@harryge00 Thanks for the contribution. I fully understand the background and scope of this PR. Let's add some description in the PR for other reviewer?

[Jeffwan]

1. We also need a script to generate the clientset. Can you please add it as well?
2. Just like to confirm we have to restructure api folder. Is that correct? Support clientset for RayCluster objects  #29 (comment)

@harryge00 Can you help address the comments?

[Jeffwan]

I am thinking maybe we can split PRs into smaller ones?

• ​Reorganize PR and update reference in controllers and tools.
• ​Add codegen scripts and api changes (doc.go, spec.go etc)
• ​Generate clients, listers, informers.

What do you think? @harryge00 @chenk008

@Jeffwan
Sorry for the late reply. I am still struggling with kubebuilder actually... I agree with you, we can split it into smaller ones. For scripts to generating clientset, you mean like https://github.com/knative/pkg/blob/main/hack/update-codegen.sh ?

[harryge00]

If this PR blocks u, u can take it and make a small one first. 😭
I can take other ones

[Jeffwan]

@harryge00 no worries, Could I know what's the problem of kubebuilder? Anything I can help here?

[Jeffwan]

@harryge00 Can you reach out to me on Ray or Kubernetes Slack channel? I can help you figure this out.
