userservice는 회원가입 조회 전부 정상으로 되는 것 확인하였습니다. 그런데 orderservice를 기동하니 userservice가 아래와 같은 로그를 보이고 죽어버리는데 어느부분을 체크해봐야 할까요.?

안녕하세요, 이도원입니다. 

올려주신 로그의 에러 메시지는 UnknownHostException으로 user-service에서 order-service로 주문 내역을 조회 할 때, feign-client를 사용하는데, 여기에서 order-service를 찾지 못하는 오류가 발생한 것 같습니다. eureka에 order-service가 정상작동 되었는지 확인해 보시고, 이상이 없다면, docker로 기동하기 전에 user-service와 order-service가 잘 연동되었는지도 확인해 보시기 바랍니다. 이 모든 것에 이상이 없다면, docker-compose로 기동했을 때, order-service와 user-service, service-discovery 등 모든 서비스들이 같은 network에서 기동되었는지 확인해 보시기 바랍니다. 

감사합니다.
