《Kubernetes 排错指南-006》error execution phase couldn‘t initialize a Kubernetes cluster

系统环境：

VMware ESXi 7.0.2
Ubuntu 20.04 LTS
Docker 20.10.8
Kubernetes 1.22.1
Node: master

执行命令：

$ kubeadm init

报错如下：

Unfortunately, an error has occurred:timed out waiting for the conditionThis error is likely caused by:- The kubelet is not running- The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:- 'systemctl status kubelet'- 'journalctl -xeu kubelet'Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI.Here is one example how you may list all Kubernetes containers running in docker:- 'docker ps -a | grep kube | grep -v pause'Once you have found the failing container, you can inspect its logs with:- 'docker logs CONTAINERID'error execution phase wait-control-plane: couldn't initialize a Kubernetes cluster

报错说明：

这个问题一般是由虚拟机或软件包配置错误错误引起的，需要修改 Docker Cgroup 的驱动程序。

解决方案:

$ vi /etc/docker/daemon.json{"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"storage-driver": "overlay2","storage-opts": ["overlay2.override_kernel_check=true"],"registry-mirrors" : ["https://ot2k4d59.mirror.aliyuncs.com/"],"graph": "/data/docker"
}$ systemctl daemon-reload
$ systemctl restart docker

将 Docker Cgroup 驱动程序修改为 systemd 然后加载配置，重新启动 Docker 服务。
