部署

1. 使用go

# jsoniter: 外部引用的json序列化方式
# nomsgpack: 禁用Gin的默认渲染
go build -tags=jsoniter,nomsgpack -o web-server .

2. 使用docker
   1. 编译名为web-server的镜像

      docker build . -t web-server

   2. 无参数运行：只输出帮助信息

      docker run web-server
      # Output:
      # Usage of ./web-server:
      # ... ...

   3. 启动服务：通过附加应用参数

      docker run -p 8000:8000 web-server -appMode=dev
