EC2 Instance를 구성하면서 매번 처음부터 세팅하고 번거로움을 줄이기 위하여 사용
EC2 User Data
- EC2 Instance
처음 부팅시 스크립트 자동으로 실행, 설정하는 기능 ( 재부팅 시 적용 되지 않는다. 만약 재부팅할 때 마다 적용하고 싶다면 아래에 별도로 소개 ) #!/bin/bash옵션을 주어야만 이를 인식하고 실행- 방화벽 해제 시 강제 옵션을 주지 않으면 실행 불가
자동 실행 목록
- Ubuntu 방화벽 해제
- ssh(22), 80, 8080(jenkins)
- Docker 설치 및 Jenkins+Python 환경 구성
- Dockerfile image build 및 Docker-compose 실행 ( restart 옵션 추가 )
- Codedeploy 설치

MIME
- EC2 Instance가 최초 실행뿐만 아니라 재부팅 시에도 Cloud init을 옵션을 통해 계속하여 실행
- User Init에 동일하게 추가하여 주면 된다.
- 재부팅 시 docker command가 막혀 옵션 추가
