Current list of api-resources. Might be different in openshift. Need to look a scheme.go and update according to that.

Update can be isolated to kuberenetes.go

Naman1997 commented 2 years ago

Might be useful to look at go generics for the for loop and concurrency patterns for calling all these in a concurrent manner. The file system should not be affected as each type of object will be present in a separate folder.

Naman1997 commented 2 years ago

Skipping usage of generics as client-go does not seem to support it right now. https://github.com/kubernetes/kubernetes/issues/106846

Saving the most common types for now
