Open Platform for Network Functions Virtualization (OPNFV) is collaborative open source platform which facilitates the development and evolution of various open source ecosystems through system level integration, deployment and testing. Cross Community Continuous Integration (XCI) is an OPNFV project that regularly integrates the latest from each supported branch of select upstream projects. In this session, I’m going to give an overview of the XCI project, how this project meet DevOps principles, explain its general workflow and share some challenges of consuming rapidly evolving open source projects.

Validating latest changes with XCI

  1. 1. Validating latest changes with XCI Victor Morales Senior Cloud Engineer
  2. 2. Agenda • Problem statement • CI/CD principles & practices • Proposal • XCI definition and goals • Main Components • Workflow • Features
  3. 3. OPNFV - Problem statement • Late integration – Takes months for a feature/fix to be available • Slow feedback – Takes months to know if a feature/fix works • Lack of visibility – Not easy to see the current state • Too fragmented – Many ways to do the same thing
  4. 4. CI/CD Principles & Practices • Fail fast, Fix fast • Always have a working software • Small and frequent commits • Reduce the complexity • Test early and often • Avoid surprises
  5. 5. Proposal
  6. 6. Cross Community (XCI) • It’s an additional OPNFV service that enables • Early integration – Works with master • Faster and tailored feedback • Reuse – Use of upstream tooling • Better visibility. • It aims to bring Continuous Delivery to OPNFV • Ensure composed platforms always work
  7. 7. Main components
  8. 8. Bifrost • Standalone Ironic • Tool for provisioning virtual and bare metal machines • Ansible based • Supports multiple distros • Ubuntu • CentOS • OpenSUSE
