docker - Jenkins 的示例管道显然无法正常工作

Question

我已经安装了装有Jenkins 2.190.1的Ubuntu 18.04，并尝试运行简单的管道脚本

pipeline {
    agent {
        docker { image 'node:7-alpine' }
    }
    stages {
        stage('Test') {
            steps {
                sh 'node --version'
            }
        }
    }
}

运行此命令会拉出镜像，然后似乎卡住并且什么也没发生，但是作业仍在进行中。

当我取消工作时，日志显示

我的设置有什么问题？还是要研究什么问题？

谢谢

显然Alpine Node容器没有引导到 shell 中。您需要在脚本中指定 shell 程序:

sh '''#!/bin/sh
    node --version
'''
