k8s叢集故障二:節點為NotReady狀態
阿新 • • 發佈:2020-07-31
按照教程部署完k8s的各個節點後,獲取節點資訊時,可是發現只有作為master和同時作為node的節點狀態才是正確的:
[root@k8s-master ~]# kubectl get node NAME STATUS ROLES AGE VERSION k8s-master Ready <none> 7d22h v1.18.6 k8s1 NotReady <none> 7d21h v1.18.6 k8s2 NotReady <none> 7d21h v1.18.6
在node中檢視日誌:
7月 31 17:22:43 k8s1 kubelet[29033]: E0731 17:22:43.663415 29033 kubelet.go:2188] Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized 7月 31 17:22:48 k8s1 kubelet[29033]: E0731 17:22:48.674388 29033 kubelet.go:2188] Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized 7月 31 17:22:53 k8s1 kubelet[29033]: E0731 17:22:53.689125 29033 kubelet.go:2188] Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized
網路問題導致,經過多次排查發現:因為是有k8s-master 主機直接遷移node需要的元件到另外的機器,所以在配置檔案中有兩處一定要做出修改:
[root@k8s1 ~]# vim /opt/kubernetes/cfg/kube-proxy-config.yml
hostnameOverride: k8s1 ##主機名
[root@k8s1 ~]#vim /opt/kubernetes/cfg/kubelet.conf
--hostname-override=k8s-node1
##在重新刪除相關證書檔案:
[root@k8s1 ~]# rm /opt/kubernetes/cfg/kubelet.kubeconfig
[root@k8s1 ~]# rm -f /opt/kubernetes/ssl/kubelet*
然後重啟伺服器
