name: postgres image: postgres:16 env: - name: POSTGRES_DB value: instatic - name: POSTGRES_USER value: instatic - name: POSTGRES_PASSWORD valueFrom: secretKeyRef: name: instatic-secrets key: postgres-password ports: - containerPort: 5432 volumeMounts: - name: postgres-data mountPath: /var/lib/postgresql/data resources: requests: memory: 256Mi cpu: 250m limits: memory: 512Mi cpu: 500m livenessProbe: exec: command: - pg_isready - -U - instatic initialDelaySeconds: 30 periodSeconds: 10 readinessProbe: exec: command: - pg_isready - -U - instatic initialDelaySeconds: 5 periodSeconds: 5 volumeClaimTemplates: - metadata: name: postgres-data spec: accessModes: [ ReadWriteOnce ] resources: requests: storage: 10Gi步骤3部署Instatic应用现在部署Instatic主应用。注意我们使用了官方镜像并配置了健康检查apiVersion: apps/v1 kind: Deployment metadata: name: instatic-app namespace: instatic spec: replicas: 2 selector: matchLabels: app: instatic template: metadata: labels: app: instatic spec: containers: - name: instatic image: ghcr.io/corebunch/instatic:latest env: - name: DATABASE_URL value: postgres://instatic:$(POSTGRES_PASSWORD)instatic-postgres:5432/instatic - name: INSTATIC_SECRET_KEY valueFrom: secretKeyRef: name: instatic-secrets key: instatic-secret-key envFrom: - configMapRef: name: instatic-config ports: - containerPort: 3001 volumeMounts: - name: uploads mountPath: /app/uploads resources: requests: memory: 512Mi cpu: 500m limits: memory: 1Gi cpu: 1000m livenessProbe: httpGet: path: /health port: 3001 initialDelaySeconds: 30 periodSeconds: 10 readinessProbe: httpGet: path: /health port: 3001 initialDelaySeconds: 5 periodSeconds: 5 volumes: - name: uploads persistentVolumeClaim: claimName: instatic-uploads-pvcInstatic内置的Core Framework设计令牌引擎支持颜色、字体、间距的统一管理步骤4配置持久化存储Instatic需要持久化存储来保存媒体文件和SQLite数据库如果使用SQLite模式。以下是持久化卷声明的配置apiVersion: v1 kind: PersistentVolumeClaim metadata: name: instatic-uploads-pvc namespace: instatic spec: accessModes: - ReadWriteMany resources: requests: storage: 20Gi storageClassName: standard步骤5创建服务和Ingress为了让Instatic对外提供服务我们需要创建Service和Ingress资源apiVersion: v1 kind: Service metadata: name: instatic-service namespace: instatic spec: selector: app: instatic ports: - port: 80 targetPort: 3001 type: ClusterIP --- apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: instatic-ingress namespace: instatic annotations: cert-manager.io/cluster-issuer: letsencrypt-prod nginx.ingress.kubernetes.io/proxy-body-size: 50m spec: ingressClassName: nginx tls: - hosts: - cms.your-domain.com secretName: instatic-tls rules: - host: cms.your-domain.com http: paths: - path: / pathType: Prefix backend: service: name: instatic-service port: number: 80高级配置优化Instatic在Kubernetes中的性能水平扩展策略Instatic的无状态架构使其非常适合水平扩展。您可以轻松增加副本数量apiVersion: autoscaling/v2 kind: HorizontalPodAutoscaler metadata: name: instatic-hpa namespace: instatic spec: scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: instatic-app minReplicas: 2 maxReplicas: 10 metrics: - type: Resource resource: name: cpu target: type: Utilization averageUtilization: 70资源限制优化根据实际使用情况调整资源限制resources: requests: memory: 256Mi cpu: 250m limits: memory: 512Mi cpu: 500m健康检查配置Instatic内置了健康检查端点/health我们已经在Deployment中配置了liveness和readiness探针。这对于Kubernetes的自我修复至关重要。Instatic的可视化组件系统支持参数化设计和插槽填充数据库选择SQLite vs PostgreSQLSQLite模式适合小型站点如果您运行的是小型个人博客或单作者网站SQLite是完美的选择。配置简单无需单独的数据库服务env: - name: DATABASE_URL value: sqlite:/app/data/cms.db volumeMounts: - name: data mountPath: /app/dataPostgreSQL模式适合团队协作对于多作者团队或需要水平扩展的场景PostgreSQL是更好的选择env: - name: DATABASE_URL value: postgres://instatic:$(POSTGRES_PASSWORD)instatic-postgres:5432/instatic密钥管理最佳实践生成加密密钥在部署前使用Instatic提供的工具生成加密密钥bun run scripts/generate-secret-key.tsKubernetes Secret配置将生成的密钥安全地存储在Kubernetes Secret中apiVersion: v1 kind: Secret metadata: name: instatic-secrets namespace: instatic type: Opaque data: instatic-secret-key: base64-encoded-key postgres-password: base64-encoded-password监控和日志管理配置日志收集Instatic使用结构化日志输出便于集成到现有的日志系统中spec: containers: -
