RUN pip install --user -r requirements.txt # 运行阶段 FROM python:3.9-slim WORKDIR /app COPY --frombuilder /root/.local /root/.local COPY . . ENV PATH/root/.local/bin:$PATH CMD [python, app/main.py]2. 健康检查配置在Kubernetes配置中添加健康检查livenessProbe: httpGet: path: /health port: 8000 initialDelaySeconds: 30 periodSeconds: 10 readinessProbe: httpGet: path: /ready port: 8000 initialDelaySeconds: 5 periodSeconds: 53. 环境变量管理使用ConfigMap和Secret管理配置apiVersion: v1 kind: ConfigMap metadata: name: opendesign-config data: DATABASE_URL: postgresql://user:passdb:5432/opendesign REDIS_URL: redis://redis:6379 监控与日志1. 集中式日志收集配置容器日志输出到标准输出import logging import sys logging.basicConfig( levellogging.INFO, format%(asctime)s - %(name)s - %(levelname)s - %(message)s, handlers[logging.StreamHandler(sys.stdout)] )2. 性能监控集成Prometheus监控指标from prometheus_client import Counter, Histogram REQUEST_COUNT Counter(http_requests_total, Total HTTP requests) REQUEST_LATENCY Histogram(http_request_duration_seconds, HTTP request latency) CI/CD流水线集成1. GitHub Actions自动化部署创建.github/workflows/deploy.ymlname: Deploy to Kubernetes on: push: branches: [ main ] jobs: deploy: runs-on: ubuntu-latest steps: - uses: actions/checkoutv2 - name: Build Docker image run: docker build -t opendesign-backend:${{ github.sha }} . - name: Deploy to Kubernetes run: kubectl set image deployment/opendesign-backend opendesign-backendopendesign-backend:${{ github.sha }}️ 安全最佳实践1. 最小权限原则# 创建非root用户 RUN adduser --disabled-password --gecos appuser USER appuser2. 镜像安全扫描# 使用Trivy扫描镜像漏洞 docker run --rm -v /var/run/docker.sock:/var/run/docker.sock aquasec/trivy image opendesign-backend:latest 弹性伸缩配置1.
