This event is a development-oriented Hackfest in the form of several self-contained challenges such as bug fixes, developing small features, writing unit tests, or automating end-to-end tests exercising some use case. Key members of the OSM community will mentor challenges.

The Hackfest will start on Monday, 12 June, and finish on Friday, 16 June. On Monday, some theory sessions will be provided, followed by a description of the different challenges to be completed throughout the week. Participants will select a challenge to work on individually or in pairs.

During the week, participants will code autonomously (individually or in pairs) to solve their challenges. Daily sessions will be scheduled with the mentors so that participants can ask questions and solve blocking points.

On Friday, participants will share their achievements and lessons learned with the OSM community.

All active participants will receive a Certificate of Participation. Certificates of Excellence will be awarded to all those participants that complete their challenge.

This event will be an opportunity for participants:

  • Understanding the role of NFV Orchestration and OSM
  • Understanding OSM architecture and relationship with ETSI NFV Specifications
  • Getting familiar with OSM installation
  • Understanding OSM development workflow, practices, and tools: Git, Tox, Gerrit, Jenkins...
  • Understanding how to work in an open source project: contributing code, code reviews, automated testing...
  • Developing a first-hand experience with code development in OSM
  • Getting to meet and interact with crucial OSM community members.

Who should attend

  • This Hackfest is dedicated to software developers willing to gain first-hand experience contributing to Open Source MANO (ETSI OSM).

How to get ready


  • Registration is mandatory!

  • Participants are expected to have previous knowledge of Python.
    • Experience with Git, Docker, Linux, Kubernetes, Openstack, and the Robot Framework for testing, will be a plus.
  • Participants will need their laptop to develop, and a remote lab environment will be provided for testing. There are several options:
    • Recommended: Ubuntu 22.04
    • Other options:
      • Windows10 or higher
      • Other Linux OS, as long as they can meet the requirements below in terms of SW installation.
  • Optionally, if they want to install OSM in their laptop, the only recommended setup is a computer with Ubuntu 22.04 and the following HW requirements:
    • 4 CPUs;
    • 12 GB of RAM;
    • 120 GB of disk free space.
