运行命令进入pod
kubectl exec -it nginx-3449338310-sffj4 /bin/bash
发现报错如下
Error from server: error dialing backend: dial tcp 192.168.222.137:10250: getsockopt: connection refused
发现根本原因是node节点上的/etc/kubernetes/kubelet配置文件中如下：
KUBELET_ADDRESS="--address=127.0.0.1"
此处应该更改为
KUBELET_ADDRESS="--address=192.168.222.137"
更改配置文件之后分别重启node节点上的kubelet
systemctl restart kubelet
