kops cluster management

export NAME=myfirstcluster.k8s.local
export KOPS_STATE_STORE=s3://kubernetesaws-example-com-state-store

$ ssh-keygen -t rsa -f /home/vagrant/.ssh/id_rsa -q -P ""

$ kops create cluster --zones us-west-2a ${NAME}

$ kops create secret --name myfirstcluster.k8s.local sshpublickey admin -i ~/.ssh/id_rsa.pub

$ kops update cluster ${NAME} --yes

Cluster is starting.  It should be ready in a few minutes.

Suggestions:
 * validate cluster: kops validate cluster
 * list nodes: kubectl get nodes --show-labels
 * ssh to the master: ssh -i ~/.ssh/id_rsa admin@api.myfirstcluster.k8s.local
 * the admin user is specific to Debian. If not using Debian please use the appropriate user based on your OS.
 * read about installing addons at: https://github.com/kubernetes/kops/blob/master/docs/addons.md.
