The document outlines the agenda for a meeting led by Victor Morales, focusing on the XCI project's goals, components, and CI/CD practices aimed at improving feature integration and feedback speed in OPNFV. Key components discussed include Bifrost and OpenStack-Ansible for provisioning and installation of cloud services, along with various scenario features supporting multiple Linux distributions. The proposal emphasizes continuous delivery, visibility, and reusability of upstream tooling to enhance platform reliability.
Validating latest changes with XCI
- 1. Validating latest changes with XCI Victor Morales Senior Cloud Engineer
- 2. Agenda • Problem statement • CI/CD principles & practices • Proposal • XCI definition and goals • Main Components • Workflow • Features
- 6. 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
- 7. 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
- 8. Proposal
- 9. 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
- 10. Main components
- 11. Bifrost • Standalone Ironic • Tool for provisioning virtual and bare metal machines • Ansible based • Supports multiple distros • Ubuntu • CentOS • OpenSUSE
- 12. OpenStack-Ansible • Tool for installing OpenStack • Containerized OpenStack services (LXC) • Ansible based. • Supports multiple distros • Ubuntu • CentOS
- 14. Features • Multiple Linux Distributions Support • Ubuntu • CentOS (In progress) • OpenSUSE
- 15. Features – part 2 • Multiple Scenarios • Kubernetes without SDN Controller (k8-nosdn-nofeature) • OpenStack without SDN Controller (os-nosdn-nofeature) • OpenStack with OpenDaylight Controller (os-odl-nofeature)
