尝试将节点添加到我的 Kubernetes 集群时如何解决超时问题？

Question

我正在尝试向我的（当前运行ning）Kubernetes 集群添加一个节点。
当我运行 kubeadm join 命令时，出现以下错误：

[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/
error execution phase preflight: couldn't validate the identity of the API Server:  
Get "https://159.65.40.41:6443/api/v1/namespaces/kube-public/configmaps/cluster-info?timeout=10s":  
net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)
To see the stack trace of this error execute with --v=5 or higher

这里是堆栈跟踪的片段

I0917 16:06:58.162180    2714 token.go:215] [discovery] Failed to request cluster-info, will try again: Get "https://*redacted*:6443/api/v1/namespaces/kube-public/configmaps/cluster-info?timeout=10s": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

这是什么意思，我该如何解决？

我忘了我的服务器上安装了防火墙

我已经按照此处找到的说明添加了端口 6443 (Kubeadm join failed : Failed to request cluster-info)，一切正常！
