在运行Jenkins的Docker容器中拒绝了Dotnet构建许可

问题描述

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.

I am trying to build a .NET application using Jenkins. The Jenkins instance is running in a Docker container.

我的Jenkins文件如下:

My Jenkinsfile is as follows:

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，我在Jenkins构建输出中看到以下错误:

When I attempt the build I am seeing the following error in the Jenkins build output:

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.Cli.Program.ProcessArgs(String[] args, ITelemetry telemetryClient)
   at Microsoft.DotNet.Cli.Program.Main(String[] args)

似乎'.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? bash进入容器时，似乎找不到该文件夹​​.

It appears that the '.dotnet' folder is protected in the Docker container. Is there a way of getting read/write permission on this, or a way of changing it's location? I can't seem to find the folder when I bash into the container.

感谢您的帮助.

推荐答案

该问题似乎与尝试将数据写入Docker容器('/')的顶层有关.

The issue appeared to be linked to trying to write data to the top level of the Docker container ('/').

在Jenkins文件中添加以下内容可确保设置主目录，并可以在具有正确权限的位置创建.dotnet文件夹.

Adding the following to the Jenkinsfile ensures that the home directory is set and the .dotnet folder can be created in a location with correct permissions.

environment {
   HOME = '/tmp'
}
