After completing this task, you understand how to have your application participate in tracing with Jaeger, regardless of the language, framework, or platform you use to build your application.

This task uses the Bookinfo sample as the example application.

To learn how Istio handles tracing, visit this task's overview.

Before you begin

  1. To set up Istio, follow the instructions in the Installation guide and then configure:

    a) a demo/test environment by setting the --set tracing.enabled=true Helm install option to enable tracing “out of the box”

    b) a production environment by referencing an existing Jaeger instance, e.g. created with the operator, and then setting the --set global.tracer.zipkin.address=<jaeger-collector-service>.<jaeger-collector-namespace>:9411 Helm install option.

  2. Deploy the Bookinfo sample application.

Accessing the dashboard

Remotely Accessing Telemetry Addons details how to configure access to the Istio addons through a gateway. Alternatively, to use a Kubernetes ingress, specify the Helm chart option --set tracing.ingress.enabled=true during install.

For testing (and temporary access), you may also use port-forwarding. Use the following, assuming you've deployed Jaeger to the istio-system namespace:

$ kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=jaeger -o jsonpath='{.items[0].metadata.name}') 15032:16686

Open your browser to http://localhost:15032.

Generating traces using the Bookinfo sample

  1. When the Bookinfo application is up and running, access http://$GATEWAY_URL/productpage one or more times to generate trace information.

  2. From the left-hand pane of the dashboard, select productpage.default from the Service drop-down list and click Find Traces:

    Tracing Dashboard
    Tracing Dashboard
  3. Click on the most recent trace at the top to see the details corresponding to the latest request to the /productpage:

    Detailed Trace View
    Detailed Trace View
  4. The trace is comprised of a set of spans, where each span corresponds to a Bookinfo service, invoked during the execution of a /productpage request, or internal Istio component, for example: istio-ingressgateway.


  1. Remove any kubectl port-forward processes that may still be running:

    $ killall kubectl
  2. If you are not planning to explore any follow-on tasks, refer to the Bookinfo cleanup instructions to shutdown the application.
