SpringBoot 웹 서비스 - Github 작업 부분

GitHub Actions는 CI/CD를 저장소에 통합하는 원활한 방법을 제공하여 테스트 실행, 아티팩트 빌드, 프로젝트 배포와 같은 다양한 작업을 자동화합니다.

SNAPSHOT 워크플로

이 워크플로는 기본이 아닌 브랜치에서 또는 워크플로 발송 이벤트를 통해 수동으로 트리거됩니다. 여기에는 다음 단계가 포함됩니다.

• 테스트 실행: 코드가 모든 테스트를 통과하는지 확인합니다.
• JAR 파일 빌드: Spring Boot 애플리케이션을 컴파일합니다.
• Docker 이미지 빌드 및 GitHub Docker 레지스트리에 푸시: 생성된 아티팩트에서 Docker 이미지를 생성하여 GitHub Container Registry에 푸시합니다.

RELEASE 작업 흐름

이 워크플로는 변경 사항이 기본 분기에 푸시될 때 실행되며 다음 단계를 포함합니다.

• 릴리스 버전 빌드: 프로젝트의 릴리스 버전을 컴파일합니다.
• Docker 이미지를 빌드하여 GitHub Docker 레지스트리에 푸시: Docker 이미지를 생성하여 GitHub Container Registry에 푸시합니다.
• SNAPSHOT 버전 증가: 향후 스냅샷 버전을 위해 pom.xml의 버전을 업데이트합니다.
