jenkins - 无法在 docker 代理中运行 sh 步骤 : script. sh Not Found

Question

尝试运行以下声明性管道时:

pipeline {
    agent { docker 'alpine' }
    stages {
        stage('Test') {
            steps {
                sh('printenv')
            }
        }
    }
}

我收到错误:

监控管道时 @tmp目录在运行时我可以看到 script.sh短期创建。当管道尝试在正在运行的容器中执行它时，我无法判断它是已创建还是已删除。

一些系统细节

Jenkins 作为安装了 docker 的单节点系统运行。

Jenkins v2.60.1
(all plugins fully updated)

docker --version
Docker version 17.06.0-ce, build 02c1d87

Answer 1

具有相同的设置(EC2 实例上的单个 Jenkins 2.73.1 主机，而不是容器内，使用 Docker 17.09.0-ce)和相同的行为，具有声明性和脚本化管道。
如果您指定，它会尝试在主机本身上运行脚本

sh 'sh ./yourscript.sh'

或者

sh './yourscript.sh'

而不是 sh 'script.sh'
