老师，您好。
我查看pod，发现有不正常的状态。

[root@mysql-01 ~]# kubectl get pod -A

其中网络插件不知道为什么有三个

kube-system   kube-flannel-ds-5g622            0/1     Init:Error              3612 (5m23s ago)   12d

kube-system   kube-flannel-ds-rh8zh            0/1     Init:CrashLoopBackOff   57 (12d ago)       12d

另外test的命名空间下的两个也有问题

test          busybox                          0/1     Pending                 0                  17h
test          nginx                            0/1     Pending                 0                  25h

用kubectl describe nodes命令查看，有以下错误信息。

老师能帮忙看下问题吗
