What does Blazar do? • Reservation service • The project offers users a reservation for their future usage of cloud resources. The reservation ensures users can deploy as many resources on the cloud as they have reserved.
Project background ● Founded during the Icehouse release of OpenStack ○ contributions from Bull, Inria, Mirantis, Intel… ○ but inactive between Kilo and Newton ● Revived following the Barcelona Summit ● 10 contributors for latest release ● Not yet in the Big Tent
Use cases ● Chameleon project (http://www.chameleoncloud.org) ○ Large-scale testbed for computer science research ○ Blazar guarantees resource availability for experiments ● OPNFV Promise project (https://wiki.opnfv.org/display/promise/Promise) ○ Resource reservation and management project for quality of network services ○ Blazar guarantees resource availability for VNF deployments
New features & enhancements in Ocata HOST RESERVATION ➡ • Blazar users can reserve exclusive access to physical hosts • Instances launched on reserved hosts via hints provided to a Nova scheduler filter • Blazar manages a Nova host aggregate for each reservation FOLLOWING UP-TO-DATE OPENSTACK RELEASE ➡ • Switch from oslo-incubator to oslo libraries • Fix unit tests and Tempest tests • https://launchpad.net/blazar/0.x.0/0.2.0
How we revived Blazar (1/2) FIRST STEPS ➡ • Bootstrap the revival community with interested parties in Barcelona • Restart weekly IRC meetings • Fix the gate • Old oslo-incubator code referred to ssl.PROTOCOL_SSLv3 • Default gate job environment moved to ubuntu-xenial • SSLv3 was disabled in OpenSSL on Ubuntu due to POODLE • Get DevStack to install Blazar correctly • DevStack changes regularly, so old plugins can rely on deleted environment variables • Removed nova master tarball from test-requirements.txt which clashed with upper constraints
How we revived Blazar (2/2) ADAPT TO CURRENT OPENSTACK PATTERNS ➡ • Switch to oslo libraries • Remove libraries not supported by global requirements, enable project in OpenStack Proposal Bot • Use latest test environments (Ubuntu Xenial) • Use new tempest plugin style • Add release notes managed with reno FOCUS ON WHAT WORKS ➡ • Deprecated instance reservation for the Ocata release STILL TO DO… ➡ • Add Python 3 support and create OpenStackClient plugin • Support new API endpoint style (e.g. /identity) and have our own (/reservation?)
