request: Add Reusable Kind cluster creation CI action

[jaiakash]

Why we need it?

We have lot of protect which uses CI action which creates kind cluster for its CI. I want to add a reusable composite action (.github/actions/create-cluster) that spins up a local Kubernetes cluster (Kind) so CI jobs can run against a real cluster instead of each workflow re-implementing the setup inline.

The same action already exists and is in use in the

• sdk https://github.com/kubeflow/sdk/blob/main/.github/workflows/test-e2e.yaml
• trainer https://github.com/kubeflow/trainer/blob/master/.github/workflows/test-e2e.yaml
• And planning to add in mcp-server as part of this feat(ci): add Kubernetes E2E tests against live cluster mcp-server#109

Requirement

• Adds common action for cluster creation with inputs for Kubernetes version and the Kind node image.
• Exports KUBECONFIG so subsequent steps can talk to the cluster directly.

@jaiakash this is not a PR, please update the issue title & description to reflect this 😅

Also it would make sense to change the requirement from installing trainer to install a list of kubeflow subprojects (which initially might only support trainer) 🤔

Hi @christian-heusel yeah, I think the reframed language better conveys what I’m trying to request.

Also it would make sense to change the requirement from installing trainer to install a list of kubeflow subprojects

I agree with this. However, I’d prefer to keep the responsibilities separated: one action for creating the cluster, and a separate action for installing the required Kubeflow tools/subprojects.

Would love to know other's opinion!

Wdyt about #1068 (comment)?

Based on that, we can decide the scope of this action?

@jaiakash @christian-heusel Hi, I'd love to take this on as my next contribution (I just submitted the PR for the reusable boilerplate action).
Before I get started, I want to make sure I build exactly what is needed. Based on the discussion above what is the final decision on the scope?

Should this action strictly just create the Kind cluster and export the Kubeconfig, or should it also include the logic to install the required Kubeflow tools/subprojects?

Let me know the final verdict and I'll start working on it right away! /assign
