Error: context deadline exceeded
原因：

k8s现在使用的是etcd v3，必须提供ca、key、cert，否则会出现Error: context deadline exceeded
不加–endpoint参数时，默认访问的127.0.0.1:2379，而使用–endpoint参数时，必须提供ca,key,cert。

root@hqa-master-01:~# etcdctl --endpoints=$ETCD_ENDPOINTS \

–cert=/srv/etcd/etc/ssl/etcd.crt
–key=/srv/etcd/etc/ssl/etcd.key
–cacert=/srv/etcd/etc/ssl/ca.crt
