SPA docker windows容器的Azure管道构建失败

Question

我正在将Asp.net核心与angular和docker windows容器一起使用。这是dockerfile，如下所示：

Dockerfile：

#escape=`
FROM mcr.microsoft.com/powershell:nanoserver-1809 AS downloadnodejs
SHELL ["pwsh", "-Command", "$ErrorActionPreference = 'Stop';$ProgressPreference='silentlyContinue';"]
RUN Invoke-WebRequest -OutFile nodejs.zip -UseBasicParsing "https://nodejs.org/dist/v10.16.3/node-v10.16.3-win-x64.zip"; `
Expand-Archive nodejs.zip -DestinationPath C:\; `
Rename-Item "C:\node-v10.16.3-win-x64" c:\nodejs

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-nanoserver-1809 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443
COPY --from=downloadnodejs C:\nodejs\ C:\Windows\system32\

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1809 AS build
COPY --from=downloadnodejs C:\nodejs\ C:\Windows\system32\
WORKDIR /src
COPY ["DemoAngularWindows.csproj", "./"]
RUN dotnet restore "./DemoAngularWindows.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "DemoAngularWindows.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "DemoAngularWindows.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "DemoAngularWindows.dll"]

我运行docker，没有问题。但是现在我将回购推入了天蓝色的开发阶段，并创建了docker构建并将映像推送到容器注册表中。我收到错误消息，内容如下：

Invoke-WebRequest: Access to the path 'C:\nodejs.zip' is denied.
The command 'pwsh -Command $ErrorActionPreference = 'Stop';$ProgressPreference='silentlyContinue'; Invoke-WebRequest -OutFile nodejs.zip -UseBasicParsing "https://nodejs.org/dist/v10.16.3/node-v10.16.3-win-x64.zip"; Expand-Archive nodejs.zip -DestinationPath C:\; Rename-Item "C:\node-v10.16.3-win-x64" c:\nodejs' returned a non-zero code: 1

请您帮忙解决此问题？

谢谢

SPA docker Windows容器的Azure管道构建失败

我可以重现此问题：

根据错误消息，此问题被视为权限问题，请尝试创建WORKDIR，然后在该目录中执行SHELL脚本：

FROM mcr.microsoft.com/powershell:nanoserver-1809 AS downloadnodejs
RUN mkdir -p C:\nodejsfolder
WORKDIR C:\nodejsfolder
SHELL ["pwsh", "-Command", "$ErrorActionPreference = 'Stop';$ProgressPreference='silentlyContinue';"]

作为测试，该错误消失了：

希望这会有所帮助。
