master节点配置

kubelet cgroup driver 必须要和docker一致

sed -i "s/cgroup-driver=systemd/cgroup-driver=cgroupfs/g" /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

kubeadm init

flannel要求cgroup是cgroupfs 网络

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/v0.9.1/Documentation/kube-flannel.yml

kubeadm init --pod-network-cidr=10.244.0.0/16 --kubernetes-version=v1.10.1

### 查看dns状态
```bash
kubectl get pods --all-namespaces

Node节点配置

必须要有kube-proxy, kube-pause flannel
