📃설명

appspec.yml

  • CodeDeploy Agent 가 수행할 작업과 환경을 설정하는 파일
  • source 는 CodeBuild 로 부터 전달받은 artifacts 의 파일 시스템 중 가져오고자 하는 파일
  • destination 은 배포하고자 하는 호스트(EC2) 의 파일 시스템에서 source 로부터 가져온 artifacts 가 위치할 디렉터리
version: 0.0
os: linux
files:
  - source: /
    destination: /home/ec2-user/app
hooks:
  AfterInstall:
    - location: scripts/pullDocker.sh
      timeout: 300
      runas: ec2-user
  ApplicationStart:
    - location: scripts/runDocker.sh
      timeout: 300

      timeout: 60
      runas: ec2-user

buildspec.dev.yml

  • CodeBuild 가 소스코드를 빌드할 때 수행할 작업과 환경을 설정하는 파일
  • phases 는 CodeBuild 에서 작업 단계를 나타내는 특수한 단계
  • artifacts 는 CodeBuild 가 작업을 마친 뒤 CodeDeploy 에게 전달할 파일들을 명시하는 부분으로, 여기서는 appspec.yml 과 docker 커맨드가 포함된 scripts/* , 그리고 docker-compose.dev.yml 파일을 전달
version: 0.1
phases:
  pre_build:
    commands:
      - 'echo Logging in to Docker Hub...'

    commands:
      - 'echo Build started on `date`'
      - 'echo Building the Docker image...'
      - 'docker-compose -f docker-compose.yml build'
  post_build:
    commands:
      - 'echo Build completed on `date`'
      - 'echo Pushing the Docker image...'
      - 'docker-compose -f docker-compose.yml push'
