Mininet fork adding support for container-based (e.g. Docker) emulated hosts.

Containernet

Containernet: Mininet fork that allows to use Docker containers as hosts in emulated networks

This fork of Mininet allows to use Docker containers as Mininet hosts. This enables interesting functionalities to built networking/cloud testbeds. The integration is done by subclassing the original Host class.

Based on: Mininet 2.3.0d6

NFV multi-PoP Extension

There is an extension of Containernet called vim-emu which is a full-featured multi-PoP emulation platform for NFV scenarios that was developed as part of the SONATA-NFV project and is now hosted by the OpenSource MANO project.

Installation

Bare-metal installation

• Requires: Ubuntu Linux 16.04 LTS

  $ git clone https://github.com/ramonfontes/containernet.git
  $ cd containernet
  $ sudo util/install.sh -W

  Wait (and have a coffee) ...

Usage / Run

Start example topology with some empty Docker containers connected to the network.

• cd containernet
• run: sudo python examples/containernet_example.py
• use: containernet> d1 ifconfig to see config of container d1

Topology example

In your custom topology script you can add Docker hosts as follows:

info('*** Adding docker containers\n')
d1 = net.addDocker('d1', ip='10.0.0.251', dimage="ubuntu:trusty")
d2 = net.addDocker('d2', ip='10.0.0.252', dimage="ubuntu:trusty", cpu_period=50000, cpu_quota=25000)
d3 = net.addHost('d3', ip='11.0.0.253', cls=Docker, dimage="ubuntu:trusty", cpu_shares=20)
d4 = net.addDocker('d4', dimage="ubuntu:trusty", volumes=["/:/mnt/vol1:rw"])

Tests

There is a set of Containernet specific unit tests located in mininet/test/test_containernet.py. To run these, do:

• sudo py.test -v mininet/test/test_containernet.py
