다시 한번 말하지만, 폴더명에 띄어쓰기 넣지마라....^^....
매번 따옴표 써주기 귀찮다.
이미지를 실행시켜서 컨테이너화된 애플리케이션이 제대로 작동하는지 확인.
docker run --rm --name catalog-service -p 8080:8080 catalog-service:0.0.1-SNAPSHOT
| 명령어 | 의미 |
| docker run | 이미지에서 컨테이너를 실행 |
| --rm | 실행이 끝난 후 컨테이너를 삭제 |
| --name catalog-service | 컨테이너 이름 |
| -p 8080:8080 | 포트번호 8080을 통해 컨테이너 외부로 서비스를 노출 |
| catalog-service:0.0.1-SNAPSHOT | 실행할 이미지의 이름과 버전 |
제대로 실행됐다! (사실 중간에 명령어 잘못치는 바람에 계속안되서 잠시 화날 뻔했으나 빠른 해결)
확인 후 ctrl c 눌러 컨테이너 종료
