Hi, During the last OpenStack PTG, I announced in the Cinder room the development of cinderlib, and explained how this library allowed any Python application to use Cinder storage drivers (there are over 80) without running any services.
This takes the standalone effort one step further. Now you don't need to run any Cinder services (API, Scheduler, Volume), RabbitMQ, or even a DB, to manage and attach volumes and snapshots. Even though we don't need a DB we still need to persist the metadata, but the library supports JSON serialization so we can save it wherever we want. I'm also finishing a metadata persistence plugin mechanism to allow external plugins for different storage solutions (DB, K8s CRDs, Key-Value systems...). This library opens a broad range of possibilities for the Cinder drivers, and I have explored a couple of them: Using it from Ansible and in containers with CSI driver that includes the latest features including snapshots that were introduced last week. The projects' documentation is lacking, but I've written a couple of blog posts with a brief introduction to these POCs for anybody that is interested: - Cinderlib: https://gorka.eguileor.com/cinderlib - Ansible storage role: https://gorka.eguileor.com/ansible-role-storage - Cinderlib-CSI: https://gorka.eguileor.com/cinderlib-csi And the repositories can be found in GitHub: - Cinderlib: https://github.com/akrog/cinderlib - Ansible storage role: https://github.com/akrog/ansible-role-storage - Cinderlib-CSI:https://github.com/akrog/cinderlib-csi Cheers, Gorka. __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
