Description

The RayCluster v1 CRD exposes fields that are not currently supported by the ray-cluster Helm chart.

An audit of RayClusterSpec, headGroupSpec, and workerGroupSpecs[] found that the CRD defines 35 fields, while the chart currently renders 19 (with one only partially supported).

Two of the missing fields are not behind any feature gate and work with a stock KubeRay operator today. The Helm chart should expose them consistently with existing options such as headService and autoscalerOptions:

CRD field	Shape
spec.authOptions	mode (disabled | token), enableK8sTokenAuth, secretName
spec.upgradeStrategy	type (Recreate | None)

Deliberately out of scope

These CRD fields are also unexposed, but each is behind an Alpha, default-off feature gate (ray-operator/pkg/features/features.go). Proposal: wait until the gate reaches Beta before adding chart surface for them.

CRD field	Feature gate	Stage
spec.tlsOptions	RayClusterMTLS	Alpha, default false
spec.networkPolicy	RayClusterNetworkPolicy	Alpha, default false
spec.historyServerOptions	RayClusterHistoryServer	Alpha, default false
spec.gcsFaultToleranceOptions.backend / .storage	GCSFaultToleranceEmbeddedStorage	Alpha, default false
