git action - ECS 배포 자동화

배포를 자동화할 ECS 작업 테스크의 JSON파일을 가져온다.

task-definition.json 파일을 프로젝트 폴더안으로 옮긴다.

나는 프로젝트폴더 최상위 폴더에 aws폴더를 만들어서 넣어줬다.

깃액션 yml 작성

프로젝트 폴더 최상위에 /github/workflows/deploy-ecr.yml 파일을 만들어준다.

env에 설정된 값은 다음과 같다.

• AWS_REGION: ap-northeast-2
  • 사용하고 있는 aws region이다.
• ECR_REGISTRY: 725601756882.dkr.ecr.ap-northeast-2.amazonaws.com
  • ecr의 registry이다 이미지의 앞부분
• ECR_REPOSITORY: mildstone-backend
  • ecr의 repository이다 이미지의 뒷부분
• ECS_SERVICE: fastify-sv
  • 배포할 서비스의 이름
• ECS_CLUSTER: mongo-cluster
  • 배포할 클러스터이름
• ECS_TASK_DEFINITION: ./aws/task-definition.json
  • 사용할 task-definition의 위치
• CONTAINER_NAME: fastify
  • task-definition.json에서 containerDefinitions -> name을 가져 온다.
