一、現象
[root@master69 nginx-demo]# kubectl get pods NAME READY STATUS RESTARTS AGE nginx-demo-deployment-59fbc48594-fq5kr 0/1 ContainerCreating 0 26s nginx-demo-deployment-59fbc48594-nrmwk 0/1 ContainerCreating 0 26s nginx-demo-deployment-59fbc48594-x5shn 0/1 ContainerCreating 0 26s
POD一直顯示建立中
二、檢視日誌

因為之前加入過叢集，所以需要先清除cni0
rm -rf /var/lib/cni/ rm -rf /etc/cni/ ifconfig cni0 down ip link delete cni0
再執行成功。
