[Bug]: Operator showing error with injection sidecar #2105

Open minh-oolio opened 1 year ago

minh-oolio commented 1 year ago

What happened?

hello team, I implemented sidecar injected on deployment as this document https://github.com/jaegertracing/jaeger-operator/blob/main/examples/business-application-injected-sidecar.yaml and found error message from jaeger operator 

1.6672863326932034e+09  INFO    annotation present on deployment    {"namespace": "applicationA", "deployment": "accounts"}
1.6672863326933312e+09  INFO    no suitable Jaeger instances found to inject a sidecar  {"namespace": "applicationA"}

Steps to reproduce

  1. deployed jaeger and jaeger operator by helm chart with latest version (namespace jaeger)
  2. implement sidecar inject on deployment of application (other namespace applicationA )
  3. we are using traefik as service mesh https://traefik.io/blog/application-request-tracing-with-traefik-and-jaeger-on-kubernetes/
  4. check log operator and found error message no suitable Jaeger instances found to inject a sidecar

here is services of jaeger was deployed image

Expected behavior

Able to tracing appliacation api. something like this picture image

Relevant log output

Operator pod logs

1.6672916883622577e+09  INFO    no suitable Jaeger instances found to inject a sidecar  {"namespace": "applicationA"}

Seems your deployment needs an injection. But can not find a Jaeger instance in the same namespace. In that case your sidecar doesnt know where it should send the collected data.

Have a look here:

hi @frzifus thanks for your response Is there any solution for my case? I deployed jaeger and jaeger operatorin jaeger namespace and tracing application on other namespace. thank you very much

frzifus commented 1 year ago

Hi @minh-oolio, from my understanding you need to define WATCH_NAMESPACES in your operator.yaml file. To make sure the right jaeger instance is picked, change your annotation value to your instance name.

kind: Deployment
metadata:
  name: myapp
  annotations:
    "sidecar.jaegertracing.io/inject": "<INSTANCE_NAME>"

On the operator side, your jaeger instance should then be found here.

hi @frzifus thanks a lot for your suggestion it seem it able to inject sidecar to pod but it still trace on the console i am concern, do i need to change jaeger-operator-jaeger to jaeger-operator-jaeger.jaeger.svc please advise on it

k get jaegers
NAME                     STATUS    VERSION   STRATEGY   STORAGE   AGE
jaeger-operator-jaeger   Running   1.38.0    allinone   memory    3h39m

with this annotaion 

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gateway
  annotations:
    sidecar.jaegertracing.io/inject: jaeger-operator-jaeger

and here is a log of jageragent injected to gateway pod
