How Do I Connect a Service Mesh to Jaeger or Zipkin for Viewing Traces?

Prerequisites

The cluster and namespace where Zipkin is to be installed have been specified.

Procedure

1. Create a Deployment named zipkin.

   Log in to the CCE console and click the cluster name to go to the cluster console. In the navigation pane on the left, choose Workloads. On the Deployments tab, click Create from YAML, and copy the following content to the YAML file:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: zipkin
     namespace: monitoring
   spec:
     progressDeadlineSeconds: 600
     replicas: 1
     revisionHistoryLimit: 10
     selector:
       matchLabels:
         app.kubernetes.io/instance: zipkin
         app.kubernetes.io/name: zipkin
     strategy:
       rollingUpdate:
         maxSurge: 25%
         maxUnavailable: 25%
       type: RollingUpdate
     template:
       metadata:
         labels:
           app.kubernetes.io/instance: zipkin
           app.kubernetes.io/name: zipkin
       spec:
         automountServiceAccountToken: false
         containers:
         - env:
           - name: STORAGE_TYPE
             value: mem
           image: openzipkin/zipkin-slim:latest                                  # Community Zipkin image path. Ensure that you can access this path.
           imagePullPolicy: IfNotPresent
           name: zipkin
           readinessProbe:
             failureThreshold: 3
             httpGet:
               path: /health
               port: 9411
               scheme: HTTP
             initialDelaySeconds: 5
             periodSeconds: 5
             successThreshold: 1
             timeoutSeconds: 1
           resources:
             limits:
               cpu: 500m
               memory: 4Gi
             requests:
               cpu: 100m
               memory: 128Mi
           securityContext:
             readOnlyRootFilesystem: true
             runAsNonRoot: true
             runAsUser: 1000
           terminationMessagePath: /dev/termination-log
           terminationMessagePolicy: File
         terminationGracePeriodSeconds: 30

   The Deployment named zipkin is displayed on the Deployments tab. If the status of zipkin changes to Running, Zipkin has been installed in the monitoring namespace of the target cluster.

   

   

   You can also refer to Zipkin official website documentation to complete the installation.

2. Create a Service of the LoadBalancer type.

   On the cluster console, choose Services & Ingresses in the navigation pane on the left. On the Services tab, click Create Service. Then, configure the parameters as follows:

   • Service Name: Enter a name. zipkin is used as an example here.
   • Service Type: Select LoadBalancer.
   • Selector: Click Reference Workload Label. The label is automatically added.
   • Ports: Configure the container port and Service port. 9411 is used as an example here.

   Retain the default values for other parameters.

   

   The Service named zipkin is displayed on the Services tab.

   

   

   If you do not need to access the Zipkin UI, set Access Type to ClusterIP.

3. Buy a service mesh and interconnect it with Zipkin.

   Log in to the ASM console and click Buy Mesh. In Cluster Configuration, select the cluster in 1. In Observability Configuration, enable tracing. Then, select Third-party Jaeger/Zipkin service for Version, set Service Address and Access Port, and configure other parameters as required.

   

   

   The value of Service Address is {Service name}.{Namespace}.svc.cluster.local. Replace {Service name} and {Namespace} with those specified in 2.

   The value of Access Port is that specified in 2. 9411 is used as an example here.

4. Deploy an experience service () by referring to Grayscale Release Practices of Bookinfo. After the deployment is complete, the services shown in the following figure are displayed on the Service Management page.

   

5. Access the productpage details page to trigger tracing.

   Go to the service mesh details page. In the navigation pane on the left, choose Service Management. On the displayed page, click the external access address http://{IP address}:{Port number}/productpage of the productpage service.

6. View the traces on the Zipkin UI at http://{Public IP address of the load balancer configured for zipkin}:{Access port of zipkin}/zipkin/.
   

   You can obtain the IP address and port for logging in to the Zipkin client as follows:

   • IP address: Go to the console of the cluster where Zipkin is installed. In the navigation pane on the left, choose Services & Ingresses. On the Services tab, view the public IP address of the load balancer configured for zipkin.
   • Port: On the Services tab, view the access port of zipkin.
