title: "Exclude namespaces from the Knative webhook"
weight: 70
type: "docs"
---
The Knative webhook examines resources that are created, read, updated, or deleted. This includes system namespaces, which can cause issues during an upgrade if the webhook becomes non-responsive. Cluster administrators may want to disable the Knative webhook on system namespaces to prevent issues during upgrades.
You can configure the label `webhooks.knative.dev/exclude` to allow namespaces to bypass the Knative webhook.
``` yaml
apiVersion: v1
kind: Namespace
metadata:
name: knative-dev
labels:
webhooks.knative.dev/exclude: "true"
```
