helm-查找版本问题

今天想升级一下prometheus,发现查找出来的版本比较低，并不是最新版本：

client@local:~$ helm search prometheus
NAME                     	VERSION	DESCRIPTION                                       
stable/prometheus        	3.1.0  	Prometheus is a monitoring system and time seri...
stable/weave-cloud       	0.1.0  	Weave Cloud Agents

检查helm版本：

client@local:~$ helm version --tiller-namespace=default
Client: &version.Version{SemVer:"v2.5.0", GitCommit:"012cb0ac1a1b2f888144ef5a67b8dab6c2d45be6", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.5.0", GitCommit:"012cb0ac1a1b2f888144ef5a67b8dab6c2d45be6", GitTreeState:"clean"}

所以重新初始化一下客户端：

client@local:~$ helm init --client-only --tiller-namespace=default
Creating /home/client/.helm 
Creating /home/client/.helm/repository 
Creating /home/client/.helm/repository/cache 
Creating /home/client/.helm/repository/local 
Creating /home/client/.helm/plugins 
Creating /home/client/.helm/starters 
Creating /home/client/.helm/cache/archive 
Creating /home/client/.helm/repository/repositories.yaml 
$HELM_HOME has been configured at /home/zyh/.helm.
Not installing tiller due to 'client-only' flag having been set
Happy Helming!

再次查找，版本已经并为最新版本了
