+
+## Kustomize 구조 설명
+
+### Base 구조
+
+Base는 모든 환경에서 공통으로 사용되는 기본 매니페스트입니다.
+
+**주요 리소스:**
+- **ConfigMap (cm-common)**: 환경 변수, 프로파일 설정
+- **Secret (secret-common)**: JWT 시크릿, Redis 패스워드
+- **Ingress**: API 라우팅 규칙
+- **Deployment**: 각 서비스별 배포 설정
+- **Service**: 각 서비스별 ClusterIP 서비스
+- **Secret**: 각 서비스별 데이터베이스 연결 정보
+
+### Overlay 구조
+
+각 환경(dev/staging/prod)별로 Base를 오버라이드합니다.
+
+#### DEV 환경
+- **Replicas**: 1
+- **Resources**: CPU 256m-1024m, Memory 256Mi-1024Mi
+- **Profile**: dev
+- **DDL**: update
+- **Log Level**: DEBUG
+- **Image Tag**: dev-{timestamp}
+
+#### STAGING 환경
+- **Replicas**: 2
+- **Resources**: CPU 512m-2048m, Memory 512Mi-2048Mi
+- **Profile**: staging
+- **DDL**: validate
+- **Log Level**: INFO
+- **Image Tag**: staging-{timestamp}
+- **SSL**: Enabled
+
+#### PROD 환경
+- **Replicas**: 3
+- **Resources**: CPU 1024m-4096m, Memory 1024Mi-4096Mi
+- **Profile**: prod
+- **DDL**: validate
+- **Log Level**: WARN
+- **JWT Expiration**: 짧게 설정 (보안 강화)
+- **Image Tag**: prod-{timestamp}
+- **SSL**: Enabled

+
+## GitHub Actions 워크플로우
+
+### 트리거 조건
+
+1. **Push 이벤트**:
+   - 브랜치: `main`, `develop`
+   - 경로: 서비스 코드 변경 시 (`user/**`, `meeting/**` 등)
+
+2. **Pull Request**:
+   - 대상 브랜치: `main`
+
+3. **수동 실행 (workflow_dispatch)**:
+   - Environment 선택: dev/staging/prod
+   - SonarQube 분석 스킵 선택: true/false
+
+### 워크플로우 단계
+
+#### 1. Build Job
+1. 소스코드 체크아웃
+2. JDK 21 설정
+3. 환경 결정 (input 또는 기본값 dev)
+4. Gradle 빌드 (테스트 제외)
+5. SonarQube 분석 (선택적)
+6. 빌드 아티팩트 업로드
+7. 이미지 태그 생성 (타임스탬프 기반)
+
+#### 2. Release Job
+1. 빌드 아티팩트 다운로드
+2. Docker Buildx 설정
+3. Docker Hub 로그인 (Rate Limit 방지)
+4. ACR 로그인
+5. 각 서비스별 Docker 이미지 빌드 및 푸시
+
+#### 3. Deploy Job
+1. Azure CLI 설치 및 로그인
+2. kubectl 설정
+3. AKS Credentials 가져오기
+4. 네임스페이스 생성
+5. Kustomize 설치
+6. 이미지 태그 업데이트
+7. 매니페스트 적용
+8. Deployment Ready 대기
+
+---
+
+## 배포 방법
+
+### 1. 자동 배포 (Push/PR)
+
+코드를 `main` 또는 `develop` 브랜치에 push하면 자동으로 dev 환경에 배포됩니다.
+
+```bash
+git add .
