Installation

Automatic installation is provide through Ansible playbooks.

  • Requires: Ubuntu 14.04 LTS
  • sudo apt-get install ansible git
  • sudo vim /etc/ansible/hosts
  • Add: localhost ansible_connection=local

1. Dockernet

  • cd
  • git clone -b dockernet-sonata https://github.com/mpeuster/dockernet.git
  • cd ~/dockernet/ansible
  • sudo ansible-playbook install.yml
  • Wait (and have a coffee) ...

2. Emulator

  • Fork the repository.
  • cd
  • git clone https://github.com/<user>/son-emu.git
  • cd ~/son-emu/ansible
  • sudo ansible-playbook install.yml

Run

In the ~/son-emu directory:

  • During development:
  • python setup.py develop
  • Otherwise, for a classic installation:
  • python setup.py install
  • First terminal:
  • sudo python src/emuvim/examples/simple_topology.py
  • Second terminal:
  • son-emu-cli compute start -d datacenter1 -n vnf1
  • son-emu-cli compute start -d datacenter1 -n vnf2
  • son-emu-cli compute list
  • First terminal:
  • dockernet> vnf1 ping -c 2 vnf2
  • Second terminal:
  • son-emu-cli monitor get_rate -vnf vnf1

Run Unit Tests

  • cd ~/son-emu
  • sudo py.test -v src/emuvim (equivalent to python setup.py test -v --addopts 'src/emuvim' but with direct access to the commandline arguments)
