kube-proxy CrashLoopBackOff
问题如下:
kubectl get pods -A -owide
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES

一番查找问题后,发现是犹豫master有2个默认网关导致的。估计是混淆了。
ip route show default
default via 192.168.56.1 dev enp0s3 proto static
default via 192.168.1.1 dev enp0s8 proto static
于时删除一个就好了:sudo ip route del default via 192.168.1.1
kubectl get pods -A -owide
