现在的集群是 一个master 一个slave ，
master 的运行状态良好。
但是save加入calico/node 的时候 ，获取到的描述信息是
node.kubernetes.io/unschedulable:NoSchedule

他获取的不因该是 master的IP吗怎么是localhost了。
我看了master上面 calico绑定的也是 127.0.0.1
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 127.0.0.1:9099 0.0.0.0:* LISTEN 17421/calico-node

tcp 0 0 127.0.0.1:10257 0.0.0.0:* LISTEN 16148/kube-controll
怎么才能绑定外网IP呢。
具体的日志信息
node.kubernetes.io/unschedulable:NoSchedule

亲，calico不在本课程范围内。但通过你给出的日志来看，你看一下安装calico时，calico的yaml文件中关于相关pod 的readiess和liveness的探针定义是怎么写的。或到calico项目的issue中看看是否有人遇到与你相似的问题了。祝学习愉快！
