+# phonebill Jenkins CI/CD 파이프라인 구축 가이드
+
+## 📋 개요
+
+본 가이드는 phonebill 프로젝트를 위한 Jenkins + Kustomize 기반 CI/CD 파이프라인 구축 방법을 제공합니다.
+
+### 프로젝트 정보
+- **시스템명**: phonebill
+- **서비스 목록**: api-gateway, user-service, bill-service, product-service, kos-mock
+- **JDK 버전**: 21
+- **Azure 환경**:
+  - ACR: acrdigitalgarage01
+  - 리소스 그룹: rg-digitalgarage-01
+  - AKS 클러스터: aks-digitalgarage-01
+  - 네임스페이스: phonebill-dg0500
+
+## 🏗️ 파이프라인 아키텍처
+
+### 주요 구성 요소
+- **빌드**: Gradle 기반 멀티모듈 빌드
+- **품질 검증**: SonarQube 분석 & Quality Gate
+- **컨테이너화**: Podman 기반 이미지 빌드
+- **배포**: Kustomize를 통한 환경별 배포
+- **인프라**: AKS (Azure Kubernetes Service)
+
+### 환경별 설정
+| 환경 | Replicas | CPU Request | Memory Request | CPU Limit | Memory Limit |
+|------|----------|-------------|----------------|-----------|--------------|
+| dev | 1 | 256m | 256Mi | 1024m | 1024Mi |
+| staging | 2 | 512m | 512Mi | 2048m | 2048Mi |
+| prod | 3 | 1024m | 1024Mi | 4096m | 4096Mi |
+
+## 🚀 Jenkins 서버 환경 구성
+
+### 1. Jenkins 필수 플러그인 설치
+
+Jenkins 관리 > Plugin Manager에서 다음 플러그인들을 설치해주세요:
+
+```bash
+# Jenkins 필수 플러그인 목록
+- Kubernetes
+- Pipeline Utility Steps
+- Docker Pipeline
+- GitHub
+- SonarQube Scanner
+- Azure Credentials
+```
+
+### 2. Jenkins Credentials 등록
+
+**Manage Jenkins > Credentials > Add Credentials**에서 다음 인증 정보들을 등록해주세요:
+
+#### Azure Service Principal
+```
+Kind: Microsoft Azure Service Principal
+ID: azure-credentials
+Subscription ID: {구독ID}
+Client ID: {클라이언트ID}
+Client Secret: {클라이언트시크릿}
+Tenant ID: {테넌트ID}
+Azure Environment: Azure
+```
+
+#### ACR Credentials
+```
+Kind: Username with password
+ID: acr-credentials
+Username: acrdigitalgarage01
+Password: {ACR_PASSWORD}
+```
+
+#### Docker Hub Credentials (Rate Limit 해결용)
+```
+Kind: Username with password
+ID: dockerhub-credentials
+Username: {DOCKERHUB_USERNAME}
+Password: {DOCKERHUB_PASSWORD}
+참고: Docker Hub 무료 계정 생성 (https://hub.docker.com)
+```
+
+#### SonarQube Token
+```
+Kind: Secret text
+ID: sonarqube-token
+Secret: {SonarQube토큰}
+```

+3. **Build** 클릭
+
+### 2. 수동 배포 (스크립트 사용)
+```bash
+# 개발 환경 배포
+./deployment/cicd/scripts/deploy.sh dev 20241230120000
+
+# 스테이징 환경 배포
+./deployment/cicd/scripts/deploy.sh staging 20241230120000
+
+# 운영 환경 배포
+./deployment/cicd/scripts/deploy.sh prod 20241230120000
+```
+
+### 3. 배포 상태 확인
+```bash
+# Pod 상태 확인
+kubectl get pods -n phonebill-dg0500
+
+# 서비스 상태 확인
+kubectl get services -n phonebill-dg0500
+
+# Ingress 상태 확인
+kubectl get ingress -n phonebill-dg0500
+
+# 특정 서비스 로그 확인
+kubectl logs -f deployment/user-service -n phonebill-dg0500
+```
+
+## 🔍 리소스 검증
+
+### 리소스 검증 스크립트 실행
+```bash
+# 모든 Kustomize 리소스 검증
+./deployment/cicd/scripts/validate-resources.sh
+```
+
+### 수동 검증 명령어
+```bash
+# Base 검증
+kubectl kustomize deployment/cicd/kustomize/base/
+
+# 환경별 검증
+kubectl kustomize deployment/cicd/kustomize/overlays/dev/
+kubectl kustomize deployment/cicd/kustomize/overlays/staging/
+kubectl kustomize deployment/cicd/kustomize/overlays/prod/
+```
+
+## 🔄 롤백 방법
+
+### 1. Kubernetes 롤백
+```bash
+# 특정 버전으로 롤백
+kubectl rollout undo deployment/{서비스명} -n phonebill-dg0500 --to-revision=2
+
+# 롤백 상태 확인
+kubectl rollout status deployment/{서비스명} -n phonebill-dg0500
+```
+
+### 2. 이미지 태그 기반 롤백
+```bash
+# 이전 안정 버전 이미지 태그로 업데이트
+cd deployment/cicd/kustomize/overlays/{환경}
+kustomize edit set image acrdigitalgarage01.azurecr.io/phonebill/{서비스명}:{환경}-{이전태그}
+kubectl apply -k .
