Linkerd destination repeatedly logging endpoint profile translator errors
What is the issue?
We have prometheus deployed and the destination controller is spamming these logs:
{"addr":":8086", "component":"endpoint-profile-translator", "context-ns":"prometheus", "context-pod":"prometheus-prometheus-0", "kubernetes":{…}, "msg":"failed to find LINKERD2_PROXY_INBOUND_LISTEN_ADDR environment variable in any container for given pod spec", "remote":{…}, "time":"2024-06-12T17:59:54Z"}
It only applies to the prometheus namespace and there are no other namespaces reporting this log.
How can it be reproduced?
Deploy prometheus operator and mesh it with Linkerd.
Logs, error output, etc

Hi @bc185174 – how exactly are you deploying and meshing Prometheus? There are a few too many ways of doing that to just run with "deploy and mesh Prometheus"...

Apologies - we are deploying it via the prometheus operator https://github.com/prometheus-operator/prometheus-operator. Then deploy linkerd 2.14.10 and auto mesh the prometheus pods.
OK, I think the immediate questions here are:
- How often do the logs show up?
- What pod is Prometheus trying to talk to? can we get the YAML for that Pod?
Thanks!
Closing this one; please reopen if you're still having this issue and can provide more details.
