The document outlines the progress and challenges faced by the OPFNV project in deploying OpenStack, highlighting achievements such as multiple releases and numerous deployments. It identifies issues like slow integration cycles and limited developer resources, while proposing improvements through enhanced automation and development practices. The status of tools like Bifrost and OpenStack Ansible is discussed, emphasizing their role in streamlining the integration process for future releases.
Being Brave: Deploying OpenStack from Master
- 2. Being Brave: Deploying OpenStack from Master Fatih Degirmenci, Ericsson Yolanda Robla Mota, RedHat Markos Chandras, SUSE
- 3. • Story so far • How can we improve? • Bifrost and OpenStack Ansible • Current status & Next steps
- 4. Our story so far • What has OPNFV achieved? • 4 releases • 10s of scenarios • 100s of developers • 1000s of deployments • How did OPNFV achieve this? • Put good (enough) way of working for integration and testing • Always regarded automation as crucial • Established good (enough) CI pipeline
- 5. What are our pains? • Late integration • It takes months for a feature/fix to be available to OPNFV • Slow feedback • It takes months to know if the feature/fix works • Lack of visibility • It is not easy to track the progress of anything • High demand on limited no of people • new OpenStack release -> installer uplift -> feature integration • Too fragmented • Too many ways to do same thing, differently
- 6. How have we been working? Project Team OPNFV Gerrit OPNFV CI/Test OPNFV Release Upstream Gerrit Upstream CI/Test Upstream Release Requirement Patch Test Release Downstream Release Test Test Document • Long development cycle • Downstream will delay to next release • Slow feedback, > 5 months • OPNFV specific issues cannot be tested/detected in time
- 7. How can we improve? • Work against trunk • Do things when things happen • Provide means for developers to develop • Use upstream tooling
- 9. Bifrost • What is it? • Standalone Ironic • Tool for provisioning virtual and bare metal machines • Ansible based • Supports Ubuntu, Centos, and SUSE • Easy to use – create inventory, install bifrost, enroll and deploy machines! • Current Status • Rock-solid! • OPNFV runs 3rd Party CI for all the patches! • Used by OPNFV XCI
- 10. Bifrost – Node Enrollment
- 11. Bifrost – Node Deployment
- 12. OpenStack Ansible • What is it? • Tool for installing OpenStack • Containerized (lxc) OpenStack services (or install them on baremetal too) • Ansible based • Easy integration – write your own role • Ability to deploy using patches • Supports Ubuntu, and Centos • Current Status • Possibility to be used for OpenStack gating • SUSE support is on its way
- 14. What we will achieve? • early integration – work with master branch (weekly) • faster feedback – feedback per patchset or on a daily basis • alignment and reuse – use of upstream tooling • better visibility – discover bugs in OPNFV environment and fix them
- 15. Where are we now and what is next? • We have the first scenario – os-nosdn-nofeature-ha from master! • Virtual machines • Bare metal nodes • We have the developer sandbox available for quite some time • 4 flavors; all in one, mini, noha, ha • OpenDaylight, Tacker, OVS integration work is on its way

Editor's Notes
- #6: Backporting changes are possible for certain projects and in some cases but it is not always possible. It also takes extra effort and time to do that.
