Docker + Github Actions + SpringBoot CI 구축

GitHub Actions를 사용하여 리포지토리에서 바로 소프트웨어 개발 워크플로를 자동화, 사용자 지정 및 실행 가능하며, CI/CD를 포함하여 원하는 작업을 수행하기 위한 작업을 검색, 생성 및 공유하고 완전히 사용자 정의된 워크플로에서 작업을 결합 할 수 있다.

방법

1. Github action을 사용한 CI 구축

• Java with Gradle Workflow 작성
  

🏳️ 빌드시 테스트에서 에러 발생시 빌드가 정상적으로 이루어지지 않을 수 있어, 테스트를 제외한 후 빌드

 ./gradlew clean build --exclude-task test 

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.
# This workflow will build a Java project with Gradle and cache/restore any dependencies to improve the workflow execution time
# For more information see: https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-java-with-gradle

1. Github Action를 통한 CI
2. Application Build
3. Docker image Build
4. Docker login
5. Docker image Push (docker hub push)
