Please check the [Installation](https://github.com/sonata-nfv/son-emu#installation) section for more details about the installation of son-emu. + +### Dependencies + +Son-emu requires the latest version of [Containernet](https://github.com/mpeuster/containernet) to be installed on the system. + +Despite of this son-emu has the following dependencies: + +* [argparse](https://pypi.python.org/pypi/argparse) >= 1.4.0 (Python software foundation License) +* [docker-py](https://pypi.python.org/pypi/docker-py) == 1.7.1(Apache 2.0) +* [Flask](https://pypi.python.org/pypi/Flask) >= 0.11 (BSD) +* [flask_restful](https://pypi.python.org/pypi/Flask-RESTful) >= 0.3 (BSD) +* [networkx](https://pypi.python.org/pypi/networkx/) >= 1.11 (BSD) +* [oslo.config](http://docs.openstack.org/developer/oslo.config/) >= 3.9.0 (Apache 2.0) +* [prometheus_client](https://pypi.python.org/pypi/prometheus_client) >= 0.0.13 (Apache 2.0) +* [pyaml](https://pypi.python.org/pypi/pyaml) >=15.8.2 (WTFPL) +* [pytest-runner](https://pypi.python.org/pypi/pytest-runner) >= 2.8 (MIT) +* [pytest](https://pypi.python.org/pypi/pytest) >= 2.9 (MIT) +* [requests](https://pypi.python.org/pypi/requests) >= 2.10 (Apache 2.0) +* [ryu](https://pypi.python.org/pypi/ryu/4.4) >= 4.4 (Apache 2.0) +* [six](https://pypi.python.org/pypi/six/) >=1.9 (MIT) +* [tabulate](https://pypi.python.org/pypi/tabulate) >= 0.7.5 (public domain) +* [urllib3](https://pypi.python.org/pypi/urllib3) >= 1.15 (MIT) +* [zerorpc](http://www.zerorpc.io) >= 0.5.2 (MIT) + +### Contributing +Contributing to the son-emu is really easy. You must: + +1. Clone [this repository](http://github.com/sonata-nfv/son-emu); +2. Work on your proposed changes, preferably through submiting [issues](https://github.com/sonata-nfv/son-emu/issues); +3. Submit a Pull Request; +4. Follow/answer related [issues](https://github.com/sonata-nfv/son-emu/issues) (see Feedback-Chanel, below). + +## Installation +There are two ways to install and use son-emu. The simple one is to use Vagrant to create a VirtualBox-based VM on your machine that contains the pre-installed and configured emulator. The more complicated installation requires a freshly installed Ubuntu 16.04 LTS and is done by a ansible playbook. + +### Vagrant Installation + +* Request VirtualBox and Vagrant to be installed on the system. +* `git clone https://github.com/sonata-nfv/son-emu.git` +* `cd ~/son-emu` +* `vagrant up` +* `vagrant ssh` to enter the new VM in which the emulator is installed. + +Follow the MOTD in the VM to run the example topology and the dummy-gatekeeper. The dummy-gatekeeper's default port 5000 is forwarded to the host machine and can be accessed from it by using, e.g., curl http://127.0.0.1:5000/packages. + +### Ansible Installation + +* Requires: Ubuntu 16.04 LTS +* `sudo apt-get install ansible git aptitude` +* `sudo vim /etc/ansible/hosts` +* Add: `localhost ansible_connection=local` + +#### 1. Containernet + +* `cd` +* `git clone https://github.com/containernet/containernet.git` +* `cd ~/containernet/ansible` +* `sudo ansible-playbook install.yml` +* Wait (and have a coffee) ... + +#### 2. Emulator + +* `cd` +* `git clone https://github.com/sonata-nfv/son-emu.git` +* `cd ~/son-emu/ansible` +* `sudo ansible-playbook install.yml` + +## Usage + +### Examples + +This simple example shows how to start the emulator with a simple topology (terminal 1) and how to start (terminal 2) some empty VNF containers in the emulated datacenters (PoPs) by using the son-emu-cli. + +* First terminal (start the emulation platform): + * `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: + * `containernet> vnf1 ifconfig` + * `containernet> vnf1 ping -c 2 vnf2` + + +### Further Documentation +* [Full CLI command documentation](https://github.com/sonata-nfv/son-emu/wiki/CLI-Command-Overview) +* [Requirements for Docker containers executed by the emulator](https://github.com/sonata-nfv/son-emu/wiki/Container-Requirements) +* [REST API](https://github.com/sonata-nfv/son-emu/wiki/REST-API-command-overview) + +## License + +Son-emu is published under Apache 2.0 license.
