我使用minikube创建了一个单节点Kuberenetes集群，并在其上安装了helm。但是在执行helm ls和helm install命令时遇到问题。这是我面临的这个问题：
"Get http://localhost:8080/api/v1/namespaces/kube-system/configmaps?labelSelector=OWNER%!D(MISSING)TILLER: dial tcp 127.0.0.1:8080: connect: connection refused".
这些pod正在kube-system命名空间
上运行ubuntu@openshift:~$ kubectl get po -n kube-system
