How to Build and Develop Voltha

There are many ways to build and develop Voltha:

  • Use the provided Vagrant environment. This mode is by far the most reliable, and the only one officially supported.
  • Use your native MAC OS or Linux environments. These are not supported, although we provide guidance in a best effort manner and contributions/patches are graciously accepted from the community.

Build and Develop on the Vagrant Box

Prerequisites

  • Git client
  • Working installation of Vagrant

Build

git clone git@bitbucket.org:corddesign/voltha.git
cd voltha
make vagrant
vagrant ssh # the rest to be executed inside the vagrant VM
cd /voltha
make

The above has generated a new Docker image '''cord/voltha''' inside the VM:

docker images

Run in stand-alone (solo) mode

The simplest way to run the image (in the foreground):

docker run -ti cord/voltha

Building natively on MAC OS X

For advanced developers this may provide a more comfortable developer environment (e.g., by allowing IDE-assisted debugging), but setting it up can be a bit more challenging.

Prerequisites

  • git installed
  • Docker-for-Mac installed
  • Python 2.7
  • virtualenv
  • brew (or macports if you prefer)

Installing Voltha dependencies

The steps that may work (see list of workarounds in case it does not):

git clone git@bitbucket.org:corddesign/voltha.git
cd voltha
make venv

Potential issues and workaround:

  1. Missing virtualenv binary. Resolution: install virtualenv.

    brew install pyenv-virtualenv
    
  2. 'make venv' exits with error 'openssl/opensslv.h': file not found. Resolution: install openssl-dev and add a CFLAGS to make venv:

    brew install openssl
    

    Note the version that it installed. For example, '1.0.2h_1'. Rerun make venv as:

    env CFLAGS="-I /usr/local/Cellar/openssl/1.0.2h_1/include" make venv
    

Building Docker Images and Running Voltha

These steps are not different from the Vagrant path:

make

Then you shall be able to see the created image and run the container:

docker run -ti cord/voltha
