}二、pipeline：Jenkinsfile注释说明
### --- 创建pod模板
pipeline {
agent {
kubernetes { //agent声明使用kubernetes
cloud 'kubernetes-default' //指定使用哪个k8s进行编译操作，执行的时候会在哪里配置k8s集群
slaveConnectTimeout 1200 //slave的超时时间，按需更改即可
yaml ''' //yaml指定它的pod文件
image: 'registry.cn-beijing.aliyuncs.com/citools/jnlp:alpine' //镜像地址为阿里云仓库
name: jnlp //jnlp和master进行通讯的
image: "registry.cn-beijing.aliyuncs.com/citools/maven:3.5.3" //启动一个maven镜像，是用来进行编译的，在编译的时候会使用maveinstall进行使用的
name: "build" //镜像的名称是build
- mountPath: "/root/.m2/" //持久化，挂载到.2，maven插件默认是挂载到/root/.m2的目录下，存放放编译的时候插件的位置
name: "volume-maven-repo" //volume名称
image: "registry.cn-beijing.aliyuncs.com/citools/kubectl:1.17.4" //kubectl，编译的时候会使用到set命令，可以使用kubectl执行set命令即可
name: "volume-kubeconfig" //kubectl的kubeconfig文件挂载进去，可以使用单个kubeconfig文件去管理多个集群，创建多集群的kubeconfig
image: "registry.cn-beijing.aliyuncs.com/citools/docker:19.03.9-git" //在docker中build镜像，在push到镜像仓库，需要使用docker客户端，在docker中push镜像时，需要使用demo进程才可以push镜像
- mountPath: "/var/run/docker.sock" //使用了宿主机的sock文件挂载到容器上，直接push镜像
volumes: //创建的一些volume
path: "/var/run/docker.sock" //sock文件，使用sock文件进行编译操作，构建操作和pod操作
path: "/usr/share/zoneinfo/Asia/Shanghai" //挂载了一个时间
- name: "volume-maven-repo" //挂载了maven依赖包
emptyDir: {} //直接使用的是空目录，若是有后端存储可以更改为后端存储，或者挂载nfs也是可以的
secretName: "multi-kube-config" //挂载了一个secret，实验时可以创建一个secret，挂载到pod中，就可以直接使用了### --- 通过pipeline生成的流水线的框架
stages {
stage('pulling Code') { //拉取代码
parallel { //parallel是并行拉取代码，执行的时候只需要执行一个，使用when参数来控制
when { //设置一个when，符合条件的情况下才会执行
stage('pulling Code by trigger') { //手动触发
stage('initConfiguration') { //生成镜像的tag
stage('Building') { //镜像构建
parallel { //和下面的stage是并行的Walter Savage Landor:strove with none,for none was worth my strife.Nature I loved and, next to Nature, Art:I warm'd both hands before the fire of life.It sinks, and I am ready to depart
