Description

Recently, while using RayCluster, a user configured an invalid label in the pod template. I could only discover this issue through the logs of RayOperator. Perhaps, we could use the following methods to help us troubleshoot or avoid such issues more quickly:

• Record relevant failure information using EventRecorder when pod creation fails.
• Add validation logic for the pod template in the validating webhook.
