kubectl 报错 couldn‘t get current server API group list:

🔍场景一：刚搭建完成k8s集群，查看pod报如下错

[root@node02 ~]# kubectl get pod

The connection to the server localhost:8080 was refused - did you specify the right host or port?

✅解决方法：准备kubectl 配置文件
在master节点上操作

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

🔍场景二：集群搭建完成，但关机后，查看pod 报如下错

报错信息：

E0914 11:51:02.84256214052 memcache.go:265]"Unhandled Error"'couldn't get current server API group list: Get \"https://192.168.00,10:6443/api?timeout=32s\": dial tcp 192.168.100.10:6443: conneerct: connection refused

✅解决方步骤

1.检查kubelet服务是否运行2.docker ps -a 查看k8s-etcd容器是否关闭3.尝试启动etcd容器，并重启kubectl 服务

4.若还不行，则启动api server 容器再试
