在node节点内部使用kubectl：

root@multinode-demo-m02:/# ps aux | grep kubelet
root         218  3.1  1.6 2066316 62516 ?       Ssl  07:35   0:29 /var/lib/minikube/binaries/v1.30.0/kubelet --bootstrap-kubeconfig=/etc/kubernetes/bootstrap-kubelet.conf --config=/var/lib/kubelet/config.yaml --hostname-override=multinode-demo-m02 --kubeconfig=/etc/kubernetes/kubelet.conf --node-ip=192.168.49.3
root        3941  0.0  0.0   3456   720 pts/1    S+   07:51   0:00 grep --color=auto kubelet

root@multinode-demo-m02:/# kubectl get pods --kubeconfig=/etc/kubernetes/kubelet.conf

在etcd容器内部使用etcdctl：

etcdctl --endpoints=https://192.168.58.2:2379 --cert=/var/lib/minikube/certs/etcd/peer.crt --key=/var/lib/minikube/certs/etcd/peer.key --cacert=/var/lib/minikube/certs/etcd/ca.crt get /registry/configmaps --prefix --keys-only

--end--
