Enable service maps using service meshes

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.

Before you begin

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

Role required: discovery_admin.

About this task

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) Informer

Procedure

  • 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).

Note:

If your Prometheus server URL is not the default one, use the following parameter:

--set connectionsDiscovery.prometheusUrl
Modify the k8s_informer.yaml script1. 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 ```
