Description

In our company, we start to limit the access to platform users on Kubernetes cluster. That means, user will only have permission to operate objects in single namespace. cluster level objects like crds, clusterroles, clusterrolerolebings has to be submited to ops team and ask them to apply to the cluster.

In this case, current deployment way doesn't work in one-click.

kubectl apply -k "github.com/ray-project/kuberay/manifests/cluster-scope-resources"
kubectl apply -k "github.com/ray-project/kuberay/manifests/base"

We need to provide a kustomize override to limit the kuberay to single specificed namespace for a successful deployment.

What is our new expectation on this change?

1. Shall we separate crds, clusterroles, clusterrolerolebings yamls to different places?
2. are we supposed to change this apply procedure to a two phases? 1. apply controllers. 2 apply required crds, clusterroles, clusterrolerolebings yamls
