Issue with installation

Hello,

I’m not sure this is a bug or something I’m doing wrong. I’m having some issues installing tracetest and getting it to work. I’d appreciate it if you could point me in the right direction.

Describe the bug I tried installing using the setup script. Installation seems to be successful(no error log seen)

Log I tried the port forwarding as instructed after the installation but I get this error:

○ → kubectl port-forward --namespace my-test-namespace svc/tracetest 8080:8080
Forwarding from 127.0.0.1:8080 -> 8080

Upon inspecting tracetest pod log, it’s in CrashLoopBackOff state:

○ → k get pods --namespace my-test-namespace
NAME                         READY   STATUS             RESTARTS       AGE
jaeger-748ccdcff7-xwkbm      1/1     Running            0              36m
tracetest-5648f7bff7-lwjnz   0/1     CrashLoopBackOff   12 (74s ago)   37m
tracetest-postgresql-0       1/1     Running            0              37m

So the tracetest pod is having trouble here, looking at the pod log, I see.

○ → kubectl logs --namespace my-test-namespace -f svc/tracetest
2022/08/11 16:52:44 could not get trace provider: could not create exporter: could not create gRPC connection to collector: context deadline exceeded

otel collector pod seemed ok:

○ → k get pods
NAME                              READY   STATUS    RESTARTS   AGE
otel-collector-5d475cfc6b-snznq   1/1     Running   0          61m

But the log says it’s not:

○ → k logs otel-collector-5d475cfc6b-snznq

I’ve got it working, thank you very much for your help. I was hoping to see more calling relationships in the Graph view but I’m only seeing 1 service so I will investigate a bit further.

In the meantime, I think it’d be super powerful to have some e2e framework integrated, such as Cypress(which Testkube has), and have trace id collected during the UI interaction. Maybe some time in the future 🙂

@ljo-jones Glad to see you got Tracetest installed successfully. Ping me (KenHamric) over on Discord - would like to hear how you are using Tracetest & get more thoughts from you on how you would like to see it integrated with Cypress. Also wanted to send you some swag!!
