1. Contributing with Ceph and OpenStack Cinder on upstream Ceph day Arg Medallia 29-11-2017
2. whoiam • Sofia Enriquez • IRC: #enriquetaso (irc.freenode.org) • Twitter: @enriquetaso • Web: www.enriquetaso.com • Email: lsofia.enriquez@gmail.com
3. OUTLINE • Which OpenStack projects use Ceph. • Places to find inspiration and documentation. • Contributors workflow. • Basic configuration to setup an environment.
4. Integrating Ceph Storage with OpenStack Ceph can act as storage backend for: - OpenStack Block Storage (Cinder), - OpenStack Image service (Glance), - OpenStack File Share service (Manila). In addition, Ceph Storage can be a drop-in replacement for OpenStack Object Storage (Swift).
5. Where can I find inspiration?
6. Bugtracker
7. Superuser magazine http://superuser.openstack.org/articles/tag/ceph/
8. Get in touch with the community • Join the weekly IRC meetup. • Subscribe to the email-list. • Just join any IRC openstack channel.
9. Before start contributing...
10. Read the developer’s guide https://docs.openstack.org/infra/manual/developers.html
11. Cinder contribution workflow Local Environment Upstream code cinder / master cinder / master cinder / topic_branch git checkout -b topic_branch Gerrit (Review system) Review requirements: Core reviews: 2 (+2) y 0 (-2) Jenkins: +1 1. Fix chances 2. Run unit tests 3. git commit git commit --amend git clone Zuul (automated testing) devstack
12. Set Up a Cinder environment with ceph as storage backend
13. Vagrantfile example One way to deploy an Openstack developer environment is with virtualbox + vagrant: • <4Gb. • Be careful with the shell provisions.
14. DevStack is a series of extensible scripts used to quickly bring up a complete OpenStack environment based on the latest versions of everything from git master. It is used interactively as a development environment and as the basis for much of the OpenStack project’s functional testing. • Also a OpenStack project. • All-In-One Single Machine. • Devstack attempts to support Ubuntu 16.04/17.04, Fedora 24/25, CentOS/RHEL 7, as well as Debian and OpenSUSE. • If you do not have a preference, Ubuntu 16.04 is the most tested, and will probably go the smoothest.
15. Devstack configuration file: localrc or local.config Custom localrc to set Ceph as backend storage for Cinder and Glance. • I dont recommend to run `.stack.sh` without a local.conf or locarlrc. • Use devstack-plugin-ceph: avoid do all from scratch if you don’t know how to.
16. Work finished and unittest passed… ¯\_(ツ)_/¯
