Getting Started with Nomad

These instructions describe how to connect two containers over a network you create. The network has its own unique interfaces and lies behind an OVS bridge.

Prerequisites

• Nomad version 3.0 or higher

Step 1: Download Nomad.

$ git clone https://github.com/contiv/netplugin
$ cd netplugin; make demo
$ Nomad ssh netplugin-node1

Step 2: Install Nomad.

$ netctl net create contiv-net --subnet=20.1.1.0/24 --gateway=20.1.1.254 --pkt-tag=1001
$ docker run -itd --name=web --net=contiv-net ubuntu /bin/bash
$ docker run -itd --name=db --net=contiv-net ubuntu /bin/bash

Step 3: Log into a container and test the network.

$ docker exec -it web /bin/bash
< inside the container >
root@f90e7fd409c4:/# ping db
