@sethiyash Can you make the changes we discussed so that we dont end up generating 2 images with different sha sum for same release.

Just popping to in to say that it's pretty cool that we package kapp-controller with its own kctrl. Also, it serves as a good in-the-wild example for packaging with kctrl. Good things all around! 🎉

Hey @sethiyash ! Now that https://github.com/vmware-tanzu/community-edition/ has been officially retired. It's important that we publish our own package for consumption by Tanzu and the community at large. So happy to help review / get this to a place where we can merge it in soon. (there's no emergency here, just want to make sure you have the support you need)

@sethiyash Do you think we should add a test like installing kapp-controller to ensure that generated package installs successfully before the github action exits?

Challenge here is to install kapp-controller package I need kapp-controller to be installed and after installing kapp-controller if I install it through its Package it will through ownership error as kapp-controller already exists.

Merged this away as we would like a Package with the next release. Next steps would be, having something config-dev which works with kctrl, that would help a lot with local dev for the package if we make changes to the process at some point. A test which reconciles the generated package using kctrl dev while adding a PackageInstall and RBAC on the fly would be awesome!
