k8s常见报错

1.　　kubeadm初始化的时候，报错：detected "cgroupfs" as the Docker cgroup driver. The recommended driver is "systemd"

　　　　解决方法：

　　　　1.　　编辑docker配置文件/etc/docker/daemon.json　　　

"exec-opts": ["native.cgroupdriver=systemd"]
systemctl daemon-reload
systemctl restart docker

　　　　2.　　但是这会导致另外一个问题出现：failed to run Kubelet: failed to create kubelet: misconfiguration: kubelet cgroup driver: "cgroupfs" is different from docker cgroup driver: "systemd"

　　　　　　　　修改文件：vi /var/lib/kubelet/kubeadm-flags.env

　　　　　　　　KUBELET_KUBEADM_ARGS="--cgroup-driver=systemd --network-plugin=cni --pod-infra-container-image=registry.aliyuncs.com/google_containers/pause:3.1"
