Flannel compatiblity with etcd v3.0
From my deployment process, flannel is uncompatiblity with etcd v3.0 now(2019/09/06). I am finding a way to handle this, when I starting flannel it throws this error:
E0908 20:05:41.432715 28891 main.go:382] Couldn't fetch network config: 100: Key not found (/kube-centos)
