Relaunching crashed processes is the visible part of HA and yes, Kubernetes and comparable systems do this well. I don't have direct experience with building HA data systems, but some other teams at my employers (Pivotal) do. We ship some of these as BOSH releases intended to allow service injection into Cloud Foundry (and pretty soon OpenShift and Kubernetes too[0]). For the purposes of what you describe, BOSH and k8s are comparable. Given that we have multiple teams that work continuously on building fully-packaged, fully automated HA data systems, I suspect that this stuff is harder than it looks.
