在运行Jenkins的Docker容器中拒绝Dotnet构建权限

Question

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'
      }
    }
  }
}

似乎“.dotnet”文件夹在Docker容器中受到保护。是否有一种方法可以获得对此的读/写权限，或者改变它的位置？当我猛击容器时，我似乎找不到文件夹。

谢谢你的帮助。

您可以按照@colmulhall的建议设置home环境变量，但随后将docker容器主目录设置为/tmp。

若要以“dotnet”的方式执行此操作，请设置环境变量dotnet_cli_home:

environment {
    DOTNET_CLI_HOME = "/tmp/DOTNET_CLI_HOME"
}

或者在调用dotnet之前，请运行：

export DOTNET_CLI_HOME="/tmp/DOTNET_CLI_HOME"

pipeline {
    agent {
        label '!windows'
    }

    environment {
        DISABLE_AUTH = 'true'
        DB_ENGINE    = 'sqlite'
        DOTNET_CLI_HOME = "/tmp/DOTNET_CLI_HOME"
    }

    stages {
        stage('Build') {
            steps {
                echo "Database engine is ${DB_ENGINE}"
                echo "DISABLE_AUTH is ${DISABLE_AUTH}"
                sh 'printenv'
            }
        }
    }
}
