    • Enable application service maps based on the traffic between the workloads in Kubernetes by using Istio or Linkerd or service meshes as part of Kubernetes Visibility Agent (KVA) installation.

    Vorbereitungen

    You must have a Prometheus server and provide the Prometheus URL.

    Role required: discovery_admin.

    Warum und wann dieser Vorgang ausgeführt wird

    If you use a service mesh, a pod running on every node (Informer) communicates with a Prometheus server to get the traffic information. For more information, see Install Kubernetes Visibility Agent (KVA)

    Prozedur

    Set parameters either during Helm chart archive installation or by modifying the Kubernetes YAML file provided by ServiceNow.
    MethodActions
    During Helm installation
    In the Helm install command, add the following parameter:
    --set connectionsDiscovery.method=<METHOD>
    where <METHOD> is the URL for either Istio (http://prometheus.istio-system:9090) or Linkerd (http://prometheus.linkerd-viz:9090).
    Hinweis:
    If your Prometheus server URL is not the default one, use the following parameter:
    --set connectionsDiscovery.prometheusUrl
    Modify the k8s_informer.yaml script
    1. Access the k8s_informer.yaml script.
    2. Set the environment variable k8s_informer.yaml by entering either Istio or Linkerd in quotation marks: 
      -- name: GET_CONNECTIONS_METHOD value: ""
    3. Run the following command:
      kubectl apply -f k8s_informer.yaml
