$ kubectl get pods --all-namespaces
The connection to the server localhost:8080 was refused - did you specify the right host or port?
原因：
kube-apiserver默認(rèn)只啟動(dòng)安全訪問接口6443井佑，而不啟動(dòng)非安裝訪問接口8080
解決方案：
$ sudo vi /etc/kubernetes/manifests/kube-apiserver.yaml
# 修改--insecure-port=8080
--insecure-port=0
重啟kube-apiserver
$ sudo docker ps |grep 'kube-apiserver'
