Hi,

Which options would be recommended to run a High Available (HA) kubernetes cluster using Atomic?

We are considering two different tracks: 1) the kubernetes documented approach with an external load balancer and an etcd CAS to decide on the node acting as a Kubernetes master 2) A pacemaker based approach (corosync pcs) using a virtual IP where pacemeker is deciding which node is acting as a master

Any ideas? Recommendations? Red Hat supported choices?

The documented approach for kuberenetes is a proof of concept. If you look at the doc you'll see:

In the future, we expect to more tightly integrate this lease-locking into the scheduler and controller-manager binaries directly, as described in the high availability design proposal

I don't know that anyone has a recommended, production level HA approach for k8s at this point. Love to see otherwise though.
