ECS CICD Automation - 7. Jenkins Job (ECS Fargate Rolling)

이전 ECS 배포 잡을 카피해서 만들어 줍시다.

 

 

변수는 아래와 같이 수정해줍니다.

 

 

그리고 스크립트를 아래와 같이 넣어주세요

배포는 뭐 크게 문제가 없습니다

 

잘 수행된 것을 볼 수 있습니다.

 

 

배포가 수행되고, CLI를 통해 서비스가 새롭게 뜬 것을 볼 수 있습니다.

 

 

 

새롭게 타겟그룹에도 파게이트 컨테이너가 띄워지고,

 

 

 

러닝까지 잘 수행된 다음 헬스체크도 잘 되는것을 볼 수 있습니다.

 

 

 

URL로 접속 시에도 문제가 없는 것을 볼 수 있습니다.

 

 

다음 포스트에서는 Blue Green 배포에 대해 알아보도록 하겠습니다.
