Question

我正在尝试在docker容器中运行构建步骤。这是我的Jenkinsfile

    pipeline {
        agent { label 'slave1' }
        stages {
            stage ('Build') {
                agent {
                    docker {image 'node:8'}
                }
                steps {
                    sh "npm install"
                }
            }
        }
        post {
            failure {
                script {
                    echo "TestRail failed"
                }
            }
        }
    }

但是步骤失败并显示以下错误

    [Frontend@2] Running shell script
    + npm install
    npm WARN mycloud@1.0.0 No repository field.

    [Pipeline] }
    $ docker stop --time=1 56e0023a9538d890a72a07bc3e57aa99b6c92d0adfc99f8e70117dd143e3d22b

当我手动运行docker容器然后执行npm install时，一切都会按预期进行。

如果以根-u 0:0的身份运行容器，则npm install通过

            agent {
                docker {
                    image 'node:8'
                    args '-u 0:0'
                }
            }

但是jenkins工作空间清理失败，显示为：

在这里，我尝试在docker容器中运行构建过程，而不是在构建机器上运行，这样，我就不必在构建机器上安装软件包，它将来自容器映像。

我在这里想念什么？

Answer 1

当前我无权访问服务器，因此无法对其进行测试，但是您是否尝试过skipDefaultCheckout，然后在docker阶段从存储库中检出？

pipeline {
    agent { label 'slave1' }

    options {
        skipDefaultCheckout true
    }

    stages {
        stage ('Build') {
            agent {
                docker {image 'node:8'}
            }
            steps {
                checkout scm
                sh "npm install"
            }
        }
    }
    post {
        failure {
            script {
                echo "TestRail failed"
            }
        }
    }
}

Answer 2

使用cloudbees中的docker step代替将其用作代理。这样做，您将在master上签出并将工作区作为卷挂载到docker（由docker插件隐式完成）。

您的Jenkins用户的用户ID是什么？据我记得，如果您的詹金斯用户的ID为1000，那么您就不必覆盖该用户，因为默认节点docker映像的ID为1000，并且不应该存在任何文件权限问题（用于删除文件）。

请原谅我机器上没有的语法错误

def image = docker.image(‘node:latest’)
image.pull()
image.inside(dockerOptions) {
   sh “npm”
   // my other logic
  }

詹金斯管道建立在容器内
