RUN npm run build # 生产阶段仅包含运行时必要文件 FROM nginx:alpine COPY --frombuilder /app/dist /usr/share/nginx/html COPY nginx.conf /etc/nginx/nginx.conf EXPOSE 80这种多阶段构建方式显著减少了最终镜像的体积同时提高了安全性因为生产镜像中不包含构建工具和开发依赖。Kubernetes部署架构设计对于生产环境推荐使用Kubernetes进行容器编排。以下是一个完整的部署配置示例apiVersion: apps/v1 kind: Deployment metadata: name: airi-deployment spec: replicas: 3 selector: matchLabels: app: airi template: metadata: labels: app: airi spec: containers: - name: airi-web image: airi-app:latest ports: - containerPort: 80 env: - name: API_KEY valueFrom: secretKeyRef: name: airi-secrets key: api-key - name: MODEL_PROVIDER value: openai resources: requests: memory: 512Mi cpu: 250m limits: memory: 1Gi cpu: 500m livenessProbe: httpGet: path: /health port: 80 initialDelaySeconds: 30 periodSeconds: 10 readinessProbe: httpGet: path: /ready port: 80 initialDelaySeconds: 5 periodSeconds: 5服务网格与服务发现机制在微服务架构中服务发现是确保系统可靠性的关键组件。AIri项目通过Headless Service实现高效的服务发现apiVersion: v1 kind: Service metadata: name: airi-headless spec: clusterIP: None selector: app: airi ports: - port: 80 targetPort: 80结合服务网格技术可以实现更精细的流量管理、安全策略和可观测性。建议使用Istio或Linkerd等服务网格解决方案为AIri的微服务架构提供以下能力流量管理支持金丝雀发布、A/B测试、蓝绿部署安全策略mTLS加密、基于角色的访问控制可观测性分布式追踪、指标收集、日志聚合监控告警体系构建Prometheus监控配置建立全面的监控体系对于保障AIri服务的稳定性至关重要。以下是一个Prometheus ServiceMonitor配置示例apiVersion: monitoring.coreos.com/v1 kind: ServiceMonitor metadata: name: airi-monitor labels: release: prometheus spec: selector: matchLabels: app: airi endpoints: -
