Declarative pipeline

The basic framework of declarative pipeline script is as follows , What needs to be noticed is ：

• The outermost pipeline{} Represents the entire pipeline , Include all the concrete implementations
• agent Fields are essential
• stages{} There can only be one structure , But a stages{} A structure can contain multiple stage{}
• Every stage{} Must have a specific name , Every stage{} There can only be one steps{}

pipeline {
    
    agent any //agent  Specify the running node of this pipeline task later , It is generally a fixed node ip Address 
              //agent any Indicates that the pipeline task is specified to run on any node 
    stages {
    
        stage('Build') {
     // Define build phase 
            steps {
    
                //  Perform specific build tasks ...
            }
        }
        stage('Test') {
     // Define the unit test phase 
            steps {
    
                //  Perform specific test contents ...
            }
        }
        stage('Deploy') {
     // Define deployment phase 
            steps {
    
                //  Perform specific deployment operations ...
            }
        }
    }
