Question

Jenkins 版本：-

Jenkins - 2.277.1 LTS.

我的 Dockerfile:-

FROM maven:3.6.0-jdk-13
RUN useradd -m -u 1000 -s /bin/bash jenkins

我的声明式管道：-

pipeline {
    agent {
        label "VM-Linux-Agent"
    }
    environment {
        DOCKERFILE = "Dockerfile"
    }

    stages {
        stage("Checkout") {
            steps {
                  git(
                  url: 'git@gitlab.company.com:maven-prj-group/mavenapp.git',
                  branch: "master"
                )
                
            }
        }

        stage("Build") {
                agent {
                   dockerfile {
                   filename DOCKERFILE   
                   args "-v $WORKSPACE:/var/maven" 
               }
            }   
            steps {
                sh "mvn clean install"
            }
        }
    }
}

从 Jenkins master 我已将 Linux 服务器配置为节点 VM-Linux-Agent 并使用此节点管道作业 code checkout 正在发生并进一步使用 Dockerfile 构建一个 docker 容器然后运行构建其他人对 docker 本身的步骤不起作用。它显示以下错误。

Build 步骤而不是在 docker 容器上运行，而是在 master 上运行，然后失败。因为我只想从我的节点系统（这是 Docker 主机）在 docker 容器上运行 build + test 步骤。那么我如何在我的声明性管道中解决这个问题？请让我知道如何做到这一点。提前致谢。

在管道代码部分 global agent 替换为 none 并检查特定从属设备上的代码（在我的情况下为 VM-Linux-Agent）添加为 agent label。

以下代码对我有用。

pipeline {
    agent none
 
    stages {
        stage("Checkout") {
            agent {
                label "VM-Linux-Agent"
            }
            steps {
                  git(
                  url: 'git@gitlab.company.com:maven-prj-group/mavenapp.git',
                  branch: "master"
                )
            }
        }

        stage("Build") {
                agent {
                   dockerfile {
                   filename 'Dockerfile'  
                   label 'VM-Linux-Agent'
                   args "-v /home/user/maven:/var/maven" 
               }
            }   
            steps {
                sh "mvn clean install"
            }
        }
    }
}
