Open-feign not working with docker, only on local machine

[ThiagoAnd]

Hi @in28minutes, I manage to get all the services, naming-server, api-gateway, working together on the local machine. But when I try to run with docker I can't connect the two services. The two services show on naming-server(currency-exchange and currency-conversion), I able to call service inside each one(I did a hello word GET, and can call the alone endpoint on currency-exchange).This also is happening with api-gateway

But when I try to call an endpoint that uses open feign it gives me the error(wait for almost 30 minutes):

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

My docker compose:

version: '3.7'

I faced the same problem and I found out that I was setting:
eureka.instance.hostname=localhost
in all the application.properties files.
After I removed this line and rebuilt the image, the problem disappeared.

How you were able to build docker image, because I am not able to create the image and getting build failure as the goal is getting failed.
