Jenkinsfile中指定节点构建

流水线支持两种语法：声明式（在 Pipeline 2.5 引入）和脚本式流水线。

声明式Jenkinsfile (Declarative Pipeline，声明式流水线)

pipeline {
    agent {label 'openjdk8'}

    stages {
        stage('Hello') {
            steps {
                echo 'Hello World'
            }
        }
    }
}

通过agent type来指定节点， Must be one of [any, kubernetes, label, none]

Jenkinsfile (Scripted Pipeline，脚本式流水线)

node ('openjdk8') {
    stage('Hello') {
        echo 'Hello World'
    }
}
