Jenkins Pipeline 流水线 – 添加节点 使用代理

Jenkins 安装在 Windows 上
Docker 在Linux 上

流程

• 将 Docker 在 Jenkins 节点中维护
• Pipeline 中指定某些阶段使用哪个节点

添加节点

Pipeline 指定节点执行

pipeline {
    agent none // stage 中指定了agent 这边必须使用 none 不指定
 
    stages { 
        stage('执行构建') {
            agent {	label 'DockerAgent-label' }  
            steps {
                sh 'docker --version' 
                echo '构建完成'
            }
        }
    }
}