+git commit -m "feat: 새로운 기능 추가"
+git push origin develop
+```
+
+### 2. 수동 배포 (GitHub Actions UI)
+
+1. GitHub Repository > Actions 탭 이동
+2. "Backend Services CI/CD" 워크플로우 선택
+3. "Run workflow" 버튼 클릭
+4. 환경 선택 (dev/staging/prod)
+5. SonarQube 분석 스킵 여부 선택
+6. "Run workflow" 실행
+
+### 3. 로컬에서 수동 배포
+
+```bash
+# 스크립트 실행 권한 확인
+chmod +x .github/scripts/deploy-actions.sh
+
+# DEV 환경에 배포 (기본)
+./.github/scripts/deploy-actions.sh dev latest
+
+# STAGING 환경에 특정 이미지 태그로 배포
+./.github/scripts/deploy-actions.sh staging 20250127120000
+
+# PROD 환경에 배포
+./.github/scripts/deploy-actions.sh prod 20250127120000
+```
+
+---
+
+## 롤백 방법
+
+### 1. GitHub Actions를 통한 롤백
+
+1. GitHub > Actions > 성공한 이전 워크플로우 선택
+2. "Re-run all jobs" 클릭
+3. 이전 버전으로 재배포됨
+
+### 2. kubectl을 이용한 롤백
+
+```bash
+# 특정 Revision으로 롤백
+kubectl rollout undo deployment/user -n hgzero --to-revision=2
+
+# 이전 버전으로 롤백
+kubectl rollout undo deployment/user -n hgzero
+
+# 롤백 상태 확인
+kubectl rollout status deployment/user -n hgzero
+
+# Rollout 히스토리 확인
+kubectl rollout history deployment/user -n hgzero
+```
+
+### 3. 수동 스크립트를 이용한 롤백
+
+```bash
+# 이전 안정 버전의 이미지 태그로 배포
+./.github/scripts/deploy-actions.sh dev 20250126110000
+```
+
+---
+
+## SonarQube 설정
+
+### 프로젝트 생성
+
+각 서비스별로 SonarQube 프로젝트를 생성하세요:
+- hgzero-user-dev
+- hgzero-meeting-dev
+- hgzero-stt-dev
+- hgzero-ai-dev
+- hgzero-notification-dev
+
+### Quality Gate 설정
+
+기본 Quality Gate 설정:
+- **Coverage**: >= 80%
+- **Duplicated Lines**: <= 3%
+- **Maintainability Rating**: <= A
+- **Reliability Rating**: <= A
+- **Security Rating**: <= A
+
+### Gradle 설정 (이미 구성됨)
+
+```gradle
+// build.gradle
+plugins {
+    id 'org.sonarqube' version '4.0.0.2929'
+    id 'jacoco'
+}
+
+sonarqube {
+    properties {
+        property "sonar.projectKey", "hgzero-${project.name}"
+        property "sonar.projectName", "hgzero-${project.name}"
+    }
+}
+
+jacocoTestReport {
+    reports {
+        xml.enabled true
+    }
+}
+```
+
+---
+
+## 트러블슈팅
+
+### 1. 이미지 Pull 실패
+
+**증상**: `ImagePullBackOff` 또는 `ErrImagePull`
+
+**해결 방법**:
+```bash
+# ACR 로그인 테스트
+az acr login --name acrdigitalgarage02
+
+# Image Pull Secret 재생성
+kubectl delete secret acr-secret -n hgzero
+kubectl create secret docker-registry acr-secret \
+  --docker-server=acrdigitalgarage02.azurecr.io \
+  --docker-username=acrdigitalgarage02 \
+  --docker-password={ACR_PASSWORD} \
+  -n hgzero
+```
+
+### 2. Deployment 타임아웃
+
+**증상**: `deployment "user" exceeded its progress deadline`
+
+**해결 방법**:
+```bash
+# Pod 상태 확인
+kubectl get pods -n hgzero
+
+# Pod 로그 확인
+kubectl logs -n hgzero {pod-name}
+
+# Events 확인
+kubectl describe pod -n hgzero {pod-name}
+```
+
+### 3. Health Check 실패
+
+**증상**: Deployment가 Ready 상태로 전환되지 않음
+
+**해결 방법**:
+```bash
+# Actuator health 엔드포인트 확인
+kubectl exec -n hgzero {pod-name} -- curl http://localhost:8080/actuator/health
+
+# 애플리케이션 로그 확인
+kubectl logs -n hgzero {pod-name} -f
+```
+
+### 4. Kustomize 빌드 오류
+
+**증상**: `kustomize build` 실패
+
+**해결 방법**:
+```bash
+# 로컬에서 Kustomize 검증
+kubectl kustomize .github/kustomize/overlays/dev
+
+# YAML 문법 검증
+yamllint .github/kustomize/overlays/dev/*.yaml
+```
+
+### 5. SonarQube 연결 실패
+
+**증상**: SonarQube Analysis 단계에서 연결 오류
+
+**해결 방법**:
+1. SONAR_HOST_URL이 올바른지 확인
+2. SONAR_TOKEN이 유효한지 확인
+3. SonarQube 서비스 상태 확인:
+   ```bash
+   kubectl get pods -n sonarqube
+   kubectl logs -n sonarqube {sonarqube-pod}
+   ```
+
+### 6. 환경 변수 로드 실패
+
+**증상**: 환경 설정 파일을 찾을 수 없음
+
+**해결 방법**:
+```bash
+# 파일 존재 확인
+ls -la .github/config/
+
+# 파일 내용 확인
+cat .github/config/deploy_env_vars_dev
+```

+# STAGING Environment Kustomize Overlay
+
+## 개요
+STAGING 환경을 위한 Kustomize overlay 설정입니다.
