Kubectl记录pods_name：服务器拨号tcp xx.xx.xx.xx：10250时出错：connect：主机没有路由

时间：2020-08-27 23:04:12

标签： docker kubernetes centos

我创建了一个具有1个主设备和2个工作器的kubernetes集群。当我创建一个Pod时，一切都成功了，但是后来，我发现Pod运行不正常，从一分钟到另一分钟，它崩溃了，它指示CrashLoopBackOff错误，并且当我尝试查看其日志时，出现另一个错误，是“服务器拨号tcp xx.xx.xx.xx：10250：连接时出错：连接主机没有路由”

我正在使用CentOS7
