Duh, that's a nice list of references. I'll try to get trough the documentations and tutorial. It seems to solve a lot of troubles when we (normal people) have to deal when deploying docker container (in aws for example). Among others service discovery and health of nodes.
Otherwise, there's a list at http://kubernetes.io/community/, including: New York Times, eBay, Wikimedia Foundation, Box, Soundcloud, Viacom, and Goldman Sachs, to name a few.
