[[email protected] master] etcdctl set/coreos.com/network/config ' {"Network": "10.1.0.0/16"} '

---then perform the (A-G) part of the NODE1,NODE2 separately---

Finally open the Kubernetes service:

[[email protected] master] nohup kube-apiserver--logtostderr=true \

--v=0--etcd_servers=http://0.0.0.0:2378 \

--insecure-bind-address=0.0.0.0 \

[[email protected] master] nohup kube-controller-manager--logtostderr=true--v=0--master=http://0.0.0.0:8080 > >/var/log/kubernetes/controller.log 2>&1 &

[[email protected] master] nohup kube-scheduler--logtostderr=true--v=0--master=http://0.0.0.0:8080 >>/var/log /kubernetes/scheduler.log 2>&1 &

To see if a node joins:

[[email protected] master] kubectl get nodes
