I don't know the above poster but we run over 4500 docker containers on AWS distributed using kubernetes. Docker has indeed caused us a problem or two in the past, but actually it's largely smooth sailing and most of our problems are with the app layers and both docker and kubernetes have largely made our lives much easier. A quick skim would suggests that sits on about 8TB of Ram and 1000vCPUs spread over 100 machines. It's not the biggest stack in the world, but it's doing a good job as our little internal PaaS. We have some non-aws versions too, but I don't have metrics on those right now.
