I have a kubernetes cluster on google cloud platform, and on it, I have a jaeger deployment via development setup of jaeger-kubernetes templates because my purpose is setup elasticsearch like backend storage, due to this, I follow the jaeger-kubernetes github documentation with the following actions

Here are configured the URLs to access to elasticsearch server and username and password and ports

kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-kubernetes/master/production-elasticsearch/configmap.yml

And here, there are configured the download of docker images of the elasticsearch service and their volume mounts.

kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-kubernetes/master/production-elasticsearch/elasticsearch.yml

And then, at this moment we have a elasticsearch service running over 9200 and 9300 ports

 kubectl get service elasticsearch                                                                                                                                [a89fbe2]
NAME            TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)             AGE
elasticsearch   ClusterIP   None         <none>        9200/TCP,9300/TCP   1h
  • I've follow with the creation of jaeger components using the kubernetes-jaeger production templates of this way:

λ bgarcial [~] → kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-kubernetes/master/jaeger-production-template.yml        
deployment.extensions/jaeger-collector created
service/jaeger-collector created
service/zipkin created
deployment.extensions/jaeger-query created
service/jaeger-query created
daemonset.extensions/jaeger-agent created

λ bgarcial [~/workspace/jaeger-elastic] at  master ?

According to the Jaeger architecture, the jaeger-collector and jaeger-query services require access to backend storage.

And so, these are my services running on my kubernetes cluster:

λ bgarcial [~/workspace/jaeger-elastic] at  master ?
→ kubectl get services                                                                                  [baefdf9]
NAME               TYPE           CLUSTER-IP      EXTERNAL-IP      PORT(S)                        AGE
elasticsearch      ClusterIP      None            <none>           9200/TCP,9300/TCP              3h
jaeger-collector   ClusterIP   <none>           14267/TCP,14268/TCP,9411/TCP   3h
jaeger-query       LoadBalancer   80:30398/TCP                   3h
kubernetes         ClusterIP     <none>           443/TCP                        3h
zipkin             ClusterIP    <none>           9411/TCP                       3h

λ bgarcial [~/workspace/jaeger-elastic] at  master ?
  • I going to configmap.yml elastic search file kubectl edit configmap jaeger-configuration command in order to try to edit it in relation to the elasticsearch URLs endpoints (may be? ... At this moment I am supossing that this is the next step ...)

I execute it:

λ bgarcial [~] → kubectl edit configmap jaeger-configuration 

And I get the following edit entry:

 apiVersion: v1
  agent: |
      host-port: "jaeger-collector:14267"
  collector: |
      server-urls: http://elasticsearch:9200
      username: elastic
      password: changeme
        http-port: 9411
  query: |
      server-urls: http://elasticsearch:9200
      username: elastic
      password: changeme
  span-storage-type: elasticsearch
kind: ConfigMap
  creationTimestamp: "2018-12-27T13:24:11Z"
    app: jaeger
    jaeger-infra: configuration
  name: jaeger-configuration
  namespace: default
  resourceVersion: "1387"
  selfLink: /api/v1/namespaces/default/configmaps/jaeger-configuration
  uid: b28eb5f4-09da-11e9-9f1e-42010aa60002

Here ... do I need setup our own URLs to collector and query services, which will be connect wiht elasticsearch backend service?

How to can I setup the elasticsearch IP address or URLs here?

In the jaeger components, the query and collector need access to storage, but I don't know what is the elastic endpoint ...

Is this server-urls: http://elasticsearch:9200 a correct endpoint?

I am starting in the kubernetes and DevOps world, and I appreciate if someone can help me in the concepts and point me in the right address in order to setup jaeger and elasticsearch as a backend storage.

When resolving a service in Kubernetes,

Assume a Service named foo in the Kubernetes namespace bar. A Pod running in namespace bar can look up this service by simply doing a DNS query for foo. A Pod running in namespace quux can look up this service by doing a DNS query for foo.bar.

Since Jaeger is in the same namespace, then yes, it can resolve the Elasticsearch endpoint with just elasticsearch. Your configuration is correct in that respect and requires no changes.

If Jaeger were located in another namespace, you could specify the full DNS record elasticsearch.default.svc.cluster.local.
