+# Phonebill CI/CD 디렉토리 구조
+
+## 개요
+이 디렉토리는 Phonebill 마이크로서비스의 CI/CD 파이프라인을 위한 Kustomize 기반 구조를 포함합니다.
+
+## 디렉토리 구조
+
+```

+├── kustomize/
+│   ├── base/                     # Base 매니페스트 (환경 독립적)

+```
+
+## 주요 특징
+
+### 1. 네임스페이스 분리
+- **개발**: `phonebill-dev`
+- **스테이징**: `phonebill-staging`
+- **프로덕션**: `phonebill-prod`
+
+### 2. 환경별 리소스 설정
+- **개발**: 최소 리소스 (CPU: 250m, Memory: 512Mi)
+- **스테이징**: 중간 리소스, 복제본 2개
+- **프로덕션**: 최대 리소스, 복제본 3개
+
+### 3. 서비스 구성
+- **api-gateway**: API 게이트웨이
+- **user-service**: 사용자 인증/관리
+- **bill-service**: 요금 조회
+- **product-service**: 상품 변경
+- **kos-mock**: KOS 시스템 모킹
+
+## 사용 방법
+
+### 개발 환경 배포
+```bash
+kubectl apply -k deployment/cicd/kustomize/overlays/dev
+```
+
+### 스테이징 환경 배포
+```bash
+kubectl apply -k deployment/cicd/kustomize/overlays/staging
+```
+
+### 프로덕션 환경 배포
+```bash
+kubectl apply -k deployment/cicd/kustomize/overlays/prod
+```
+
+### 매니페스트 미리보기
+```bash
+kubectl kustomize deployment/cicd/kustomize/overlays/dev
+```
+
+## 주요 변경사항
+1. 기존 `deployment/k8s/` 매니페스트를 `base/`로 복사
+2. 하드코딩된 네임스페이스 제거 (`phonebill-dev`)
+3. 환경별 오버레이 구조 적용
+4. 리소스 제한 및 복제본 수 환경별 차별화

+# Jenkins CI/CD Pipeline 구축 가이드
+
+## 📋 개요
+
+phonebill 마이크로서비스를 위한 Jenkins CI/CD 파이프라인 구축 가이드입니다.
+Azure Kubernetes Service(AKS)와 Azure Container Registry(ACR)를 활용한 자동화된 배포 시스템을 구성합니다.
+
+## 🏗️ 아키텍처
+
+### 시스템 구성요소
+- **Jenkins**: CI/CD 오케스트레이션
+- **Azure Container Registry (ACR)**: 컨테이너 이미지 저장소
+- **Azure Kubernetes Service (AKS)**: 컨테이너 오케스트레이션
+- **SonarQube**: 코드 품질 분석
+- **Gradle**: 빌드 도구
+- **Kustomize**: Kubernetes 매니페스트 관리
+
+### 배포 환경
+- **Development** (`phonebill-dev`)
+- **Staging** (`phonebill-staging`)
+- **Production** (`phonebill-prod`)
+
+## 🚀 파이프라인 워크플로우
+
+```mermaid
+graph LR
+    A[Code Commit] --> B[Jenkins Trigger]
+    B --> C[Build & Test]
+    C --> D[SonarQube Analysis]
+    D --> E[Quality Gate]
+    E --> F[Container Build]
+    F --> G[Push to ACR]
+    G --> H[Deploy to AKS]
+    H --> I[Health Check]
+    I --> J[Notification]
+```
+
+### 주요 단계
+
+1. **Initialize**: 환경별 설정 로드 및 파라미터 설정
+2. **Checkout & Prepare**: 소스 코드 체크아웃 및 빌드 태그 생성
+3. **Build & Test**: Gradle을 이용한 빌드 및 단위 테스트
+4. **SonarQube Analysis**: 코드 품질 분석
+5. **Quality Gate**: 품질 기준 검증
+6. **Container Build & Push**: 컨테이너 이미지 빌드 및 ACR 푸시
+7. **Deploy to Kubernetes**: AKS 클러스터에 배포
+8. **Health Check**: 배포된 서비스 상태 확인
+

+```
+
+## 🔧 Jenkins 구성
+
+### 1. Jenkins 플러그인 설치
+
+필수 플러그인 목록:
+```bash
+# Kubernetes 관련
+Kubernetes Plugin
+Pipeline: Kubernetes Steps
+
+# Azure 관련
+Azure CLI Plugin
+Azure Container Registry Plugin
+
+# 빌드 도구

