1.6. Disabling the default network policies

Prerequisites

• You have one of the following permissions to access the cluster:

  • Cluster administrator permissions on OpenShift Container Platform
  • Cluster administrator permissions on Red Hat OpenShift Service on AWS
  • Dedicated administrator permissions on OpenShift Dedicated
• You have installed the OpenShift CLI (oc).
• You have access to a project with the appropriate roles and permissions to create applications and other workloads.
• You have installed the OpenShift Serverless Operator, Knative Serving, and Knative Eventing on your cluster.
• You have installed Red Hat OpenShift Service Mesh with the mTLS functionality enabled.

Procedure

• Add the serverless.openshift.io/disable-istio-net-policies-generation: "true" annotation to your Knative custom resources.

  참고

  The OpenShift Serverless Operator generates the required network policies by default. When you configure ServiceMeshControlPlane with manageNetworkPolicy: false, you must disable the default network policy generation to ensure proper event delivery. To disable the default network policy generation, you can add the serverless.openshift.io/disable-istio-net-policies-generation annotation in the KnativeEventing and KnativeServing custom resources (CRs).

  1. Annotate the KnativeEventing CR by running the following command:

     $ oc edit KnativeEventing -n knative-eventing

     Example KnativeEventing CR

     apiVersion: operator.knative.dev/v1beta1
     kind: KnativeEventing
     metadata:
       name: knative-eventing
       namespace: knative-eventing
       annotations:
         serverless.openshift.io/disable-istio-net-policies-generation: "true"

  2. Annotate the KnativeServing CR by running the following command:

     $ oc edit KnativeServing -n knative-serving

     Example KnativeServing CR

     apiVersion: operator.knative.dev/v1beta1
     kind: KnativeServing
     metadata:
       name: knative-serving
       namespace: knative-serving
       annotations:
         serverless.openshift.io/disable-istio-net-policies-generation: "true"
