Docker镜像构建最佳实践

多阶段构建策略

为了优化镜像体积和安全性,我们采用多阶段构建策略:

# 第一阶段:构建阶段
FROM node:18-alpine AS builder

# 设置工作目录
WORKDIR /app

# 复制package文件
COPY package.json pnpm-lock.yaml ./

# 安装pnpm
RUN npm install -g pnpm@8

# 安装依赖
RUN pnpm install --frozen-lockfile

# 复制源代码
COPY . .

# 构建项目
RUN pnpm run build

# 第二阶段:生产阶段
FROM nginx:alpine AS production

# 复制构建产物
COPY --from=builder /app/dist /usr/share/nginx/html

# 复制nginx配置
COPY nginx.conf /etc/nginx/conf.d/default.conf

# 暴露端口
EXPOSE 80

# 启动nginx
CMD ["nginx", "-g", "daemon off;"]

优化构建配置

在vite.config.ts中,我们已经配置了优化的构建选项:

// vite.config.ts 构建配置
build: {
  chunkSizeWarningLimit: 2000,
  outDir: 'dist',
  minify: 'terser',
  terserOptions: {
    compress: {
      keep_infinity: true,
      drop_console: true,
      drop_debugger: true,
    },
    format: {
      comments: false,
    },
  },
  rollupOptions: {
    output: {
      chunkFileNames: 'static/js/[name]-[hash].js',
      entryFileNames: 'static/js/[name]-[hash].js',
      assetFileNames: 'static/[ext]/[name]-[hash].[ext]',
    },
  },
}

Nginx配置优化

创建优化的nginx配置文件:

# nginx.conf
server {
    listen 80;
    server_name localhost;
    
    # 根目录配置
    root /usr/share/nginx/html;
    index index.html;
    
    # Gzip压缩
    gzip on;
    gzip_vary on;
    gzip_min_length 1024;
    gzip_types text/plain text/css text/xml text/javascript application/javascript application/xml+rss application/json;
    
    # 静态资源缓存
    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff2)$ {
        expires 1y;
        add_header Cache-Control "public, immutable";
    }
    
    # HTML文件不缓存
    location ~* \.(html)$ {
        expires -1;
        add_header Cache-Control "no-store";
    }
    
    # SPA路由支持
    location / {
        try_files $uri $uri/ /index.html;
    }
    
    # 健康检查端点
    location /health {
        access_log off;
        return 200 "healthy\n";
        add_header Content-Type text/plain;
    }
}

性能优化建议

构建优化

# 使用多阶段构建减少镜像体积
# 使用.alpine基础镜像
# 清理构建缓存和临时文件

# 在Dockerfile中添加清理步骤
RUN rm -rf /var/cache/apk/* && \
    rm -rf /tmp/* && \
    rm -rf /root/.npm && \
    rm -rf /root/.cache

运行时优化

# 启用Brotli压缩
brotli on;
brotli_types text/plain text/css application/javascript application/json image/svg+xml;

# 配置缓存策略
location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
    expires 1y;
    add_header Cache-Control "public, immutable";
}
