+By default kyverno PolicyReports has no priority or severity for policies. So every passed rule validation will be processed as notice, a failed validation is processed as error. To customize this you can configure a mapping from policies to fail priorities. So you can send them as warnings instead of errors. To configure the priorities create a ConfigMap in the `policy-reporter` namespace with the name `policy-reporter-config`. This ConfigMap have to have a property `config.yaml` with the map as YAML content. See the Example for Detailes.

+#### Example
 
 ```yaml
-# values.yaml
+# config.yaml
-# policyPriorities example diff
+policy_priorities:
+  check-label-app: warning
+  require-ns-labels: warning
+```
 
-policyPriorities:
+```bash
-    check-label-app: warning
+kubectl create configmap policy-reporter-config --from-file=config.yaml -n policy-reporter
