there are no steps there on how to re-produce the problem. what are the exact steps for that?

wind57 commented 5 months ago

@ryanjbaxter would you be so kind for add the feedback tag in here? thank you

rsrini7 commented 5 months ago

Apologies, The code i used inside my office kubernetes setup. I am tring to setup in my local minikube to reproduce the same. May i know, what are the scenarios the exception can occur so that i can add ingress / egress rules if anything to be required to be added ?

wind57 commented 5 months ago

From what I have looked, you are reporting the issue against an existing repo. So it seems you are using that repository and you are getting the issue, no?

If so, just tell us how you run that repository locally. Otherwise, that error comes from a client we are using, not directly from our code, so I can't tell anything about scenarios :(

rsrini7 commented 5 months ago

Yes, i am using that given repo in my office kubernetes environment and i am getting the same exception when i deploy into k8s and when the application starts the above mentioned exception occurs.

when i run with locally there is no issues and application starts. Its because discoveryclient is causing the exception when i deploy the application to k8s. if i remove discovery client tha app starts and but client registrations happens but the client status all are down.

wind57 commented 5 months ago

well, without a way for us to reproduce that in minikube/kind for example, with clear instructions on what we must do, it is complicated to tell what is going on...

rsrini7 commented 5 months ago

Agree. will try to reproduce in minikube and get back.
