那是我的 Jenkinsfile。

pipeline {
    agent none
    stages {
        stage('Build') {
            agent {
                docker {
                    image 'python:3-alpine'
                }
            }
            steps {
                sh 'pip install --user -r requirements.txt'
                sh 'python WebChecker.py'
            }
            post {
                always {
                    junit 'output.xml'
                }
            }
        }
    }
}

当我在 Jenkins 中运行它时，我得到了关注

script returned exit code 1

那么我执行 sudo pip install ....

我收到以下错误:

[urltester] Running shell script

+ sudo python -m pip install --user -r requirements.txt

/Users/me/.jenkins/workspace/urltester@tmp/durable-e36d9731/script.sh: line 1: sudo: not found

script returned exit code 127

然后我删除了 sudo 并尝试使用虚拟环境:

pipeline {
    agent none
    stages {
        stage('Build') {
            agent {
                docker {
                    image 'python:3-alpine'
                }
            }
            steps {
                sh 'virtualenv venv --distribute'
                sh 'source venv/bin/activate '
                sh 'pip install --user -r requirements.txt'
                sh 'python WebChecker.py'
            }
            post {
                always {
                    junit 'output.xml'
                }
            }
        }
    }
}

但是后来我得到了和我尝试sudo时一样的东西，但是这次没有找到virtualenv。

我的最终目标是能够运行我的 python 脚本。此 python 脚本将在其同一目录中生成一个 xml 文件。然后 Jenkins 应该读取这个 xml 文件。我尝试使用 Docker，但并没有走得太远。那我该怎么办？

最佳答案

正如 tftd 所写，将 HOME 更改为可写目录，例如:

pipeline {
    agent none
    stages {
        stage('Build') {
            agent {
                docker {
                    image 'python:3-alpine'
                }
            }
            steps {
                withEnv(["HOME=${env.WORKSPACE}"]) {
                    sh 'pip install --user -r requirements.txt'
                    sh 'python WebChecker.py'
                }
            }
            post {
                always {
                    junit 'output.xml'
                }
            }
        }
    }
}
