Kubectl get nodes - Issue

[harshapic]

https://github.com/kubernetes/frakti/blob/master/docs/deploy.md

followed above steps to deploy frakti,hyperd, kubernetes on vmware-fusion (ubuntu-xenial), with 1master and 2 worker node setup.
workers got successfully registered to master but when i do "kubectl get nodes", its only displays master node.

Same setup if i do only with docker runtime it shows all nodes if i do "kubectl get nodes" (for this i followed this setup: https://blog.microideation.com/2017/03/06/setting-up-kubernetes-cluster-for-container-orchestration/ ).

I am not getting what i am doing wrong in frakti deployment steps

kubeadm init --pod-network-cidr 10.244.0.0/16 --kubernetes-version v1.7.0-alpha.4
(earlier i had same hostname for all 3 nodes(1master+2worker nodes) now i changed to different names -- might be this is causing issue i am not sure)
instead of kubernetes version latest which is 1.8(alpha) or 1.6.6(stable) its not working.
It worked with v1.7.0-alpha.4 kubernetes version.

@harshapic Thanks for reporting the problem. Tried both latest and stable kubernetes version:

• stable version (v1.6.6) works properly according to the guide
• latest version (v1.8-alpha) couldn't join node because of certificate not approving automatically (refer here).

However, the certificate could be approved manually by running kubectl certificate approve <csr-name> (<csr-name> could be found by kubectl get csr) command on the master node.

Thanks it helped...Now it is showing fine.... My another issue was previous my worker node's hostname all were same as master it is another issue. Now i changed my hostname for all machines. Now its perfect. Exactly followed steps in deployment doc and everything worked fine
