Install Jaegar¶

Jaeger is an open source end to end distributed tracing system, allowing users to monitor and troubleshoot transactions in complex distributed systems.

Step 1: Prepare YAML Manifest for Jaegar¶

Copy samples/addons/jaegar.yml manifest from Istio download package.

Step 2: Deploy the Manifest to Install Jaegar¶

Let's apply the modified manifest to install Jaegar:

kubectl apply -f jaegar.yml

Step 3: Access Jaegar Dashboard Locally¶

Let's use kubectl port-forward to access Jaegar dashboard locally:

# Check the port jaegar is exposed at
kubectl get svc -n istio-system | grep tracing

# Forward port 80 of jaegar service on port 20002 of the local host machine
kubectl port-forward svc/tracing 20002:80 -n istio-system

Open any browser on your local host machine and visit localhost:20002. You should see the Jaegar dashboard.

Step 4: Deploy Ingress for Jaegar¶

We'll use an ingress to access Jaegar externally using a load balancer.

jaegar-ingress.yml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: jaegar-ingress
  namespace: istio-system
  annotations:
    # Load Balancer Annotations
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/load-balancer-name: my-load-balancer
    alb.ingress.kubernetes.io/target-type: ip
    # Health Check Annotations
    alb.ingress.kubernetes.io/healthcheck-protocol: HTTP
    alb.ingress.kubernetes.io/healthcheck-port: traffic-port
    alb.ingress.kubernetes.io/healthcheck-path: /
    alb.ingress.kubernetes.io/healthcheck-interval-seconds: '5'
    alb.ingress.kubernetes.io/healthcheck-timeout-seconds: '2'
    alb.ingress.kubernetes.io/success-codes: '200'
    alb.ingress.kubernetes.io/healthy-threshold-count: '2'
    alb.ingress.kubernetes.io/unhealthy-threshold-count: '2'
    # Listerner Ports Annotation
    alb.ingress.kubernetes.io/listen-ports: '[{"HTTP": 80}, {"HTTPS": 443}]'
    # SSL Redicrect Annotation
    alb.ingress.kubernetes.io/ssl-redirect: '443'
    # IngressGroup
    alb.ingress.kubernetes.io/group.name: my-group
spec:
  ingressClassName: alb
  rules:
  - host: jaegar.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: tracing
            port:
              number: 80

Apply the manifest to create ingress for Jaegar:

kubectl apply -f jaegar-ingress.yml

Step 5: Verify Jaegar Installation¶

Visit the Jaegar host (jaegar.example.com) to verify whether you can access the Jaegar Dashboard and view traces.