+
+### 2. 글로벌 설정
+
+#### Azure Service Principal 설정
+```bash
+# Jenkins 관리 > 시스템 설정 > Global properties
+# Environment variables 추가
+AZURE_TENANT_ID=<your-tenant-id>
+AZURE_SUBSCRIPTION_ID=<your-subscription-id>
+```
+
+#### Credentials 설정
+Jenkins 관리 > Manage Credentials에서 다음 설정:
+
+1. **azure-service-principal** (Azure Service Principal)
+   - ID: `azure-service-principal`
+   - Type: Microsoft Azure Service Principal
+   - Tenant ID: Azure 테넌트 ID
+   - Client ID: 서비스 프린시pal 클라이언트 ID
+   - Client Secret: 서비스 프린시pal 시크릿
+
+2. **acr-credentials** (ACR 인증 정보)
+   - ID: `acr-credentials`
+   - Type: Username with password
+   - Username: ACR 사용자명
+   - Password: ACR 패스워드
+
+3. **sonarqube-token** (SonarQube 토큰)
+   - ID: `sonarqube-token`
+   - Type: Secret text
+   - Secret: SonarQube 액세스 토큰
+
+4. **slack-token** (Slack 토큰)
+   - ID: `slack-token`
+   - Type: Secret text

+
+### 3. Kubernetes Agent 설정
+
+Jenkins가 Kubernetes 클러스터에서 빌드 에이전트를 실행할 수 있도록 설정:
+
+#### ServiceAccount 및 RBAC 생성
+```yaml
+# jenkins-rbac.yaml
+apiVersion: v1
+kind: ServiceAccount
+metadata:
+  name: jenkins-agent
+  namespace: jenkins
+---
+apiVersion: rbac.authorization.k8s.io/v1
+kind: ClusterRole
+metadata:
+  name: jenkins-agent
+rules:
+- apiGroups: [\"\"]
+  resources: [\"pods\", \"pods/exec\", \"pods/log\", \"persistentvolumeclaims\"]
+  verbs: [\"*\"]
+- apiGroups: [\"apps\"]
+  resources: [\"deployments\", \"replicasets\"]
+  verbs: [\"*\"]
+---
+apiVersion: rbac.authorization.k8s.io/v1
+kind: ClusterRoleBinding
+metadata:
+  name: jenkins-agent
+roleRef:
+  apiGroup: rbac.authorization.k8s.io
+  kind: ClusterRole
+  name: jenkins-agent
+subjects:
+- kind: ServiceAccount
+  name: jenkins-agent
+  namespace: jenkins
+```
+
+#### Gradle Cache PVC 생성
+```yaml

+### 4. SonarQube 설정
+
+#### SonarQube Server 구성
+Jenkins 관리 > Configure System > SonarQube servers:
+- Name: `SonarQube`
+- Server URL: `http://sonarqube.example.com`
+- Server authentication token: `sonarqube-token` credential 선택
+
+## 🔨 파이프라인 생성
+
+### 1. 새 Pipeline Job 생성
+1. Jenkins 대시보드에서 \"New Item\" 클릭
+2. Job 이름: `phonebill-pipeline`
+3. Type: \"Pipeline\" 선택
+4. OK 클릭
+
+### 2. Pipeline 설정
+1. **General** 탭:
+   - Description: \"phonebill microservices CI/CD pipeline\"
+   - \"GitHub project\" 체크하고 프로젝트 URL 입력
+
+2. **Build Triggers** 탭:
+   - \"GitHub hook trigger for GITScm polling\" 체크 (GitHub Webhook 사용 시)
+   - \"Poll SCM\" 설정: `H/5 * * * *` (5분마다 폴링)
+
+3. **Pipeline** 탭:
+   - Definition: \"Pipeline script from SCM\"
+   - SCM: Git
+   - Repository URL: GitHub 저장소 URL
+   - Credentials: GitHub 인증 정보
+   - Branch: `*/main`
+   - Script Path: `deployment/cicd/Jenkinsfile`
+
+### 3. 환경별 파이프라인 생성
+동일한 방식으로 환경별 파이프라인 생성:
+- `phonebill-dev-pipeline`
+- `phonebill-staging-pipeline`
+- `phonebill-prod-pipeline`
+
+## 🧪 파이프라인 실행
+
+### 1. 수동 실행
+1. Jenkins에서 파이프라인 Job 선택
+2. \"Build with Parameters\" 클릭
+3. 파라미터 설정:
+   - **ENVIRONMENT**: `dev` / `staging` / `prod`
+   - **SERVICES_TO_BUILD**: `all` 또는 특정 서비스
+   - **SKIP_TESTS**: 테스트 스킵 여부
+   - **SKIP_SONAR**: SonarQube 분석 스킵 여부
+   - **FORCE_DEPLOY**: 강제 배포 여부
+4. \"Build\" 클릭
+
+### 2. 자동 실행 (Webhook)
+GitHub에서 코드 푸시 시 자동으로 파이프라인이 트리거됩니다.
+
+#### GitHub Webhook 설정
+1. GitHub 저장소 > Settings > Webhooks
+2. Add webhook:
+   - Payload URL: `http://jenkins.example.com/github-webhook/`
+   - Content type: `application/json`
+   - Secret: 설정한 시크릿
+   - Events: \"Just the push event\"
+
+## 📊 모니터링 및 알림
+
+### 1. 빌드 상태 모니터링
+- Jenkins Blue Ocean 인터페이스 활용
+- 파이프라인 실행 상태 실시간 확인
+- 로그 및 아티팩트 확인
+
+### 2. 알림 설정
+파이프라인 실행 결과를 다음 채널로 알림:
+- **Slack**: 지정된 채널에 빌드 상태 알림
+- **Email**: 담당자에게 결과 메일 발송
+
+### 3. 메트릭 수집
+- 빌드 시간 추적
+- 성공/실패율 모니터링
+- 배포 빈도 측정
+
+## 🔍 트러블슈팅
+
+### 일반적인 문제 해결
+
+#### 1. Azure 인증 실패
+```bash
+# 서비스 프린시pal 권한 확인
+az role assignment list --assignee <service-principal-client-id>
+
+# 필요한 권한 할당
+az role assignment create \
+  --assignee <service-principal-client-id> \
+  --role \"AKS Cluster Admin\" \
+  --scope /subscriptions/<subscription-id>/resourceGroups/<rg-name>
+```
+
+#### 2. ACR 푸시 실패
+```bash
+# ACR 로그인 확인
+az acr login --name <acr-name>
+
+# ACR 권한 확인
+az acr show --name <acr-name> --resource-group <rg-name>
+```
+
+#### 3. Kubernetes 배포 실패
+```bash
+# kubectl 컨텍스트 확인
+kubectl config current-context
+
+# 네임스페이스 확인
+kubectl get namespaces
+
+# 리소스 상태 확인
+kubectl get all -n <namespace>
+```
+
+#### 4. 파드 시작 실패
+```bash
+# 파드 로그 확인
+kubectl logs <pod-name> -n <namespace>
+
+# 파드 상세 정보 확인
+kubectl describe pod <pod-name> -n <namespace>
+
+# 이벤트 확인
+kubectl get events -n <namespace> --sort-by='.lastTimestamp'
+```
+
+### 로그 위치
+- **Jenkins 로그**: `/var/log/jenkins/jenkins.log`
+- **파이프라인 로그**: Jenkins UI에서 Build History > Console Output
+- **Kubernetes 로그**: `kubectl logs` 명령어 사용
+
+## 🚀 수동 배포 스크립트 사용법
+
+Jenkins 파이프라인 외에도 수동 배포 스크립트를 제공합니다.
+
+### 기본 사용법
+```bash
+# 모든 서비스를 dev 환경에 배포
+./deployment/cicd/scripts/deploy.sh dev
+
+# 특정 서비스만 staging 환경에 배포
+./deployment/cicd/scripts/deploy.sh staging user-service
+
+# 여러 서비스를 prod 환경에 배포
+./deployment/cicd/scripts/deploy.sh prod api-gateway,user-service,bill-service
+
+# 옵션 사용 예시
+./deployment/cicd/scripts/deploy.sh dev all --skip-build --skip-test
+```
+
+### 주요 옵션
+- `--skip-build`: Gradle 빌드 스킵
+- `--skip-test`: 단위 테스트 스킵
+- `--skip-push`: 컨테이너 이미지 푸시 스킵
+- `--force`: 변경사항이 없어도 강제 배포
+- `--dry-run`: 실제 배포 없이 미리보기
+
+## 📈 성능 최적화
+
+### 1. 빌드 성능 개선
+- **Gradle Daemon** 활용: `--daemon` 옵션
+- **병렬 빌드**: `--parallel` 옵션
+- **Build Cache** 활용: `--build-cache` 옵션
+- **Incremental Build** 활용
+
+### 2. 컨테이너 이미지 최적화
+- **Multi-stage Build** 사용
+- **Layer Caching** 최적화
+- **Base Image** 최적화
+- **.dockerignore** 활용
+
+### 3. Kubernetes 배포 최적화
+- **Rolling Update** 전략 사용
+- **Resource Limits** 설정
+- **Readiness/Liveness Probe** 설정
+- **Pod Disruption Budget** 설정
+
+## 🔒 보안 고려사항
+
+### 1. 인증 및 권한 관리
+- Azure Service Principal 최소 권한 원칙
+- Jenkins Credentials 암호화 저장
+- Kubernetes RBAC 적절한 권한 할당
+- 시크릿 정보 환경 변수로 분리
+
+### 2. 컨테이너 보안
+- 취약점 스캐닝 도구 통합
+- 비특권 사용자로 컨테이너 실행
+- 읽기 전용 루트 파일시스템
+- 보안 컨텍스트 설정
+
+### 3. 네트워크 보안
+- Private Registry 사용
+- Network Policy 적용
+- Service Mesh 보안 정책
+- TLS/SSL 암호화
+
