k8s报错kubelet.go:2461] “Error getting node“ err=“node \“k8s-master\“ not found“

问题

首先最初问题:

bash 复制代码
[root@k8s-master ~]# kubectl get pods -owide --all-namespaces
The connection to the server 192.168.2.129:6443 was refused - did you specify the right host or port?

检查kubelet状态

查看kubelet status报找不到master节点

bash 复制代码
[root@k8s-master ~]# systemctl status  kubelet
● kubelet.service - kubelet: The Kubernetes Node Agent
   Loaded: loaded (/usr/lib/systemd/system/kubelet.service; enabled; vendor preset: disabled)

解决办法更新k8s集群证书

bash 复制代码
[root@k8s-master ~]# sudo kubeadm  certs renew all
[renew] Reading configuration from the cluster...
[renew] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'

certificate embedded in the kubeconfig file for the admin to use and for kubeadm itself renewed
certificate for serving the Kubernetes API renewed
certificate the apiserver uses to access etcd renewed
certificate for the API server to connect to kubelet renewed
certificate embedded in the kubeconfig file for the controller manager to use renewed
certificate for liveness probes to healthcheck etcd renewed
certificate for etcd nodes to communicate with each other renewed
certificate for serving etcd renewed
certificate for the front proxy client renewed
certificate embedded in the kubeconfig file for the scheduler manager to use renewed

Done renewing certificates. You must restart the kube-apiserver, kube-controller-manager, kube-scheduler and etcd, so that they can use the new certificates.

成功运行

bash 复制代码
[root@k8s-master ~]# kubectl get pods
