Following are the steps I followed.

1. Installed and configured etcd, kube apiserver, kube controller manager , kube-scheduler, flannel on master.
2. List item kubectl get nodes doesnt display any nodes initially.

3. Installed and configured flannel network, kubernetes, docker on node.When node starts up and trying to register with api server, it gives this error in journalctl -xe

   Attempting to register node 192.168.6.103 E1222 02:20:03.487534 2030 kubelet.go:1222] Unable to register node "192.168.6.103" with API server: the body of the request was in an unknown format - accepted media ty E1222 02:20:03.490982 2030 event.go:198] Server rejected event ' &api.Event{TypeMeta:unversioned.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:api.ObjectMeta{Name:"192.168 E1222 02:20:03.493741 2030 event.go:198] Server rejected event '&api.Event{TypeMeta:unversioned.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:api.ObjectMeta{Name:"192.168

Following are the version installed on the node. I guess it is an issue with the node.

Docker client version - 1.10.3 API server 1.22 Docker server version - 1.10.3 API server 1.22

kubectl version gave an error

The connection to the server localhost:8080 was refused - did you specify the right host or port?

I had done this

$ kubectl config set-cluster demo-cluster --server=http://master.example.com:8080
$ kubectl config set-context demo-system --cluster=demo-cluster
$ kubectl config use-context demo-system

Then the version is displayed as

Client version,. Major 1 Minor 3 Server version Major 1 Minor 2

Anything I am doing wrong? Any suggestions would be very helpful.

Thanks
