Tip: When OPA gatekeeper stuck


    We hit issues that all kubectl command stuck like kubectl get pod...etc

    initially, we thought it is a Kubernetes control plane issue but confirmed with the cloud provider, the control plane has some communication issues with the webhook


  It turns out the OPA gatekeeper was stuck and cause webhook issues with the control plane.


1. Delete webhook

kubectl delete validatingwebhookconfigurations.admissionregistration.k8s.io gatekeeper-validating-webhook-configuration

2. It will stabilize the communications with the control plane

3. Delete and redeploy opa keeper deployment
