(new feature): get k8s manifests from pipeline

[zelig81]

Intro to the problem

I have kustomization that uses helmChart, so the usual kubectl diff -k will not apply.

My workaround till now was:

kustomize build --enable-helm --load-restrictor LoadRestrictionsNone . | kubectl diff -f -

The only problem here is that for field is immutable I cannot get the real diff.

Proposal

• could you add a possibility to kube-compare to get the manifests from the pipeline argument?
• (optionally - but nice to have) if there is an immutable field to be changed, to show it as recreation as the simplest option

[lack]

The first part of the proposal is probably pretty straightforward; accepting a list of objects on stdin if specifying -f -

Can you expand more on the 2nd part of your proposal? What happens with the tool now? What would you like to see instead?
