无法构建 ASP.Net 容器

Question

Windows 10 version 1607
Docker for Windows: Version 17.06.1-ce-win24 (13025)

我正在尝试使用 the provided docs 构建一个 asp .net 4.6 容器，但它不起作用。

我正在使用this provided dockerfile。我将它复制到我的一个 asp .net 解决方案的根目录中。

我运行了这个命令：

$ docker build -t aspnet-site --build-arg site_root=/

这是输出

PS> docker build -t aspnet-site . --build-arg 'site_root=/'

所以它确实在文档中这么说（所以我尝试注释掉 servicemonitor 的东西并且它起作用了）：

无需在 Dockerfile 中指定 ENTRYPOINT，因为 microsoft/aspnet 基础映像已经包含一个入口点应用程序 监视 IIS 万维网发布服务的状态 (W3SVC)。

改用这个 dockerfile 试试。它将使用 aspnet 图像：

FROM microsoft/aspnet
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop';"]

EXPOSE 80

RUN Remove-WebSite -Name 'Default Web Site'  
RUN New-Website -Name 'YourSiteName' -Port 80 -PhysicalPath 'C:\YourFolderName' -ApplicationPool '.NET v4.5'

ADD "LocalFolderPath" /YourFolderName
