我的Kubernetes群集目前遇到了问题，需要一些帮助。直到今天，一切都很顺利。但是，在我的Ubuntu系统上执行了一次更新之后，我无法建立从我的工作环境到kubernetes集群的连接。
在执行kubectl get pods命令时，我遇到以下错误消息：
E0805 09:59:45.750534 234576 memcache.go:265] couldn’t get current server API group list: Get "http://localhost:3334/api?timeout=32s": EOF
以下是我的集群设置的详细信息：Kubernetes 1.27，裸机，主机系统为Ubuntu 20.04
我将非常感谢任何关于解决这个问题的指导或见解。

这是一个身份验证问题-API确保kubeconfig存在并纠正执行的用户命令。
这通常在引导集群时观察到，并且忘记在下面运行。

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

尝试

kubectl get nodes -v=10

并查找错误。

我也遇到了同样的错误，这是因为kubectl找不到要连接的集群信息。

使用kubectl config view测试，它应该返回空配置

kubectl config view apiVersion：v1群集：空上下文：null当前上下文：“”kind：配置首选项：{}用户：空
解决方案：

手动配置集群或安装minikube，它将使用任何hypervisor或docker配置单个集群节点N.B：需要有一个虚拟机管理程序，例如：已安装VirtualBox或Docker
按照minikube安装并启动minkube https://minikube.sigs.k8s.io/docs/start/

    minikube
    type: Control Plane
    host: Running
    kubelet: Running
    apiserver: Running
    kubeconfig: Configured```

再次测试，环境详细信息应该返回一些信息，而不是像以前一样为空

```kubectl config view 
  apiVersion: v1
  clusters:
  - cluster:
      certificate-authority: /Users/rako/.minikube/ca.crt
      extensions:
      - extension:

          provider: minikube.sigs.k8s.io
          version: v1.31.2
        name: cluster_info
      server: https://127.0.0.1:64784

我在重新启动我的节点后遇到了这个错误。我注意到我的containerd被禁用使用sudo systemctl status containerd
为了解决这个问题，我重新启动了容器sudo systemctl restart containerd
