导读 Kubernetes是一个开源的，用于管理云平台中多个主机上的容器化的应用，Kubernetes的目标是让部署容器化的应用简单并且高效（powerful）,Kubernetes提供了应用部署，规划，更新，维护的一种机制。

前提条件是，有storageclass，利用pvc 创建持久化存储 创建kube-ops namespace

这里创建opspvc 另外把accessmode 换成readwritemany，因为会有多个pod 进行读写

然后部署jenkins master deployment如下

分配权限，配置rbac如下
apiVersion: v1
kind: ServiceAccount
metadata:
  name: jenkins
  namespace: kube-ops

安装k8s 插件，与k8s 目标集群进行远程连接

因为是腾讯云，并没有提供tls 客户端认证，所以直接利用账号密码，进行认证，记得，禁用https 证书检查,jenkins和k8s 就集成好了

划重点！！！：jenkins地址，这里我这里写的是内网地址以及暴露了50000端口（用来与slave 建立通信使用），因为master 和slave 分别在不通的k8s 集群里，那么需要远程进行联通，而jenkins-ui 我是以ingress 的方式对外暴露

slave 的配置

这里需要注意的是标签列表，这里填写的标签，需要在slave 所在k8s 集群的节点上进行标注，而这个名字，是label这个字段里的key 并未是value，这里要注意

job 里配置

这个意思就是 slave 会尽可能的在这个节点build
