发现pod状态无论多久都是处于pending。READY字段一直是0/1,服务部署失败的原因是”中国墙“的问题导致无法下载pod启动时需要的谷歌镜像，所以我们得间接的创建所需的镜像。
补充： Pending状态表示API Server已经创建Pod，但Pod内还有一个或者多个容器没有创建，或者正在下载镜像的过程。详细的参考Pod声明周期和重启策略

##制作新镜像，因kubectl describe pod myk8s-pod-2-2707079129-1305m 提示找不到 docker.io/base-tomcat，那么我们就制作一个
[root@localhost registry.access.redhat.com]# docker tag base_tomcat:tomcat-centos docker.io/base-tomcat:v1
