@KnVerey I read in the docs that both the Go and the Exec plugins are slated for deprecation .. May I undertsand a rough timeline / target release for the removal of those from Kustomize? ..

[KnVerey]

We do know that we will remove them eventually, but there's no specific target yet. It will depend in part on when we're able to fully activate the replacements in kubectl kustomize (which only releases 3x/year), as we'll need an overlap release before removal. (Re "Exec" deprecation: In case it isn't clear, the KRM Functions version of Exec extensions is being preserved/graduated.)

Hey there! I'm learning how Kustomize works (and also plugins). I still don't understand what KRM-driven feature means; however, I'm actively reading and I included some notes about my study and todos for later. These are personal todos that I'm planning to come back to but I think they might help others.

Jargon note: For an explanation about the Kubernetes Resource Model (KRM) term, see the following links.

1. https://github.com/kubernetes/design-proposals-archive/blob/main/architecture/resource-management.md
2. https://twitter.com/bgrant0607/status/1406998402768859137?lang=en
3. https://github.com/kubernetes-sigs/kustomize/blob/master/cmd/config/docs/api-conventions/functions-spec.md
4. https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/2953-kustomize-plugin-graduation#key-terminology

And also see the example in the Kubernetes Resource Model (KRM) Functions Specification Examples section. I can't parse the example yet; however, it seems to allude to containers that take input and print output so I'm guessing the example might work in a Unix pipeline like the following command illustrates.

$ echo hello | docker run --interactive debian bash -c 'cat; echo world'
hello
world

Done: After I figure out what that example in the Kubernetes Resource Model (KRM) Functions Specification Examples section means, then add another example where you actually run a kubectl, kustomize, or docker command. Edit: For an excellent guided Containerized KRM Functions example, see https://kubectl.docs.kubernetes.io/guides/extending_kustomize/containerized_krm_functions/#guided-example. For a presentation about KRM Functions, see https://youtu.be/YlFUv4F5PYc?t=997. For a live working session about KRM Functions, see https://youtu.be/iHhCssvnv6Y?t=1155. Edit: To learn about Kustomize plugins by example, see Kustomize plugins public gist.

Is there any way to formalize what "Alpha" status means here? It's been 2+ years...

@KnVerey Thoughts on finalizing the current state as "v1" and letting a nebulous "v2" linger instead of keeping Alpha status forever?
