kubeadm 安装出这个错误，有会的么。

运行后错误如下。
rror execution phase preflight: [preflight] Some fatal errors occurred:
        [ERROR CRI]: container runtime is not running: output: E0925 19:19:06.216088   12185 remote_runtime.go:948] "Status from runtime service failed" err="rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"
time="2022-09-25T19:19:06+08:00" level=fatal msg="getting status of runtime: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"
, error: exit status 1
[preflight] If you know what you are doing, you can make a check non-fatal with `–ignore-preflight-errors=…`
To see the stack trace of this error execute with –v=5 or higher

你的cri没有运行，你如果用的是docker ce做cri，那你得安装一下

跟着文档做还是挺简单的，但是国内机很多东西不能访问就很**，要练习还不如整几天国外小鸡

行，我试试国外的机器

老哥，我这是成功了吧。我后面的步骤就是弄其他机器安装后，加入这个是吧？然后就是安装什么其他的web管理页面。

其他node直接kubeadm join加入集群就行了，当然该装的环境比如kubeadm kubectl都要装才行哈，还有网络组件calico也得装一下，新学建议先玩命令行吧，敲熟了再用dashboard ，文档中搜dashboard 也有安装教程，第三方的如portainer啥的也可以google看下呗

portainer 能管理多个机器么？我没装什么calico

sudo yum install -y kubelet kubeadm kubectl –disableexcludes=kubernetes

sudo systemctl enable –now kubelet

//解决那个container runtime is not running 错误，这样就行了。
rm -rf /etc/containerd/config.toml
systemctl restart containerd

kubeadm init –apiserver-advertise-address=自己的ip
–image-repository registry.aliyuncs.com/google_containers
–service-cidr=10.1.0.0/16
–pod-network-cidr=10.244.0.0/16

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
systemctl daemon-reload
之后就都是Ready了
