OpenTelemetry with OpenShift Distributed Tracing Platform

Start OpenShift local and create a new project.

$ crc setup
$ crc start
$ eval $(crc oc-env)
$ oc login -u developer
$ oc new-project opentelemetry-js-rhosdt

Install the OpenShift Distributed Tracing Platform Operator

  1. Login as kubeadmin
  2. Go to OperatorHub
  3. Search for Jaeger
  4. Click on Red Hat OpenShift distributed tracing platform and follow the instructions to install.

kubeadmin-login-operatorhub

  1. Login as developer, go to Topology and add the Jaeger Operator to the project.

operator

jaeger

  1. Configure the URL for the JaegerExporter endpoint
❯ oc get svc
NAME                                            TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                                                    AGE
jaeger-all-in-one-inmemory-agent                ClusterIP   None           <none>        5775/UDP,5778/TCP,6831/UDP,6832/UDP                        2m16s
jaeger-all-in-one-inmemory-collector            ClusterIP   10.217.5.57    <none>        9411/TCP,14250/TCP,14267/TCP,14268/TCP,4317/TCP,4318/TCP   2m16s
jaeger-all-in-one-inmemory-collector-headless   ClusterIP   None           <none>        9411/TCP,14250/TCP,14267/TCP,14268/TCP,4317/TCP,4318/TCP   2m16s
jaeger-all-in-one-inmemory-query                ClusterIP   10.217.5.219   <none>        443/TCP,16685/TCP                                          2m16s

We are going to use jaeger-all-in-one-inmemory-collector + our namespace service opentelemetry-js-rhosdt.svc for the JaegerExporter endpoint.

Resulting in the following:

const exporter = new JaegerExporter({
  endpoint: 'http://jaeger-all-in-one-inmemory-collector.opentelemetry-js-rhosdt.svc:14268/api/traces'
});
  1. Deploy the example to OpenShift local
oc apply -f service.cache.yml
cd greeting-service
npm install
npm run openshift:enable:trace
cd ../cute-name-service
npm install
npm run openshift:enable:trace
  1. When you login on Jaeger UI you can see the result like this:
