-## ⚠️ 주의사항 및 체크리스트 준수사항
+### ⚙️ 스크립트 및 설정
+- [x] 환경별 설정 파일 작성 (dev/staging/prod)
+- [x] Jenkinsfile 작성 (JDK21, 파드 자동 정리 포함)
+- [x] 수동 배포 스크립트 작성 및 실행 권한 설정
+- [x] 검증 스크립트 작성 및 실행 권한 설정

-### 🚨 **체크리스트 핵심 준수사항**
+## 🎯 다음 단계

-#### **1. Ingress 설정 규칙** ⚠️ **매우 중요**
-```yaml
-# ✅ DEV 환경: base와 동일한 host 사용
- host: phonebill-api.20.214.196.128.nip.io  # base와 동일해야 함!
+1. **Jenkins 서버 설정**
+   - 필수 플러그인 설치
+   - Credentials 등록 (azure, acr, dockerhub, sonarqube)

-# ✅ STAGING/PROD: 환경별 도메인 사용
- host: phonebill.staging-domain.com    # staging
- host: phonebill.production-domain.com # prod
-```
+2. **SonarQube 연동**
+   - 서비스별 프로젝트 생성
+   - Quality Gate 규칙 설정

-#### **2. Patch 파일 작성 원칙**
- ❌ **금지**: base 매니페스트에 없는 항목 추가
- ✅ **필수**: base 매니페스트와 항목 구조 일치
- ✅ **필수**: Secret에 `stringData` 사용 (`data` 금지)
- ✅ **필수**: `patches` 사용 (`patchesStrategicMerge` 금지)
+3. **파이프라인 테스트**
+   - 개발 환경 배포 테스트
+   - 스테이징/운영 환경 배포 준비

-#### **3. Deployment Patch 필수 항목**
-```yaml
-# ✅ 반드시 포함해야 할 항목들
-spec:
-  replicas: {환경별설정}  # dev:1, staging:2, prod:3
-  template:
-    spec:
-      containers:
-      - resources:  # 반드시 포함
-          requests: {환경별설정}
-          limits: {환경별설정}
-```
-
-#### **4. Jenkinsfile 검증 포인트**
- ✅ JDK 버전: `gradle:jdk21` (프로젝트 JDK와 일치)
- ✅ 서비스 배열: `['api-gateway', 'user-service', 'bill-service', 'product-service', 'kos-mock']`
- ✅ 변수 문법: `${variable}` (⚠️ `\${variable}` 금지)
- ✅ ACR 이름: `acrdigitalgarage01` (실행정보와 일치)
-
-### 🔍 **배포 전 필수 검증**
-
-#### **파일 구조 검증**
-```bash
-# 모든 환경별 파일이 존재하는지 확인
-find deployment/cicd/kustomize/overlays -name "*.yaml" | wc -l
-# 결과: 36개 파일이 있어야 함 (각 환경별 12개씩)
-```
-
-#### **Kustomize 빌드 테스트**
-```bash
-# 각 환경별 매니페스트 빌드 테스트
-kubectl kustomize deployment/cicd/kustomize/overlays/dev
-kubectl kustomize deployment/cicd/kustomize/overlays/staging  
-kubectl kustomize deployment/cicd/kustomize/overlays/prod
-# 모두 오류 없이 빌드되어야 함
-```
-
-#### **base vs dev ingress 비교**
-```bash
-# DEV 환경이 base와 동일한 host를 사용하는지 확인
-diff deployment/cicd/kustomize/base/common/ingress.yaml deployment/cicd/kustomize/overlays/dev/ingress-patch.yaml
-# host 라인에서 차이가 없어야 함
-```
-
-### 🛡️ **보안 및 운영**
-
-#### **보안 체크**
- 모든 `change-in-production` 패스워드를 실제 값으로 변경
- 프로덕션 환경 도메인 설정 확인
- SSL 인증서 설정 검증
- JWT Secret 키 프로덕션 전용으로 변경
-
-#### **성능 모니터링**
- 각 환경별 리소스 할당량 모니터링
- 배포 시 트래픽 영향도 확인
- Pod 리소스 사용량 추적
-
-#### **운영 모니터링**
- 배포 후 서비스 상태 확인
- 로그 및 메트릭 모니터링
- 헬스체크 엔드포인트 확인
-
-## 🆘 문제 해결 및 실수 방지
-
-### **자주 발생하는 실수들**
-
-#### **🚨 1. Ingress Host 실수**
-**문제**: DEV 환경에서 host를 `phonebill-dev-api.xxx`로 변경
-**해결**: DEV는 반드시 base와 동일한 host 사용
-```bash
-# 실수 방지 검증 명령
-grep "host:" deployment/cicd/kustomize/base/common/ingress.yaml
-grep "host:" deployment/cicd/kustomize/overlays/dev/ingress-patch.yaml
-# 두 결과가 동일해야 함
-```
-
-#### **🚨 2. Secret에서 data 사용 실수**
-**문제**: `data` 필드 사용으로 base64 인코딩 필요
-**해결**: 항상 `stringData` 사용
-```yaml
-# ❌ 잘못된 방법
-data:
-  DB_PASSWORD: "cGFzc3dvcmQ="  # base64 인코딩 필요
-
-# ✅ 올바른 방법  
-stringData:
-  DB_PASSWORD: "password"      # 평문 직접 입력
-```
-
-#### **🚨 3. Deployment Patch 누락 항목**
-**문제**: replicas나 resources 누락으로 기본값 사용
-**해결**: 반드시 환경별 설정 포함
-```yaml
-# ✅ 필수 포함 항목
-spec:
-  replicas: 1  # 반드시 명시
-  template:
-    spec:
-      containers:
-      - resources:  # 반드시 포함
-          requests:
-            cpu: 256m
-            memory: 256Mi
-          limits:
-            cpu: 1024m

-```
-
-#### **🚨 4. Jenkinsfile 변수 문법 실수**
-**문제**: `\${variable}` 사용으로 "syntax error: bad substitution" 발생
-**해결**: Jenkins Groovy에서는 `${variable}` 사용
-```groovy
-# ❌ 잘못된 문법
-sh "echo \${environment}"
-
-# ✅ 올바른 문법
-sh "echo ${environment}"
-```
-
-### **Docker Hub 계정이 없는 경우 대안**
-
-Docker Hub 계정 생성이 어려운 경우, 다음과 같이 Jenkinsfile을 수정할 수 있습니다:
-
-```groovy
-// 수정 전 (Docker Hub 로그인 포함)
-withCredentials([
-    usernamePassword(
-        credentialsId: 'acr-credentials',
-        usernameVariable: 'ACR_USERNAME',
-        passwordVariable: 'ACR_PASSWORD'
-    ),
-    usernamePassword(
-        credentialsId: 'dockerhub-credentials',
-        usernameVariable: 'DOCKERHUB_USERNAME', 
-        passwordVariable: 'DOCKERHUB_PASSWORD'
-    )
-]) {
-    sh "podman login docker.io --username \$DOCKERHUB_USERNAME --password \$DOCKERHUB_PASSWORD"
-    sh "podman login acrdigitalgarage01.azurecr.io --username \$ACR_USERNAME --password \$ACR_PASSWORD"
-    // ...
-}
-
-// 수정 후 (Docker Hub 로그인 제거)
-withCredentials([usernamePassword(
-    credentialsId: 'acr-credentials',
-    usernameVariable: 'ACR_USERNAME',
-    passwordVariable: 'ACR_PASSWORD'
-)]) {
-    sh "podman login acrdigitalgarage01.azurecr.io --username \$ACR_USERNAME --password \$ACR_PASSWORD"
-    // ...
-}
-```
-
-**⚠️ 주의**: Docker Hub 로그인을 제거하면 pull rate limit에 걸릴 수 있습니다.
-
-### **배포 전 최종 검증 스크립트**
-```bash
-#!/bin/bash
-echo "🔍 Jenkins CI/CD 구성 최종 검증 시작..."
-
-# 1. 파일 개수 확인
-echo "1. 파일 개수 검증..."
-OVERLAY_FILES=$(find deployment/cicd/kustomize/overlays -name "*.yaml" | wc -l)
-if [ $OVERLAY_FILES -eq 36 ]; then
-    echo "✅ Overlay 파일 개수 정상 (36개)"
-else
-    echo "❌ Overlay 파일 개수 오류 ($OVERLAY_FILES개, 36개여야 함)"
-fi
-
-# 2. DEV ingress host 검증
-echo "2. DEV Ingress Host 검증..."
-BASE_HOST=$(grep "host:" deployment/cicd/kustomize/base/common/ingress.yaml | awk '{print $3}')
-DEV_HOST=$(grep "host:" deployment/cicd/kustomize/overlays/dev/ingress-patch.yaml | awk '{print $3}')
-if [ "$BASE_HOST" = "$DEV_HOST" ]; then
-    echo "✅ DEV Ingress Host 정상 ($DEV_HOST)"
-else
-    echo "❌ DEV Ingress Host 오류 (base: $BASE_HOST, dev: $DEV_HOST)"
-fi
-
-# 3. Kustomize 빌드 테스트
-echo "3. Kustomize 빌드 테스트..."
-for env in dev staging prod; do
-    if kubectl kustomize deployment/cicd/kustomize/overlays/$env > /dev/null 2>&1; then
-        echo "✅ $env 환경 빌드 성공"
-    else
-        echo "❌ $env 환경 빌드 실패"
-    fi
-done
-
-# 4. Jenkinsfile JDK 버전 확인
-echo "4. Jenkinsfile JDK 버전 검증..."
-if grep -q "gradle:jdk21" deployment/cicd/Jenkinsfile; then
-    echo "✅ JDK 21 버전 정상"
-else
-    echo "❌ JDK 버전 확인 필요"
-fi
-
-# 5. Secret stringData 사용 확인
-echo "5. Secret stringData 사용 검증..."
-if grep -r "stringData:" deployment/cicd/kustomize/overlays/*/secret-*-patch.yaml > /dev/null; then
-    echo "✅ stringData 사용 정상"
-else
-    echo "❌ stringData 사용 확인 필요"
-fi
-
-echo "🎯 검증 완료!"
-```
-
-### **일반적인 문제 해결**
-1. **이미지 빌드 실패**: Dockerfile 경로 및 JAR 파일 확인
-2. **배포 실패**: 리소스 할당량 및 네임스페이스 확인  
-3. **Quality Gate 실패**: 테스트 커버리지 및 코드 품질 개선
-4. **Kustomize 빌드 실패**: patch 파일의 target 매칭 확인
-
-### **로그 확인 방법**
-```bash
-# Jenkins 빌드 로그 확인 (웹 UI에서)
-# Kubernetes Pod 로그 확인
-kubectl logs -n phonebill-{환경} deployment/{서비스명}
-kubectl describe pod -n phonebill-{환경} -l app={서비스명}
-```
+4. **모니터링 설정**
+   - 배포 상태 모니터링
+   - 알림 시스템 구성

+# Production Overlay Configuration
+
+This directory contains the Kustomize overlay configuration for the production environment of the phonebill project.
+
+## Configuration Overview
+
+### Environment Details
+- **Namespace**: `phonebill-prod`
+- **Environment**: Production
+- **Replicas**: 3 (for all services)
+- **Domain**: `phonebill.yourdomain.com`
+- **Image Tag**: `prod-latest`
+- **SSL**: Enabled with HTTPS redirect
+
+### Security Configuration
+- **JWT Access Token**: 30분 (1800000ms) - 보안 강화를 위한 짧은 만료시간
+- **JWT Refresh Token**: 12시간 (43200000ms)
+- **DDL Auto**: `validate` - 프로덕션 안전성을 위한 스키마 검증 모드
+- **SSL Redirect**: 강제 HTTPS 리디렉션
+
+### Resource Allocation
+All services are configured with:
+- **Requests**: 1024m CPU, 1024Mi Memory
+- **Limits**: 4096m CPU, 4096Mi Memory
+
+### Health Checks
+- **Liveness Probe**: 2분 초기 지연, 30초 간격
+- **Readiness Probe**: 1분 초기 지연, 10초 간격
+

+## Deployment Command
+
+```bash
+# Apply production configuration
+kubectl apply -k deployment/cicd/kustomize/overlays/prod/
+
+# Validate configuration before applying
+kubectl kustomize deployment/cicd/kustomize/overlays/prod/
+```
+
+## Important Notes
+
+1. **Secret Values**: 모든 시크릿 값들은 실제 프로덕션 환경에 맞게 변경해야 합니다.
+2. **Domain Configuration**: `phonebill.yourdomain.com`을 실제 도메인으로 변경하세요.
+3. **Certificate**: SSL 인증서 설정을 위해 cert-manager가 구성되어 있어야 합니다.
+4. **Database**: 각 서비스별 전용 데이터베이스 인스턴스가 필요합니다.
+5. **Monitoring**: 프로덕션 환경에서는 모니터링 및 로깅 설정이 중요합니다.
+
+## Database Services Required
+
+프로덕션 환경에서는 다음 데이터베이스 서비스들이 필요합니다:
+- `auth-postgres-prod-service` (사용자 서비스)
+- `bill-inquiry-postgres-prod-service` (요금조회 서비스)
+- `product-change-postgres-prod-service` (상품변경 서비스)
+- `redis-prod-service` (공통 캐시)
