]]> PROBLEM

When attempting use Feign to invoke a service through Eureka, the following exception occurs:-

MY-HOST-NAME executing GET http://donkey-kong-service/throw/barrels/10
feign.RetryableException: MY-HOST-NAME executing GET http://donkey-kong-service/throw/barrels/10
	at feign.FeignException.errorExecuting(FeignException.java:84)
	at feign.SynchronousMethodHandler.executeAndDecode(SynchronousMethodHandler.java:113)
	...
Caused by: java.net.UnknownHostException: MY-HOST-NAME
		at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:184)

SOLUTION

Go to the donkey-kong-service app and add the following line to the application.properties:-

eureka.instance.prefer-ip-address=true

Now, when Feign tries to invoke the service, the IP address will be used instead of the OS’ reported hostname.
