도커로 실행된 config-service 의 `rabbitmq:5672` bind Exception

Question

안녕하세요 강사님. 제가 놓친것이 있는지 아래에 보시는바와 같이 rabbitmq:5672 에 연결을 못하는것 같습니다 재차 틀린부분을 검토했으나, 알수가 없네요.. 아래는 `config-service` 로그 내용입니다 . ____ _ __ _ _ /\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ / _` | \ \ \ \ \/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.4.6) 2021-06-19 02:07:59.458 INFO 1 --- [ main] c.e.c.ConfigServiceApplication : The following profiles are active: default 2021-06-19 02:08:00.698 INFO 1 --- [ main] o.s.cloud.context.scope.GenericScope : BeanFactory id=bc9f3347-c72c-3e7c-b9c9-e642fc88c55a 2021-06-19 02:08:00.712 INFO 1 --- [ main] faultConfiguringBeanFactoryPostProcessor : No bean named 'errorChannel' has been explicitly defined.

안녕하세요, 이도원입니다. config-service에서 rabbitmq에 접속하지 못하는 원인은, 로그 메시지를 봤을 때 인증이 되지 않는 것 같습니다. rabbitmq의 로그인 정보에 문제가 있지 않았나 싶습니다. 기본 설치 시 guest/guest 이런 식으로 되어 있는데, 혹시 변경 사항이 있었는지 확인해 보시기 바랍니다. rabbitmq 서비스를 기동하신 뒤에 http://127.0.0.1:15672 으로 접속하셔서 인증이 되시는지 확인해 보시기 바랍니다. 감사합니다.
