Hello all,
I created two spring boot services named servicea and serviceb, and I am calling the serviceb endpoint in servicea through feign client. if I deploy locally it is working fine as expected. but when I am deploying the same services in Kubernetes it is throwing 404 not found.
Error: service A failed with exception: status 404 reading ServiceBClient

Hi Sunil,
how are you calling the service endpoints?
If your apps work locally then (as an example) you should be able to make a request to “serviceb” pod by doing something like this:
curl http://serviceb:8086/
If serviceb and servicea are in the same namespace.
Is that what you are doing?
Hi,
I am using feignclient for communication
What do the urls that you are using in feignclient look like?
Can you share a snippet of how you want servicea to talk to serviceb?
