Docker容器化实施方案
基础镜像选择策略
针对微信小程序开发特点，我们选择Node.js官方镜像作为基础：
# 多阶段构建Dockerfile
FROM node:18-alpine AS builder
# 设置工作目录
WORKDIR /app
# 复制package文件
COPY package*.json ./
COPY .npmrc ./
# 安装依赖
RUN npm install --registry=https://registry.npmmirror.com
# 复制源码
COPY . .
# 构建检查（微信小程序无需传统构建）
RUN npm run test || echo "构建检查完成"
# 生产阶段
FROM node:18-alpine AS production
WORKDIR /app
COPY --from=builder /app .
# 设置环境变量
ENV NODE_ENV=production
ENV WECHAT_APP_ID=your_app_id
ENV SUB_DOMAIN=your_sub_domain
# 暴露端口（用于开发工具连接）
EXPOSE 9229
# 启动命令
CMD ["npm", "start"]

安全最佳实践
容器安全加固
# 安全加固的Dockerfile
FROM node:18-alpine AS builder
# 使用非root用户
RUN addgroup -g 1001 -S nodejs
RUN adduser -S nextjs -u 1001
# 设置安全上下文
USER nextjs
WORKDIR /app
COPY --chown=nextjs:nodejs . .
# 安全扫描
RUN npm audit --production

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: wechat-mall-network-policy
namespace: wechat-mall
spec:
podSelector:

port: 9229
egress:
- to:
- namespaceSelector:
matchLabels:

性能优化策略
资源配额管理
# resource-quota.yaml
apiVersion: v1
kind: ResourceQuota
metadata:
name: wechat-mall-quota
namespace: wechat-mall
spec:
hard:
requests.cpu: "2"
requests.memory: 4Gi
limits.cpu: "4"
limits.memory: 8Gi
pods: "10"
services: "5"
缓存策略优化
// 基于Redis的缓存层
const redis = require('redis');
const client = redis.createClient({
host: process.env.REDIS_HOST,
port: process.env.REDIS_PORT
});
const cacheMiddleware = (key, ttl = 300) => {
return async (req, res, next) => {
try {
const cached = await client.get(key);
if (cached) {
return res.json(JSON.parse(cached));
}
res.sendResponse = res.json;
res.json = (body) => {
client.setex(key, ttl, JSON.stringify(body));
res.sendResponse(body);
};
next();
} catch (error) {
next();
}
};
};
故障排除与调试
常见问题解决方案
| 问题现象 | 可能原因 | 解决方案 |
|---|---|---|
| 容器启动失败 | 环境变量缺失 | 检查ConfigMap配置 |
| 构建超时 | 网络问题 | 使用国内镜像源 |
| 内存溢出 | 资源限制过小 | 调整Pod资源限制 |
| 连接超时 | 网络策略限制 | 检查NetworkPolicy |
