This repository contains scripts to help you set up a simple
namespace-based testbed, with networking between the namespaces.
Optionally, you can start docker containers in the namespaces.

If we're using docker, the containers don't need to do much in order
to demonstrate basic networking (you can change this to suit your
needs), so we're just going to run the command

    tail -f /etc/issue

This will never exit, while it waits for more output to be appended
to the file.

To start the testbed, run

    ./start_testbed.py [-f <config file>]

To stop the testbed, run

    ./stop_testbed.py [-f <config file>]

In both cases, if the config file isn't specified, it will use
example.yml in the current directory.
