Deploy a Node.js Application in the Kyma Runtime

[bstempien]

Tutorials: https://developers.sap.com/tutorials/deploy-nodejs-application-kyma.html

The "k8s-deployment-backend.yaml" Network Policy contains an error that will prevent access to the application and thus the Tutorial will Fail. The ingress policy namespaceSelector should be changed to:

ingress:
    - from:
        - podSelector:
            matchLabels:
              app: istio-ingressgateway
          namespaceSelector:
            matchLabels:
              kubernetes.io/metadata.name: istio-system

By default the istio-system Namespace does not have a label called name. But as of Kubernetes v1.21 there is a immutable label "kubernetes.io/metadata.name" added to every namespace. Thus the update to the Network Policy will allow the Tutorial to work out of the box.
