+## 사전 요구사항
+
+### 1. 쿠버네티스 클러스터
+
+```bash
+# 서버 정보
+IP: 112.168.212.142
+SSH: ssh -p 22 wace@112.168.212.142
+K8s 버전: v1.28.15
+```
+
+### 2. Harbor 레지스트리 접근 권한
+
+Harbor에 `vexplor` 프로젝트가 생성되어 있어야 합니다.
+
+### 3. Gitea Repository Secrets
+
+Gitea 저장소에 다음 Secrets를 설정해야 합니다:
+
+| Secret 이름 | 설명 |
+|------------|------|
+| `HARBOR_USERNAME` | Harbor 사용자명 |
+| `HARBOR_PASSWORD` | Harbor 비밀번호 |
+| `KUBECONFIG` | base64 인코딩된 Kubernetes config |
+
+---
+
+## 초기 설정
+
+### 1단계: 쿠버네티스 클러스터 접속
+
+```bash
+ssh -p 22 wace@112.168.212.142
+```
+
+### 2단계: Nginx Ingress Controller 설치
+
+```bash
+# Nginx Ingress Controller 설치 (baremetal용)
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.9.5/deploy/static/provider/baremetal/deploy.yaml
+
+# 설치 확인
+kubectl get pods -n ingress-nginx
+kubectl get svc -n ingress-nginx
+```
+
+### 3단계: Local Path Provisioner 설치 (PVC용)
+
+```bash
+# Local Path Provisioner 설치
+kubectl apply -f k8s/local-path-provisioner.yaml
+
+# 설치 확인
+kubectl get pods -n local-path-storage
+kubectl get storageclass
+```
+
+### 4단계: Cert-Manager 설치 (SSL 인증서용)
+
+```bash
+# Cert-Manager 설치
+kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.3/cert-manager.yaml
+
+# 설치 확인
+kubectl get pods -n cert-manager
+
+# ClusterIssuer 생성 (Let's Encrypt)
+cat <<EOF | kubectl apply -f -
+apiVersion: cert-manager.io/v1
+kind: ClusterIssuer
+metadata:
+  name: letsencrypt-prod

+### 5단계: vexplor Secret 생성
+
+```bash
+# Secret 템플릿을 복사하여 실제 값으로 수정
+cp k8s/vexplor-secret.yaml.template k8s/vexplor-secret.yaml
+
+# 값 수정 후 적용
+kubectl apply -f k8s/vexplor-secret.yaml
+```
+
+### 6단계: Gitea Secrets 설정
+
+1. Gitea 저장소로 이동: https://g.wace.me/chpark/vexplor
+2. Settings > Secrets > Actions 메뉴로 이동
+3. 다음 Secrets 추가:
+
+#### HARBOR_USERNAME
+Harbor 로그인 사용자명
+
+#### HARBOR_PASSWORD
+Harbor 로그인 비밀번호
+
+#### KUBECONFIG
+```bash
+# 쿠버네티스 서버에서 실행
+cat ~/.kube/config | base64 -w 0
+```
+출력된 값을 KUBECONFIG secret으로 등록

+# 쿠버네티스 클러스터 구축 가이드
+
+## 📋 개요
+
+이 문서는 Digital Twin 프로젝트의 쿠버네티스 클러스터 구축 과정을 정리한 가이드입니다.
+
+**작성일**: 2024년 12월 22일
+
+---
+
+## 🖥️ 서버 정보
+
+### 기존 서버 (참조용)
+
+| 항목 | 값 |
+|------|-----|
+| IP | 211.115.91.170 |
+| SSH 포트 | 12991 |
+| 사용자 | geonhee |
+| OS | Ubuntu 24.04.3 LTS |
+| K8s 버전 | v1.28.0 |
+| 컨테이너 런타임 | containerd 1.7.28 |
+
+### 새 서버 (구축 완료)
+
+| 항목 | 값 |
+|------|-----|
+| IP | 112.168.212.142 |
+| SSH 포트 | 22 |
+| 사용자 | wace |
+| 호스트명 | waceserver |
+| OS | Ubuntu 24.04.3 LTS |
+| K8s 버전 | v1.28.15 |
+| 컨테이너 런타임 | containerd 1.7.28 |
+| 내부 IP | 10.10.0.74 |
+| CPU | 20코어 |
+| 메모리 | 31GB |
+
+---
+
+## 🔐 SSH 접속 설정
+
+### SSH 키 기반 인증 설정
+
+```bash
+# 1. 로컬에서 SSH 키 확인
+ls -la ~/.ssh/
+
+# 2. 공개키를 서버에 복사
+ssh-copy-id -p 12991 geonhee@211.115.91.170  # 기존 서버
+ssh-copy-id -p 22 wace@112.168.212.142        # 새 서버
+
+# 3. 비밀번호 없이 접속 테스트
+ssh -p 12991 geonhee@211.115.91.170
+ssh -p 22 wace@112.168.212.142
+```
+
+### SSH Config 설정 (선택사항)
+
+```bash
+# ~/.ssh/config 파일에 추가
+Host wace-old
+    HostName 211.115.91.170
+    Port 12991
+    User geonhee
+
+Host wace-new
+    HostName 112.168.212.142
+    Port 22
+    User wace
+```
+
+---
+
+## 🚀 쿠버네티스 클러스터 구축 과정
+
+### 1단계: Swap 비활성화
+
+쿠버네티스는 swap이 활성화되어 있으면 제대로 동작하지 않습니다.
