Subject: Setting the scope for mutating webhooks rules Problem: The linkerd-proxy-injector-webhook-config, linkerd-jaeger-injector-webhook-config, and linkerd-tap-injector-webhook-config mutating webhooks raise a warning on GKE that says "Update webhook to no longer intercept system requests." in the GCP console recommendation section. This is because the scope is set to *. This also happens if scope is Namespaced, and kube-system and kube-node-lease namespaces are not excluded using namespaceSelector. Solution: Setting the scope to Namespaced for both webhooks, and the user can set the namespaceSelector in the helm values. Validation: This should not change the webhooks behaviour as all webhooks are triggered only by pod/service creation requests, and pods/services are namespaced resources.
