Jenkins Pipeline 自动化构建java项目并部署到kubernetes集群

一、镜像tag使用时间变量，配置如下：
1.1、首先在Jenkins的插件管理中安装Date Parameter插件：Manage Jenkins --> Plugin Manager --> Avaiable中搜索Date Parameter。
1.2、在Jenkins中配置如下：

二、编写Pipeline脚本

pipeline {
    agent any

    stages {
        stage('Printenv') {
           steps {
                script{
                  sh 'printenv'
           }
       }
	 }
	 
        stage('pull code') {
            steps {
                git branch: '${branch}', credentialsId: 'jenkins_226', url: 'git@gitlab.test.cn:hc-backed/hc-risk/hc-risk-test.git'
                updateGitlabCommitStatus(name: env.STAGE_NAME, state: 'success')
                   script{
                       env.BUILD_TASKS = env.STAGE_NAME + "√..." + env.TAB_STR
                   }
            }
        }
        stage('Code Build'){ 
	        steps {
                retry(2) { sh "/opt/maven/bin/mvn  -U -pl risk-business/business-service -am -Dmaven.test.skip=true clean package" }
			    updateGitlabCommitStatus(name: env.STAGE_NAME, state: 'success')
                   script{
                       env.BUILD_TASKS += env.STAGE_NAME + "√..." + env.TAB_STR
                }
             }  
         }
        stage('Docker Build'){ 
	        steps {
                retry(2) { 
sh '''