+
+```bash
+# swap 비활성화
+sudo swapoff -a
+
+# 영구적으로 비활성화 (재부팅 후에도 유지)
+sudo sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
+
+# 확인 (아무것도 출력되지 않으면 성공)
+swapon --show
+```
+
+### 2단계: containerd 설정
+
+```bash
+# containerd 기본 설정 생성
+sudo containerd config default | sudo tee /etc/containerd/config.toml
+
+# SystemdCgroup 활성화 (중요!)
+sudo sed -i 's/SystemdCgroup = false/SystemdCgroup = true/g' /etc/containerd/config.toml
+
+# containerd 재시작
+sudo systemctl restart containerd
+
+# 상태 확인
+sudo systemctl is-active containerd
+```
+
+### 3단계: kubeadm init (클러스터 초기화)
+
+```bash
+sudo kubeadm init --pod-network-cidr=10.244.0.0/16
+```
+
+**출력 결과 (중요 정보)**:
+- 클러스터 초기화 성공
+- API 서버: https://10.10.0.74:6443
+- 워커 노드 조인 토큰 생성됨
+
+### 4단계: kubectl 설정
+
+일반 사용자가 kubectl을 사용할 수 있도록 설정합니다.
+
+```bash
+mkdir -p $HOME/.kube
+sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
+sudo chown $(id -u):$(id -g) $HOME/.kube/config
+
+# 확인
+kubectl cluster-info
+```
+
+### 5단계: 네트워크 플러그인 설치 (Flannel)
+
+Pod 간 통신을 위한 네트워크 플러그인을 설치합니다.
+
+```bash
+kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
+```
+
+### 6단계: 단일 노드 설정
+
+마스터 노드에서도 워크로드를 실행할 수 있도록 taint를 제거합니다.
+
+```bash
+kubectl taint nodes --all node-role.kubernetes.io/control-plane-
+```
+
+---
+
+## ✅ 구축 결과
+
+### 클러스터 상태
+
+```bash
+kubectl get nodes -o wide
+```
+
+| NAME | STATUS | ROLES | VERSION | INTERNAL-IP | OS-IMAGE | CONTAINER-RUNTIME |
+|------|--------|-------|---------|-------------|----------|-------------------|
+| waceserver | Ready | control-plane | v1.28.15 | 10.10.0.74 | Ubuntu 24.04.3 LTS | containerd://1.7.28 |
+
+### 시스템 Pod 상태
+
+```bash
+kubectl get pods -n kube-system
+kubectl get pods -n kube-flannel
+```
+
+| 컴포넌트 | 상태 |
+|---------|------|
+| etcd | ✅ Running |
+| kube-apiserver | ✅ Running |
+| kube-controller-manager | ✅ Running |
+| kube-scheduler | ✅ Running |
+| kube-proxy | ✅ Running |
+| coredns (x2) | ✅ Running |
+| kube-flannel | ✅ Running |
+
+---
+
+## 📌 워커 노드 추가 (필요 시)
+
+다른 서버를 워커 노드로 추가하려면:
+
+```bash
+kubeadm join 10.10.0.74:6443 --token 4lfga6.luad9f367uxh0rlq \
+    --discovery-token-ca-cert-hash sha256:9bea59b6fd34115c3f893a4b10bacc0a5409192b288564dc055251210081c86e
+```
+
+**토큰 만료 시 새 토큰 생성**:
+```bash
+kubeadm token create --print-join-command
+```
+
+---
+
+## 🔧 유용한 명령어
+
+### 클러스터 정보 확인
+
+```bash
+# 노드 상태
+kubectl get nodes -o wide
+
+# 모든 Pod 상태
+kubectl get pods -A
+
+# 클러스터 정보
+kubectl cluster-info
+
+# 컴포넌트 상태
+kubectl get componentstatuses
+```
+
+### 문제 해결
+
+```bash
+# kubelet 로그 확인
+sudo journalctl -u kubelet -f
+
+# containerd 로그 확인
+sudo journalctl -u containerd -f
+
+# Pod 상세 정보
+kubectl describe pod <pod-name> -n <namespace>
+
+# Pod 로그 확인
+kubectl logs <pod-name> -n <namespace>
+```
+
+### 클러스터 리셋 (초기화 실패 시)
+
+```bash
+sudo kubeadm reset
+sudo rm -rf /etc/cni/net.d
+sudo rm -rf $HOME/.kube
+sudo iptables -F && sudo iptables -t nat -F && sudo iptables -t mangle -F && sudo iptables -X
+```
+
+---
+
+## 📂 다음 단계: 자동 배포 설정
+
+쿠버네티스 클러스터 구축이 완료되었습니다. 다음 단계로 진행할 사항:
+
+1. **Ingress Controller 설치** (외부 트래픽 라우팅) ✅ 완료
+2. **Cert-Manager 설치** (SSL 인증서 자동 관리)
+3. **Harbor/Registry 연동** (컨테이너 이미지 저장소)
+4. **CI/CD 파이프라인 구성** (Gitea Actions) ✅ 완료
+5. **Helm 설치** (패키지 관리)
+6. **애플리케이션 배포** (Deployment, Service, Ingress) ✅ 완료
+
+### Gitea Actions 자동 배포 설정 완료
+
