please? In the meantime, I'll review the PRs for this.

I read somewhere you did, but maybe you didn't push your change as they are not signed. If you're successful, you'll see the verified badge next to them, like this.
