这两天重新部署kubernetes，在部署应用的时候总是部署不上，报以下错误(我自己换行了一下，更好看错误)
failed to set up sandbox container "077e2fc1c141a622aaf9337b760b2c1b98d4357e35ababcc768f130dee2cd8d1" network for pod "mysql-6h5jk":

最后是盲猜网络插件有问题，于是重新安装 Calico 解决了
[root@master ~]# kubectl apply -f https://docs.projectcalico.org/v3.11/manifests/calico.yaml
configmap/calico-config created
