안녕하세요. 저는 사내환경에서 학습을 진행하는 관계로 VM을 이용할 수 없는 상황입니다.windows에서 제공하는 wsl로 ubuntu를 띄워 터미널로만 진행해도 추후 학습 진행에 문제가 없을까요? 감사합니다.

안녕하세요 강사님 강의를 너무나도 재밌게 듣고 있는 학생입니다. 제가 윈도우 환경에서 하려다가 Ubuntu가 더 편해서 WSL를 사용해서 Ubuntu 환경에서 실습을 진행하고 있습니다. 그러던 중 애플리케이션 배포 -Docker Container 챕터에서 config-server를 도커 파일 만들고 배포하는 작업에서 에러가 발생합니다 문제는     docker run -d -p 8889:8889 --network ecommerce-network \ -e "spring.rabbitmq.host=rabbitmq" \ -e "spring.profiles.active=default" \ --name config-service youngkyonyou/config-service:1.0   (포트 8888 대신 8889를 사용함)   위 명령어를 -d 옵션을 빼고 실행해서 실행결과를 보여드리겠습니다.   여기까지 잘 실행되는 것 같으나 url로 접속할 때 문제가 생깁니다.   http://localhost:8889/ecommerce/default 로 접속하게 되면   위 사진과 같이 나오면서 로그가   /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.6.2) 2022-01-27 05:40:46.884 INFO 1 --- [ main] c.e.c.ConfigServiceApplication : The following profiles are active: default 2022-01-27 05:40:48.525 INFO 1 --- [ main] faultConfiguringBeanFactoryPostProcessor : No bean named 'errorChannel' has been explicitly defined.
