docker - 为什么 IIS 上的 docker 在源代码更改后会出现 http 403 错误？

问题描述

我可以成功构建并运行一个演示经典 asp 站点（此处给出：https ://www.docker.com/blog/get-apps-off-windows-2003-cloud-docker-enterprise/ ）（源代码在这里：https://github.com/sixeyed/presentations/tree/master/docker-webinars/from-w2k3-to-cloud）与以下 Dockerfile：

# escape=`
FROM microsoft/iis:windowsservercore-ltsc2016
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]

RUN Install-WindowsFeature Web-ASP
COPY ./share/ClassicAspApp.zip .

RUN Expand-Archive -Path ClassicAspApp.zip -DestinationPath C:\ClassicAspApp; `
    Remove-Item ClassicAspApp.zip

RUN Remove-Website -Name 'Default Web Site'; `
    New-Website -Name web-app -Port 80 -PhysicalPath C:\ClassicAspApp

构建映像（docker image build -t Sixeyed/w2k3-classic-asp -f .\docker\classic-asp\Dockerfile .）并运行容器（docker container run -d Sixeyed/w2k3-classic-asp）然后浏览到特定的 url（由 docker container inspect 找到）我确实可以让经典的 asp 站点按预期工作。

但是，每当我解压缩并更改（甚至一点）演示 asp 文件（在共享文件夹中）中的源代码，然后重建图像并再次运行容器并浏览到 url 时，我总是会遇到 http 403 - Forbidden : 访问被拒绝。您无权使用您提供的凭据查看此目录或页面。

我试图从许多来源（例如Docker 中的 IIS 返回 403 和IIS 上的 Dockerize ASP Classic）找到解决方案，但到目前为止没有成功。

谁能弄清楚为什么我在源代码中更改测试asp文件时总是遇到http 403？那么，应该怎么做才能解决这个问题呢？

解决方案

I think I found a solution on my own - although I really do not yet know why changing the source code of the demo project actually led to the 403 error. But however in examining the issue I created a new simple classic asp -project in another directory and adapted the Dockerfile to these path changes like so:

# escape=`
FROM microsoft/iis:windowsservercore-ltsc2016
SHELL ["powershell", "-Command"]
RUN Install-WindowsFeature Web-ASP
RUN mkdir C:\testAsp
COPY ./code/asp/ C:\testAsp
RUN Remove-Website -Name 'Default Web Site'; `
    New-Website -Name web-app -Port 8000 -PhysicalPath C:\testAsp

And after that I still received http-403 error. Then I found the following reply: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied and suddenly realized that because my asp-test file is not named as the default.asp -file the server is not finding it. So, my error was due to fairly naive and simple reason - at least in the second demo.

But asp-file in the first demo project was really of default type (default.asp) and therefore I do not for sure figure out why any changes in it will turn it to http-403 error. Maybe it has something to do with unzipping and zipping in between, and the server cannot find the rezipped folder with asp-file in it any more.

However, now at least the basic dockering of classic asp site works!
