无法运行docker IIS windows容器

Question

我是 Docker 新手，并尝试在 Windows 容器内运行旧版 .NET 应用程序（使用 docker 桌面）。这是我的 dockerfile

FROM mcr.microsoft.com/windows/servercore:ltsc2019

SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop';"]

RUN dism.exe /online /enable-feature /all /featurename:iis-webserver /NoRestart

#Configure IIS

RUN Import-Module WebAdministration;New-Item –Path IIS:\AppPools\CustomApppool
RUN C:\windows\system32\inetsrv\appcmd.exe set apppool /apppool.name:CustomApppool /processModel.identityType:SpecificUser /processModel.username:us\user1 /processModel.password:P@@Ss

#Copy website files from App host folder to container wwwroot folder

# Enable Windows authentication
RUN Set-WebConfigurationProperty -Filter '/system.webServer/security/authentication/windowsAuthentication' -Location 'Default Web Site' -Name Enabled -Value False;

RUN Restart-Service W3SVC

EXPOSE 80
ENTRYPOINT ['C:\ServiceMonitor.exe','w3svc']

我可以通过运行来构建图像

docker build -t demo/site

我正在运行此命令来启动容器

docker run -p 8000:80 demo/site:latest

但我收到此错误：

At line:1 char:35
+ $ErrorActionPreference = 'Stop'; ['C:\ServiceMonitor.exe','w3svc']
+                                   ~
Missing type name after '['.

    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordEx

请问我错过了什么？我需要做什么才能启动容器并能够在本地主机上浏览我的网站？

Answer 1

将最后一行的单引号替换为双引号。 也可以尝试用 CMD 替换 ENTRYPOINT。

Answer 2

Windows 容器上的 Docker 文件对转义字符串的方式很挑剔。

您看到的问题显然是覆盖的 SHELL 和 ENTRYPOINT 的组合。

尝试使用 CMD 而不是 ENTRYPOINT：

CMD ["C:\ServiceMonitor.exe","w3svc"]

此外，在设置之后和入口点之前恢复您的 SHELL：

SHELL ["cmd.exe"]
CMD ["C:\ServiceMonitor.exe","w3svc"]

您可以在此处找到适用于 IIS 的 dockerfile 示例：

这个位于另一个图像之上，该图像实际上处理入口点/shell/cmd 配置：

https://github.com/david-garcia-garcia/windowscontainers/blob/master/servercore2022/dockerfile

我建议不要使用服务监视器，你最好使用无限循环的 powershell 入口点，并进行适当的运行状况检查（如果这是 K8S/AKS）。

# escape=`
FROM mcr.microsoft.com/windows/servercore:ltsc2022

SHELL ["powershell.exe"]

##### YOUR SETUP SCRIPT

CMD ["powershell.exe", "-File", "C:\\entrypoint\\entrypoint.ps1" ]
