This is a...

• Feature Request
• [x ] Bug Report

Problem:
In the CentOS guide for Kubernetes installation for etcd to be configure it says this:

• Configure ETCD to hold the network overlay configuration on master: Warning This network must be unused in your network infrastructure! 172.30.0.0/16 is free in our network.

$ etcdctl mkdir /kube-centos/network

But running the above command will show:

$ etcdctl mkdir /kube-centos/network
Error: client: etcd cluster is unavailable or misconfigured
error #0: dial tcp 127.0.0.1:2379: getsockopt: connection refused
error #1: dial tcp 127.0.0.1:4001: getsockopt: connection refused

Proposed Solution:
First etcd should be start to avoid the error by excuting:

$ systemctl start etcd