+
+## 환경 설정
+
+### 네임스페이스
+- `hgzero`
+
+### 공통 설정
+- **프로파일**: staging
+- **DDL 모드**: validate
+- **로그 레벨**: INFO
+- **Ingress 호스트**: hgzero-staging-api.example.com
+- **SSL 리다이렉트**: 활성화
+
+### 리소스 설정
+- **Replicas**: 2
+- **Resource Requests**:
+  - CPU: 512m
+  - Memory: 512Mi
+- **Resource Limits**:
+  - CPU: 2048m
+  - Memory: 2048Mi
+
+## 생성된 파일 목록 (총 14개)
+
+### Common Patches (3개)
+1. `cm-common-patch.yaml` - 공통 ConfigMap 패치
+2. `secret-common-patch.yaml` - 공통 Secret 패치 (JWT, Redis)
+3. `ingress-patch.yaml` - Ingress 패치 (호스트, SSL)
+
+### Service-specific Patches (10개)
+각 서비스(user, meeting, stt, ai, notification)별 2개 파일:
+- `deployment-{서비스명}-patch.yaml` - Deployment 리소스 패치
+- `secret-{서비스명}-patch.yaml` - DB 연결 정보 패치
+
+4. `deployment-user-patch.yaml`
+5. `secret-user-patch.yaml`
+6. `deployment-meeting-patch.yaml`
+7. `secret-meeting-patch.yaml`
+8. `deployment-stt-patch.yaml`
+9. `secret-stt-patch.yaml`
+10. `deployment-ai-patch.yaml`
+11. `secret-ai-patch.yaml`
+12. `deployment-notification-patch.yaml`
+13. `secret-notification-patch.yaml`
+
+### Kustomization (1개)
+14. `kustomization.yaml` - Kustomize 설정 파일
+
+## 데이터베이스 설정
+
+각 서비스별 STAGING 환경 DB 정보:
+- **호스트**: {서비스명}-db-staging
+- **포트**: 5432
+- **데이터베이스명**: {서비스명}_db_staging
+- **사용자명**: {서비스명}_service
+- **비밀번호**: stringData로 정의 (실제 환경에서 변경 필요)
+
+## 이미지 태그
+모든 서비스: `staging-latest`
+
+## 사용 방법
+
+### 1. Kustomize 빌드 확인
+```bash
+kubectl kustomize .github/kustomize/overlays/staging
+```
+
+### 2. STAGING 환경 배포
+```bash
+kubectl apply -k .github/kustomize/overlays/staging
+```
+
+### 3. 배포 상태 확인
+```bash
+kubectl get all -n hgzero
+```
+
+### 4. Secret 업데이트 (실제 배포 시)
+```bash
+# Secret 파일들의 stringData를 실제 STAGING 환경 값으로 변경
+vi .github/kustomize/overlays/staging/secret-common-patch.yaml
+vi .github/kustomize/overlays/staging/secret-user-patch.yaml
+# ... (각 서비스별 secret 파일 수정)
+```
+
+## 주의사항
+1. Secret 파일들의 비밀번호는 반드시 실제 환경에 맞게 변경해야 합니다
+2. Ingress 호스트명을 실제 STAGING 도메인으로 변경해야 합니다
+3. DB 호스트명이 실제 STAGING 환경과 일치하는지 확인해야 합니다
+4. 리소스 제한은 실제 부하 테스트 결과에 따라 조정이 필요할 수 있습니다
+
+## 다음 단계
+- PROD 환경 overlay 생성
+- CI/CD 파이프라인과 통합
+- Monitoring 및 Logging 설정 추가
