pm2 명령을 사용하여 노드 서버를 내부적으로 트리거하는 perl 스크립트를 실행할 고정 된 도커 이미지가 작성되었습니다.종료하지 않고 도커 이미지 (nodejs 서버)를 실행하는 방법
이미지는 내가 명령 아래 사용하여 배경 이미지를 실행하면 스크립트를 실행하고,
FROM rm/node:4.0
EXPOSE 3000
EXPOSE 3030
EXPOSE 7030
WORKDIR /Reader_Manager/SISPlatform
CMD perl build_scripts/devdeploy.pl
dockerfile 사용하여 만들었습니다. 스크립트가 완료된 후에 스크립트는 종료됩니다.

Usage of loopback devices is strongly discouraged for production use. Either use `--storage-opt dm.thinpooldev` or use `--storage-opt dm.no_warn_on_loop_devices=true` to suppress this warning.

위에서 볼 수 있듯이 3 개의 포트가 있습니다. 하지만 perl 스크립트가 끝난 후에 종료됩니다. 다음은
