We're using Puppet to deploy our kubernetes cluster on bare-metal as well as on AWS.

Achieving HA isn't necessarily complicated. Etcd supports clustering by default and the master components have master election builtin.

We also use haproxy locally on every machine to loadbalance between the different api servers. So we don't need a central LB.

Setting up HA was only a small part of our overall effort. Making things robust and figuring out the small details are a lot harder.
