This month’s OSF newsletter features the Certified OpenStack Administrator (COA) exam, projects update, upcoming events and more.


The updated OpenStack Certified OpenStack Administrator (COA) exam became available in October 2019, and we have seen a resurgence in interest by both the global community and our training partners. Thousands of Stackers have demonstrated their skills and proven their expertise, helping organizations identify top talent in the industry. The COA exam remains a critical and respected certification for anyone working on OpenStack.

New to OpenStack? Has your certification expired? Do you want to prove your OpenStack skills? Take a look at the OpenStack Docs, then head over to the OpenStack Training Marketplace and find one of our qualified Training Partners. They will help guide you through all of the critical pieces you need to succeed in taking the COA. The current exam is based on OpenStack Rocky and this is an opportunity to not only get a certification, but also get familiar with one of the more recent OpenStack releases.

The exam itself covers all of the core compute, storage, image, and networking services necessary to run OpenStack. To kickstart your preparation for the COA exam, we are offering a 20% discount when you purchase through the OpenStack website. Use code COARECERT2020 through February 29, 2020.

Once you’ve completed the exam, it’s time to get involved with the OpenStack Community:

  • Go to to learn how you can be a part of the community through code contribution, user groups, or even becoming a mentor for new users.
  • Meet other community members at one of our upcoming events. OpenDev+PTG in Vancouver and the Open Infrastructure Summit in Berlin provide an opportunity to share thoughts about the software, swap war stories, and generally get to know folks working on OpenStack.

The OpenStack Foundation would like to thank Mirantis for administering the exam and the dozens of global training partners who are supporting the next wave of OpenStack talent.

Airship: Elevate your infrastructure

  • Congrats to the newest members of the Airship Technical and Working Committees, Andrew Leasck (TC) and Ian Pittwood (WC)!
  • Airship Blog Series 6 – Armada Growing Pains is out! Armada provides a way to synchronize a Helm (Tiller) target with an operator’s intended state, consisting of several charts, dependencies, tests, and overrides using a single file or directory with a collection of Armada declarations. This allows operators to define many charts, potentially with different namespaces for those releases, and their overrides in a central place. With a single command, they can deploy and/or upgrade all of them where applicable.
  • Catch up on the latest Airship news, including 2.0 plans on the blog.

OpenStack: Open source software for creating private and public clouds

  • Brian Rosmaita reported an issue that, in rare conditions, may cause data loss in Cinder volumes for the OpenStack Train release. Train deployments are advised to deploy the described workaround to avoid any issue.

  • Every cycle, our community sets common goals for the next OpenStack release. Ghanshyam Mann just started the process for the Victoria development cycle, which will start after Ussuri is released in May. We are interested in goals that have user-visible impact and make OpenStack easier to operate. If you are interested in proposing a goal, please write down your idea on the Victoria goals etherpad!
