[wait-control-plane] Waiting for the kubelet to boot up the control plane as static Pods from directory “/etc/kubernetes/manifests”. This can take up to 4m0s
报错
[kubelet-check] Initial timeout of 40s passed.
[kubelet-check] It seems like the kubelet isn’t running or healthy.

以上k8s 错误使用与 比较新的版本 1.19-1.22 都会在k8s初始化的时候卡在这里
这是我的初始化:
kubeadm init --kubernetes-version=v1.22.2 --image-repository registry.aliyuncs.com/google_containers --pod-network-cidr=10.244.0.0/16 --service-cidr=10.96.0.0/12 --ignore-preflight-errors=Swap

新建vim /etc/docker/daemon.json
因为这个文件是没有所以需要新建

{
  "exec-opts": ["native.cgroupdriver=systemd"]
}
···
然后重启服务

systemctl daemon-reload
systemctl restart docker

修改kubelet配置
修改kubelet的配置文件
10-kubeadm.conf 不一定在以下路径,可以运行 
systemctl  status kubelet 查看
新建/etc/systemd/system/kubelet.service.d/10-kubeadm.conf文件,并添加以下内容。
···
Environment="KUBELET_KUBECONFIG_ARGS=--bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --kubeconfig=/etc/kubernetes/kubelet.conf --cgroup-driver=cgroupfs"
···
重启kubelet

systemctl daemon-reload
systemctl restart kubelet

因为k8s 说不在支持docker了,估计1.18版本开始有报警

[WARNING IsDockerSystemdCheck]: detected "cgroupfs" as the Docker cgroup driver. The recommended driver is "systemd". Please follow the guide at https://kubernetes.io/docs/setup/cri/


所以,需要开启兼容模式。
在然后k8s 放弃docker兼容,后续如何走,走一步看一步了。
