나는 ECS Getting Started tutorial을 따라 갔으나 ECS 에이전트가 컨테이너를 시작하지 못했습니다. 같은 인스턴스에서 수동으로 이미지를 시작하면 시작됩니다.ECS 에이전트 시작 도커 컨테이너가 완료되지 않습니다. 수동 시작 성공
이미지는 /에서 단일 끝 점이있는 Spring Boot 웹 응용 프로그램이며 "Hello world !!"라는 문자열을 반환합니다. 컨테이너는 로컬에서 잘 실행되며 내가 만든 CentOS EC2 인스턴스에서도 제대로 실행됩니다. 엔드 포인트는 CentOS EC2 인스턴스에서 도커 이미지를 실행할 때 공개적으로 사용할 수 있습니다.
ECS 인스턴스에는 마법사에서 만든 보안 그룹이 있으며 포트 80이 열려 있습니다. SSH 액세스를 위해 포트 22를 추가했습니다.
ECS 인스턴스에서 SSH를 실행하여 컨테이너에 대한 Docker 로그를 볼 때 엔트리 포인트 실행 중에 걸려있는 것처럼 보입니다. 여기
은 부두 노동자에 매달려 예를 들어 로그입니다 : 내 컨테이너 이미지에서 응용 프로그램 오류 것 같아 처음에는

,하지만 난 고정 표시기 프로세스를 중지하고, 수동으로 출력을 동일한 이미지를 실행할 때 기대 한대로 인스턴스 외부에서 내 끝점에 연결할 수 있습니다.

ECS 에이전트가 내 응용 프로그램을 시작하지 못하는 이유는 무엇입니까?

ECS가 실행될 때 컨테이너가 시작되는 방법과 수동으로 컨테이너를 시작할 때 시작되는 방식이 다를 수 있습니다. ** ECS Task Definition ** JSON을 게시 할 수 있습니까? –
안녕하세요 @ JohananLieberman 작업 정의를 추가했습니다. 감사합니다 – BenR
