[Jenkins] CI

1. Jenkins 관리 > Plugins > Available plugins에서 GitLab을 검색해서 설치 

 

2. Jenkins 관리 > System에 GitLab 설정

• 발급받은 GitLab API token을 넣는다.
• Credentials를 추가 후 목록에서 선택까지 해줘야 한다.
• Test connection이 success로 뜨면 성공이다.

Credentials > Add > Jenkins

 

 

3. Jenkins 관리 > Credentials에 GitLab 아이디, 비밀번호 등록

• Username: GitLab 아이디
• Password: GitLab 비밀번호
• ID: 스크립트 작성할 때 credentialsId

 

 

4. Pipeline 스크립트 작성

• 입력한 레포지토리의 develop-music 브랜치에서 credentailsId로 등록된 정보를 이용하여 클론 받기
• root 디렉토리 아래에 있는 back 폴더에서 빌드

pipeline {
    agent any
    
    stages {
        stage('clone') { 
            steps {
                git branch: 'develop-music', credentialsId: '{등록한 credentail id 입력}', url: '{레포지토리 주소 입력}'}
        }
    
        stage('build') { 
             steps {
                dir("./back") {
                     script {
                        sh "chmod +x gradlew"
                        sh "./gradlew build --info"
                    }
                }
            }
        }
        
    }
}
