Every system should have:

systemctl stop firewalld; systemctl disable firewalld

yum -y install ntpd && systemctl start ntpd && systemctl enable ntpd

To install a master node, you need to do the following:

yum -y install etcd kubernetes-master

Make sure /etc/etcd/etcd.conf contains this line:

ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"

Make sure /etc/kubernetes/apiserver contains this:

4. Start master node services:

for S in etcd kube-apiserver kube-controller-manager kube-scheduler; do 
  systemctl restart $S
  systemctl enable $S
done

1. Install flannel and kubernetes-node:

yum -y install flannel kubernetes-node
