+## ⚙️ GitHub Repository 설정
+
+### 1. Repository Secrets 설정
+
+Repository Settings > Secrets and variables > Actions > Repository secrets에 다음을 등록:
+
+```yaml
+# Azure Service Principal
+AZURE_CREDENTIALS:
+{
+  "clientId": "{클라이언트ID}",
+  "clientSecret": "{클라이언트시크릿}",
+  "subscriptionId": "{구독ID}",
+  "tenantId": "{테넌트ID}"
+}
+
+# ACR Credentials
+ACR_USERNAME: acrdigitalgarage01
+ACR_PASSWORD: {ACR패스워드}
+
+# Docker Hub (Rate Limit 해결용)
+DOCKERHUB_USERNAME: {Docker Hub 사용자명}
+DOCKERHUB_PASSWORD: {Docker Hub 패스워드}
+
+# SonarQube (선택사항)
+SONAR_TOKEN: {SonarQube토큰}
+SONAR_HOST_URL: {SonarQube서버URL}
+```
+
+### 2. Repository Variables 설정
+
+Repository Settings > Secrets and variables > Actions > Variables > Repository variables에 등록:
+
+```yaml
+ENVIRONMENT: dev  # 기본값
+SKIP_SONARQUBE: true  # 기본값
+```
+
+### 3. ACR 패스워드 확인 방법
+
+```bash
+az acr credential show --name acrdigitalgarage01
+```
+
+## 🚀 CI/CD 파이프라인 구성
+
+### 워크플로우 트리거
+
+1. **자동 실행**:
+   - `main`, `develop` 브랜치에 Push
+   - `main` 브랜치로 Pull Request
+
+2. **수동 실행**:
+   - Actions 탭 > "Backend Services CI/CD" > "Run workflow"
+   - 환경 선택: dev/staging/prod
+   - SonarQube 분석 여부 선택
+
+### 파이프라인 단계
+
+#### 1. Build and Test
+- Gradle 빌드 (테스트 제외)
+- SonarQube 분석 (선택적)
+- 빌드 아티팩트 업로드
+
+#### 2. Build and Push Docker Images
+- Docker 이미지 빌드
+- ACR에 푸시 (태그: {environment}-{timestamp})
+
+#### 3. Deploy to Kubernetes
+- Kustomize를 이용한 환경별 배포
+- 배포 상태 확인
+- Health Check
+
+## 🔧 환경별 설정
+
+### 개발 환경 (dev)
+- **네임스페이스**: phonebill-dev
+- **Replicas**: 1
+- **Resources**: 256Mi/256m → 1024Mi/1024m
+- **DDL**: update
+- **Host**: phonebill-api.20.214.196.128.nip.io
+- **SSL**: false
+
+### 스테이징 환경 (staging)
+- **네임스페이스**: phonebill-staging
+- **Replicas**: 2
+- **Resources**: 512Mi/512m → 2048Mi/2048m
+- **DDL**: validate
+- **Host**: staging.phonebill.com
+- **SSL**: true (Let's Encrypt)
+
+### 운영 환경 (prod)
+- **네임스페이스**: phonebill-prod
+- **Replicas**: 3
+- **Resources**: 1024Mi/1024m → 4096Mi/4096m
+- **DDL**: validate
+- **JWT Token**: 1시간 (보안 강화)
+- **Host**: phonebill.com
+- **SSL**: true (Let's Encrypt)
+
+## 📝 수동 배포 방법
+
+### 스크립트 사용
+```bash
+# 개발 환경 배포
+./.github/scripts/deploy-actions.sh dev latest
+
+# 스테이징 환경 배포
+./.github/scripts/deploy-actions.sh staging 20241215123456
+
+# 운영 환경 배포
+./.github/scripts/deploy-actions.sh prod 20241215123456
+```
+
+### kubectl 직접 사용
+```bash
+# 환경별 디렉토리로 이동
+cd .github/kustomize/overlays/dev
+
+# 이미지 태그 업데이트
+kustomize edit set image acrdigitalgarage01.azurecr.io/phonebill/api-gateway:dev-20241215123456
+
+# 배포 실행
+kubectl apply -k .
+```
+
+## 🔄 롤백 방법
+
+### 1. GitHub Actions를 통한 롤백
+1. GitHub > Actions > 성공한 이전 워크플로우 선택
+2. "Re-run all jobs" 클릭
+
+### 2. kubectl을 이용한 롤백
+```bash
+# 특정 버전으로 롤백
+kubectl rollout undo deployment/api-gateway -n phonebill-dev --to-revision=2
+
+# 롤백 상태 확인
+kubectl rollout status deployment/api-gateway -n phonebill-dev
+```
+
+### 3. 수동 스크립트를 이용한 롤백
+```bash
+# 이전 안정 버전 이미지 태그로 배포
+./.github/scripts/deploy-actions.sh dev 20241214123456
+```
+
+## 🔍 SonarQube 설정
+
+### Quality Gate 기준
+- Coverage: >= 80%
+- Duplicated Lines: <= 3%
+- Maintainability Rating: <= A
+- Reliability Rating: <= A
+- Security Rating: <= A
+
+### 프로젝트 생성
+각 서비스별로 `phonebill-{service}-{environment}` 형식으로 프로젝트 생성
+
+## 📊 모니터링 및 확인
+
+### 배포 상태 확인
+```bash
+# Pod 상태 확인
+kubectl get pods -n phonebill-dev
+
+# 서비스 상태 확인
+kubectl get services -n phonebill-dev
+
+# Ingress 확인
+kubectl get ingress -n phonebill-dev
+
+# 로그 확인
+kubectl logs -f deployment/api-gateway -n phonebill-dev
+```
+
+### Health Check
+```bash
+# API Gateway Health Check
+kubectl -n phonebill-dev exec deployment/api-gateway -- curl -f http://localhost:8080/actuator/health
+```
+
+## ⚠️ 주의사항
+
+1. **환경별 Secret 관리**:
+   - 현재는 동일한 값으로 설정되어 있음
+   - 실제 운영 시 환경별로 다른 값 설정 필요
+
+2. **도메인 설정**:
+   - staging/prod 환경의 도메인은 실제 구매한 도메인으로 변경 필요
+   - SSL 인증서는 cert-manager 설정 필요
+
+3. **리소스 한계**:
+   - 환경별 리소스 설정은 실제 부하에 맞게 조정 필요
+
+4. **데이터베이스 연결**:
+   - 환경별로 다른 데이터베이스 인스턴스 사용 권장
+
+## 🔧 문제 해결
+
+### 일반적인 문제들
+
+1. **이미지 Pull 실패**:
+   ```bash
+   # Secret 확인
+   kubectl get secret secret-imagepull -n phonebill-dev -o yaml
+   ```
+
+2. **ConfigMap/Secret 업데이트 반영 안됨**:
+   ```bash
+   # Pod 재시작
+   kubectl rollout restart deployment/api-gateway -n phonebill-dev
+   ```
+
+3. **Ingress IP 할당 안됨**:
+   ```bash
+   # Ingress Controller 상태 확인
+   kubectl get pods -n ingress-nginx
+   ```
