30. Docker swarm 4 Docker Swarm is native clustering for Docker. 4 Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Flynn, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.

49. Notes at the end 4 don't use Docker as VM 4 build & production images 4 tag every image using in production (not just latest) 4 big difference between languages (NodeJS & Go) 4 don't use latest Docker versions in production 4 try use dockerlint for your Dockerfiles IPEX Meetup Brno, 9.3.2016 49
