1.新建部署job fangliProvider部署测试环境

简单测试参数化构建

流水线脚本：

podTemplate(name: 'jenkins-slave', cloud: 'kubernetes',
  namespace: 'jenkins', label: 'jenkins-slave',volumes: [
    hostPathVolume(mountPath: '/usr/bin/kubectl', hostPath: '/usr/bin/kubectl'),
    hostPathVolume(mountPath: '/var/jenkins_home/', hostPath: '/var/jenkins_home/')
]) 
  {
  node('jenkins-slave') {

    stage('apply update') {
      container('jnlp') {
          sh '''
          kubectl apply -f $deployfile -n testfl
 
          '''
      }
    }

2.错误的解决

a. 云环境cloud: 'kubernetes' 不存在

解决：配置云环境，没插件下载k8s对应插件

系统管理》节点管理》》configure clouds》》add a new Cloud

因为jenkins已经是k8s管理的容器，默认连接测试通常会成功。

 

b.  运行流水线pod模板 k8s会自动创建 jenkins从节点slave（也是一个pod）去跑这个job.

从节点运行不成功。5000端口不可达

解决：

   1. jenkins-service.xml  配置5000端口

apiVersion: v1
kind: Service
metadata:
  name: jenkins
spec:
  type: NodePort
  ports:
    - name: web
      port: 8080
      targetPort: web
      nodePort: 32634
    - name: agent
      port: 50000
      targetPort: agent
  selector:
    app: jenkins

2. 部署文件配置5000容器端口 name和jenkins-service.xml对应

3.最重要的一点，jenkins配置通道地址 IP+端口 前面不要有http之类
