运行Jenkins的Docker容器中的Dotnet构建许可被拒绝

我正在尝试使用Jenkins构建.NET应用程序。Jenkins实例在Docker容器中运行。

我的Jenkinsfile如下：

pipeline {
  agent {
    docker {
      image 'microsoft/dotnet:2.1-sdk'
      registryUrl 'https://index.docker.io/v1/'
    }
  }
  stages {
    stage('Build') {
      steps {
        sh 'dotnet build MyApplication/Application.csproj -c Release -o /app'
      }
    }
    stage('Test') {
      steps {
        sh 'dotnet test MyApplication/Application.csproj -c Release -r /results'
      }
    }
  }
}

当我尝试构建时，在Jenkins构建输出中看到以下错误：

System.UnauthorizedAccessException: Access to the path '/.dotnet' is denied. ---> System.IO.IOException: Permission denied
   --- End of inner exception stack trace ---
   at System.IO.FileSystem.CreateDirectory(String fullPath)
   at System.IO.Directory.CreateDirectory(String path)
   at Microsoft.Extensions.EnvironmentAbstractions.DirectoryWrapper.CreateDirectory(String path)
   at Microsoft.DotNet.Configurer.FileSentinel.Create()
   at Microsoft.DotNet.Configurer.DotnetFirstTimeUseConfigurer.Configure()
   at Microsoft.DotNet.Cli.Program.ConfigureDotNetForFirstTimeUse(INuGetCacheSentinel nugetCacheSentinel, IFirstTimeUseNoticeSentinel firstTimeUseNoticeSentinel, IAspNetCertificateSentinel aspNetCertificateSentinel, IFileSentinel toolPathSentinel, Boolean hasSuperUserAccess, DotnetFirstRunConfiguration dotnetFirstRunConfiguration, IEnvironmentProvider environmentProvider)
   at Microsoft.DotNet.Cli.Program.ProcessArgs(String[] args, ITelemetry telemetryClient)
   at Microsoft.DotNet.Cli.Program.Main(String[] args)

看来'.dotnet'文件夹在Docker容器中受到保护。有没有办法获得对此的读写权限，或者改变它的位置？当我猛扑到容器中时，似乎找不到该文件夹​​。

谢谢你的帮助。
