Ubuntu22.04LTS部署Kubernetes遇连接拒绝及CRI运行时错误求助

环境 #

Ubuntu 22.04 LTS桌面机器，已按官方文档安装kubeadm、kubelet和kubectl。

遇到的问题 #

1. kubectl集群信息查询失败 #

执行sudo kubectl cluster-info报错：

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
The connection to the server localhost:8080 was refused - did you specify the right host or port?

2. kubectl配置为空 #

执行kubectl config view结果：

apiVersion: v1
clusters: null
contexts: null
current-context: ""
kind: Config
preferences: {}
users: null

3. /etc/kubernetes目录状态 #

目录下仅存在一个空的manifest文件夹。

4. kubeadm init预检错误 #

执行sudo kubeadm init时触发预检失败：

[init] Using Kubernetes version: v1.25.4
[preflight] Running pre-flight checks
    [WARNING Swap]: swap is enabled; production deployments should disable swap unless testing the NodeSwap feature gate of the kubelet
    [WARNING SystemVerification]: missing optional cgroups: blkio
error execution phase preflight: [preflight] Some fatal errors occurred:
    [ERROR CRI]: container runtime is not running: output: E1207 13:27:13.819798   50381 remote_runtime.go:948] "Status from runtime service failed" err="rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"
time="2022-12-07T13:27:13-08:00" 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

5. kubeadm镜像拉取失败 #

执行sudo kubeadm config images pull --v=5报错：