+```
+
+## 🎯 파이프라인 단계별 설명
+
+### 1. Get Source
+- Git 저장소에서 소스코드 체크아웃
+- 환경별 설정 파일 로드
+
+### 2. Setup AKS
+- Azure CLI를 통한 AKS 클러스터 연결
+- 네임스페이스 생성 (phonebill-dg0500)
+
+### 3. Build
+- Gradle을 통한 멀티모듈 빌드
+- 테스트는 SonarQube 단계에서 실행
+
+### 4. SonarQube Analysis & Quality Gate
+- 각 서비스별 개별 테스트 실행
+- JaCoCo 코드 커버리지 리포트 생성
+- SonarQube 정적 분석
+- Quality Gate 통과 검증
+
+### 5. Build & Push Images
+- Podman을 통한 컨테이너 이미지 빌드
+- 환경별 태그로 ACR에 푸시
+- 30분 타임아웃 설정
+
+### 6. Update Kustomize & Deploy
+- Kustomize를 통한 이미지 태그 업데이트
+- 환경별 매니페스트 적용
+- 배포 완료까지 대기 (5분 타임아웃)
+
+### 7. Pipeline Complete
+- 파이프라인 완료 상태 로깅
+- Pod 자동 정리 (3초 후 종료)
+
+## ⚠️ 주의사항
+
+### 1. 파드 자동 정리
+- 파이프라인 완료 시 에이전트 파드 자동 삭제
+- `podRetention: never()` 설정으로 즉시 정리
+- 리소스 절약을 위한 필수 설정
+
+### 2. 변수 참조 문법
+- Jenkins Groovy에서는 `${variable}` 사용
+- `\${variable}` 사용 시 "syntax error: bad substitution" 오류 발생
+
+### 3. 쉘 호환성
+- Jenkins 컨테이너 기본 쉘이 `/bin/sh`인 경우
+- Bash 배열 문법 `()` 미지원으로 공백 구분 문자열 사용
+
+### 4. 환경별 설정 차이점
+- **DEV**: SSL 리다이렉트 비활성화, 기본 도메인 사용
+- **STAGING/PROD**: SSL 리다이렉트 활성화, 사용자 정의 도메인, 인증서 설정
+
+## 🛠️ 트러블슈팅
+
+### 1. 빌드 실패
+```bash
+# Gradle 캐시 클리어
+./gradlew clean build
+
+# JDK 버전 확인
+java -version
+```
+
+### 2. 이미지 푸시 실패
+```bash
+# ACR 로그인 확인
+az acr login --name acrdigitalgarage01
+
+# Docker Hub rate limit 확인
+docker info | grep -i rate
+```
+
+### 3. 배포 실패
+```bash
+# 네임스페이스 확인
+kubectl get namespaces
+
+# 리소스 상태 확인
+kubectl describe deployment/{서비스명} -n phonebill-dg0500
+```
+
+### 4. SonarQube 분석 실패
+- SonarQube 서버 연결 상태 확인
+- 토큰 유효성 검증
+- Quality Gate 설정 확인
+
+## 📈 모니터링 및 로그
+
+### 1. Jenkins 빌드 히스토리
+- 각 단계별 실행 시간 추적
+- 실패 단계 및 원인 분석
+
+### 2. 애플리케이션 로그
+```bash
+# 실시간 로그 모니터링
+kubectl logs -f deployment/{서비스명} -n phonebill-dg0500
+
+# 특정 기간 로그 확인
+kubectl logs deployment/{서비스명} -n phonebill-dg0500 --since=1h
+```
+
+### 3. 성능 메트릭
+- Kubernetes 메트릭 서버 활용
+- 각 서비스별 리소스 사용량 모니터링
+
+---
+
+## 📞 지원
+
+문의사항이나 문제 발생 시:
+1. Jenkins 빌드 로그 확인
+2. Kubernetes 이벤트 확인: `kubectl get events -n phonebill-dg0500`
+3. 리소스 검증 스크립트 실행: `./deployment/cicd/scripts/validate-resources.sh`
+
