Multi-Host Docker Network
How to get several servers running docker and the containers talking to one another on a unified bridge. Running Docker is becoming increasingly common; many guides are available online to get started and let you spawn containers on a box; may it be a Linux server, or even on your Mac with projects like boot2docker. Running on several boxes is another story… Several options: Run docker separately

GitHub - sdnhub/lorispack: Network Microsegmentation for Docker container deployments
Docker networking is fast evolving. There are many options today for using Linux bridge, port mapping, Open vSwitch for this purpose. See our presentation on the different options available, and especially how to network containers across multiple hosts. We found the need to have a comprehensive mechanism to network all applications across hosts with isolation through overlay networking. The loris

Hack for Docker's Network
12. â– ICC http://docs.docker.io/en/latest/use/networking/ The value of the Docker daemon's icc parameter determines whether containers can communicate with each other over the bridge network. + The default, -icc=true allows containers to communicate with each other. + -icc=false means containers are isolated from each other. Docker uses iptables under the hood to either accept or drop communicatio
