本文主要描述如何让传统ASP.NET网站在Docker中运行，侧重Docker image 搭建。
使用条件：
- Docker for windows 用户切换到Windows 容器模式
- Windows Server 2016 用户 开启 Windows Container
关于Docker for windows，nanoserver,Windows Container一些概念区分
- Docker for windows 在 win10 和 Windows Server 2016 上都能安装，但使用Docker for windows 开启Windows Container本质上都是在Hyper-v上运行。所以效率肯定没有原生的高，同时win10家庭版用户也跑不了Windows Container。
- 在Windows Server 2016上开启的Windows Container 是“原生”的，Windows Container与主机共享内核（博主未验证），用于企业生产环境
- nanoserver是超简版Windows Server 2016,目前微软只允许它作为在容器中运行，由于是超简版，没有IIS，但是可以手工部署，好像也没有framework,自然也跑不了ASP.NET ，但是正是由于它的精简，特别适合作为ASP.NET Core的 windows 生产运行环境！详情 docs.microsoft.com

docker tag microsoft/aspnet:4.7.2-windowsservercore-ltsc2016 microsoft/aspnet:latest有两种方式运行网站
直接使用ASPNET镜像运行网站
docker run `
-d `
--link mssql01 `
--name siteserver01 `
-v C:/Users/Administrator/Desktop/Web/SiteServer01:C:/inetpub/wwwroot `
-p 80:80 `

microsoft/aspnet将网站封装进容器

其中"."代表网站根目录

EXPOSE 80docker build -t yourname/website:version .docker run --link mssql01 -d -p 80:80 --name website01 --restart=always yourname/website:version容器互联(可选 除link的另外一种方式)
