4.2 Git Repository 생성

# GitHub에서 새 Repository 생성# Repository 이름: runna-k8s-manifests# 로컬에서 초기화mkdir runna-k8s-manifests
cd runna-k8s-manifests
git init
git remote add origin <https://github.com/><your-org>/runna-k8s-manifests.git

# 기본 구조 생성mkdir -p charts/{backend-api,function-executor,redis}/{templates}
mkdir -p argocd/{applications,projects}
mkdir -p monitoring

# README 작성cat > README.md << 'EOF'
# Runna Kubernetes Manifests

Helm Charts and ArgoCD configurations for Runna platform.

## Structure
- `charts/`: Helm charts for applications
- `argocd/`: ArgoCD application definitions
- `monitoring/`: Monitoring stack configurations
EOF

git add .
git commit -m "Initial commit: repository structure"
git push -u origin main

🔄 6단계: ArgoCD 설치 및 설정

6.1 ArgoCD 설치

6.2 ArgoCD 초기 비밀번호 확인

# 초기 admin 비밀번호 확인
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d
echo

# 포트 포워딩 (로컬에서 접속)
kubectl port-forward svc/argocd-server -n argocd 8080:443

# 브라우저에서 <https://localhost:8080> 접속# Username: admin# Password: <위에서 확인한 비밀번호>

6.3 ArgoCD Application 생성

# argocd/applications/backend-api.yamlcat > argocd/applications/backend-api.yaml << 'EOF'
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: backend-api
  namespace: argocd

      selfHeal: true
    syncOptions:
    - CreateNamespace=true
EOF

# ArgoCD에 Application 등록
kubectl apply -f argocd/applications/backend-api.yaml

📊 7단계: Monitoring Stack 설치

7.1 Prometheus 설치

# Prometheus values 파일 생성cat > monitoring/prometheus-values.yaml << 'EOF'
server:
  nodeSelector:
    workload: ops
  persistentVolume:
    enabled: true
    size: 20Gi

alertmanager:
  nodeSelector:
    workload: ops
  persistentVolume:
    enabled: true
    size: 5Gi
EOF

# Prometheus 설치
helm install prometheus prometheus-community/prometheus \
  -n monitoring \
  --create-namespace \
  -f monitoring/prometheus-values.yaml

7.2 Grafana 설치
