🚀 前言：为什么需要容器化部署？

在企业级应用开发中，部署环节往往是开发流程中最容易出错的环节。你是否遇到过以下痛点：

环境不一致：开发环境、测试环境、生产环境配置差异导致的各种诡异问题
依赖冲突：不同服务依赖的运行时版本冲突，难以统一管理
扩展困难：手动部署难以应对流量突增，扩展性差
运维复杂：多服务协调部署、服务发现、负载均衡配置繁琐

Geex框架通过Docker容器化和Kubernetes编排，为企业级应用提供了开箱即用的生产环境部署解决方案。本文将详细介绍如何将Geex应用从开发环境平滑迁移到生产环境。

📦 Geex容器化架构概览

Geex采用微服务架构设计，天然支持容器化部署。典型的Geex生产环境包含以下核心组件：

开发环境配置

# 安装Docker
curl -fsSL https://get.docker.com | sh

# 安装kubectl
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

# 安装Helm
curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

🐳 Docker容器化实战

1. 创建Dockerfile

Geex应用的标准Dockerfile配置：

# 使用官方.NET运行时镜像
FROM mcr.dockerproxy.com/dotnet/aspnet:9.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

# 构建阶段
FROM mcr.dockerproxy.com/dotnet/sdk:9.0 AS build
WORKDIR /src

# 复制项目文件
COPY ["Geex.YourApp/Geex.YourApp.csproj", "Geex.YourApp/"]
COPY ["Geex.YourApp.Module1/Geex.YourApp.Module1.csproj", "Geex.YourApp.Module1/"]
COPY ["Geex.YourApp.Module2/Geex.YourApp.Module2.csproj", "Geex.YourApp.Module2/"]

# 恢复NuGet包
RUN dotnet restore "Geex.YourApp/Geex.YourApp.csproj"

# 复制所有源代码
COPY . .

# 构建应用
WORKDIR "/src/Geex.YourApp"
RUN dotnet build "Geex.YourApp.csproj" -c Release -o /app/build

# 发布阶段
FROM build AS publish
RUN dotnet publish "Geex.YourApp.csproj" -c Release -o /app/publish

# 最终运行时镜像
FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .

# 设置健康检查
HEALTHCHECK --interval=30s --timeout=3s --start-period=30s --retries=3 \
    CMD curl -f http://localhost/health || exit 1

ENTRYPOINT ["dotnet", "Geex.YourApp.dll"]

2. Docker Compose开发环境

version: '3.8'

services:
  geex-app:
    build: .
    ports:
      - "5000:80"
      - "5001:443"
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ConnectionStrings__MongoDB=mongodb://mongodb:27017
      - ConnectionStrings__Redis=redis:6379
    depends_on:
      - mongodb
      - redis
    volumes:
      - ./appsettings.Development.json:/app/appsettings.Development.json:ro

  mongodb:
    image: mongo:6.0
    ports:
      - "27017:27017"
    volumes:
      - mongodb_data:/data/db
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_ROOT_PASSWORD=password

  redis:
    image: redis:7-alpine
    ports:
      - "6379:6379"
    volumes:
      - redis_data:/data

  traefik:
    image: traefik:v2.9
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./traefik.toml:/etc/traefik/traefik.toml:ro

volumes:
  mongodb_data:
  redis_data:

3. 多阶段构建优化

为了优化镜像大小和安全性，推荐使用多阶段构建：

# 第一阶段：构建
FROM mcr.dockerproxy.com/dotnet/sdk:9.0 AS build
WORKDIR /src
COPY . .
RUN dotnet publish -c Release -o /app/publish

# 第二阶段：运行时（使用更小的基础镜像）
FROM mcr.dockerproxy.com/dotnet/aspnet:9.0-alpine AS runtime
WORKDIR /app
COPY --from=build /app/publish .

# 添加非root用户运行
RUN adduser -u 1000 -D appuser && chown -R appuser:appuser /app
USER appuser

ENTRYPOINT ["dotnet", "Geex.YourApp.dll"]

      metrics_path: '/metrics'

应用性能监控仪表板

监控指标	告警阈值	处理建议
CPU使用率	>80%持续5分钟	水平扩展Pod或优化代码
内存使用率	>85%持续5分钟	增加内存限制或优化内存使用
请求延迟	P95 > 500ms	检查数据库查询或优化业务逻辑
错误率	>5%持续2分钟	检查应用日志和依赖服务状态

🛡️ 安全最佳实践

1. 网络安全策略

# network-policy.yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: geex-app-network-policy
  namespace: geex-production
spec:
  podSelector:
    matchLabels:
      app: geex-app
  policyTypes:
  - Ingress
  - Egress
  ingress:
  - from:
    - namespaceSelector:
        matchLabels:
          name: monitoring
    ports:
    - protocol: TCP
      port: 80
  egress:
  - to:
    - podSelector:
        matchLabels:
          app: mongodb
    ports:
    - protocol: TCP
      port: 27017

2. 安全上下文配置

# 在Deployment的spec.template.spec中添加
securityContext:
  runAsNonRoot: true
  runAsUser: 1000
  runAsGroup: 1000
  fsGroup: 1000
  seccompProfile:
    type: RuntimeDefault

🚨 故障排除与调试

常见问题排查表

问题现象	可能原因	解决方案
Pod启动失败	镜像拉取失败	检查镜像仓库权限和网络连通性
健康检查失败	应用启动慢	调整initialDelaySeconds
数据库连接失败	网络策略限制	检查NetworkPolicy配置
内存溢出	内存限制过低	调整resources.limits.memory

调试命令速查

# 查看Pod状态
kubectl get pods -n geex-production

# 查看Pod日志
kubectl logs -f deployment/geex-app -n geex-production

# 进入Pod调试
kubectl exec -it deployment/geex-app -n geex-production -- /bin/sh

# 查看服务发现
kubectl get endpoints -n geex-production

# 查看资源使用情况
kubectl top pods -n geex-production

📈 性能优化建议

1. 资源配额管理

# resource-quota.yaml
apiVersion: v1
kind: ResourceQuota
metadata:
  name: geex-resource-quota
  namespace: geex-production
spec:
  hard:
    requests.cpu: "4"
    requests.memory: 8Gi
    limits.cpu: "8"
    limits.memory: 16Gi
    pods: "10"

2. HPA自动扩缩容

# hpa.yaml
apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: geex-app-hpa
  namespace: geex-production
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: geex-app
  minReplicas: 2
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 70
  - type: Resource
    resource:
      name: memory
      target:
        type: Utilization
        averageUtilization: 80
