Multi-Host Networking using Consul, Docker Libnetwork and Nuage SDN

First time I’ve heard about Consul. Anyway. I think it’s a nice way to try multi-host on a overlay network. Very clean and simple. Waiting to see the same for Kubernetes. Definitely I will try this. Thanks Mostafa again.

Overview

The Nuage libnetwork plugin allows users to create new networks of type Nuage. Nuage libnetwork plugin runs on every docker host. Each Docker host, whether bare-metal or virtual, also has the VSP’s Virtual Routing and Switching (VRS) component installed on it. VRS, a software agent, is the Nuage user space component of standard Open vSwitch (OVS). It is responsible for forwarding traffic from the containers, performing the VXLAN encapsulation of layer-2 packets, and enforcing security policies. When creating a Docker container, the user can specify what Zone or Policy Group it belongs to. All endpoints in a given Zone adhere to the same set of security policies. Nuage libnetwork plugin supports built in IPAM driver where the IP address management is done by VSP.

The libnetwork plugin supports both local and global scope networks. The scope defines if your network is going to propagate to all the nodes as part of your cluster.
