I'm trying to setup Kube's cluster with 2 master node 10.0.11.108 and 10.0.11.97 (Ubuntu) with config "ai ai" in cluster/ubuntu/config-default.sh file.

When I run 

KUBERNETES_PROVIDER=ubuntu ./kube-up.sh,

it run deployscript in node 10.0.11.97 twice. And become error:

[sudo] password to copy files and start node: cp: cannot create regular file ‘/opt/bin/etcd’: Text file busy cp: cannot create regular file ‘/opt/bin/kube-apiserver’: Text file busy cp: cannot create regular file ‘/opt/bin/kube-controller-manager’: Text file busy cp: cannot create regular file ‘/opt/bin/kube-scheduler’: Text file busy start: Job is already running: etcd

I don't believe kube-up supports multi-master deployments. you'll have to do this on your own. Provision 2 masters with the right binaries, provision a loadbalancer in front of them both, and give the ip of the loadbalancer to your kubelets. - Prashanth B
@PrashanthB yep. i want to deploy HA kubernetes cluster. I can't find any guild except: kubernetes.io/docs/admin/high-availability but i dont understand it. hic, then i think i can start with deploy multi master node in 1 cluster. :(( - luanbuingoc

I setup Kube's cluster with 1 master, run twice, encounter the same error message, I modified utuntu/util.sh, and get 'Cluster validation succeeded'.

First add -f for all cp commands, like this: cp ~/kube/default/* /etc/default/ ===> cp -f ~/kube/default/* /etc/default/

Then rerun ./kube-up.sh, you will encounter "start: Job is already running: etcd"

Then modified utuntu/util.sh, modify all 'service XXX start' to 'service XXX restart' , and run kube-up.sh, You'll get the success message.
