Did you try 0.9.3 under k8s? We did some work specifically targeting k8s by enabling pods with servers to get restarted with new IPs, even all of the servers at once. That required Consul to be configured with -raft-protocol=3 to benefit in 0.9.3. That's the default now in 1.0, so both of those versions should be much more stable under k8s.

I'd be curious if you ran into other kinds of issues on k8s and if you tried 0.9.3 with the required raft protocol version set before you gave up.
