After I build rancher & k8s cluster, It’s work fine.  
I wanted to add worker node to cluster, I modified rancher-cluster.yml, and one woker node,

- address: 172.16.0.7  
port: 36000  
user: tars  
role: [worker]  
then:  
…/bin/rke up --config rancher-cluster.yml

I got this error:  
INFO[0031] [healthcheck] Start Healthcheck on service [kube-proxy] on host [172.16.0.7]
