问题:无法通过 Jenkins 声明式管道在 Docker 映像中作为代理进行 pip 安装

我在通过 Jenkins 声明性管道运行 Docker 的权限方面还有另一个问题。我想通过 Docker 容器中的 Jenkins 作业构建和发布 Python 包:

pipeline {

  agent {
    docker {
      image 'python:3.7'
      label 'docker && linux'
    }
  }

  environment {
    PACKAGE_VERSION = readFile 'VERSION'
  }

  stages {

    stage('Package') {
      steps {
        sh 'python -V'
        sh 'python -m pip install -r requirements.txt --user --no-cache'
        sh 'python setup.py sdist'
      }
    }

    stage('Deploy') {
      steps {
        ...
      }
    }

  }

  post {
    always {
      cleanWs()
    }
  }

}

但是,由于PermissionError,我不允许pip install:

+python -m pip install -r requirements.txt --user --no-cache 已满足要求:/usr/local/lib/python3.7/site-packages 中的 setuptools(来自 -r requirements.txt(第 1 行) )) (40.0.0) 收集 pytest(来自 -r requirements.txt(第 2 行))

由于 EnvironmentError 无法安装软件包:[Errno 13] Permission denied: '/.local' 检查权限。

如何修复这些权限?

解答

我发现了我自己认为更漂亮的解决方案:

stage("Python Test") {
  agent { 
    docker {
      label "docker && linux" 
      image "python:3.7"
    }
  }
  steps {
    withEnv(["HOME=${env.WORKSPACE}"]) {
      sh "pip install -r requirements.txt --user"
      # python stuff
    }
  }
  post {
    cleanup {
      cleanWs()
    }
  }
}

此解决方法完全围绕问题本身,在用户级别安装软件包。这里的问题是 HOME 目录最初也不是可写的,因此会覆盖 HOME 目录。
