Host의 IP가 여러 개인 경우 에러

Line 38 in f1d7d4d

    
           kubeadm init --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=`hostname -i` --token-ttl=0

kubeadm을 실행할 때 하나의 IP 주소만 넘어가야 하는가 봅니다.

아래와 같이 여러 IP가 있는 경우 kubeadm 실행시 에러가 생깁니다.

# hostname -i
129.254.188.254 172.17.0.1 fe80::f816:3eff:fe16:6f31

임시(?) 패치를 push하려니 잘 안되서 바로 올립니다.
