Hi Prakhar, the webhook is an optional component in the Flink Operator. It's responsible mainly for validation through: https://github.com/apache/flink-kubernetes-operator/blob/main/flink-kubernetes-operator/src/main/java/org/apache/flink/kubernetes/operator/validation/DefaultValidator.java
This is also enforced in the operator, without the webhook anyway. There's a convenient functionality implemented in a mutating webhook component that adds labels to session jobs to support label based filtering: https://github.com/apache/flink-kubernetes-operator/blob/main/flink-kubernetes-webhook/src/main/java/org/apache/flink/kubernetes/operator/admission/mutator/FlinkMutator.java We're adding documentation for the webhook soon.
