Registrations are running via EventBrite. Click Here to Register Now. OpenNebulaConf2015 registration includes a free pass to CentOS Dojo, but you will have to register in the previous link.
The CentOS Dojo’s are a one day event, organised around the world, that bring together people from the CentOS Communities to talk about systems administration, best practises in linux centric activities and emerging technologies of note. The emphasis is to find local speakers and tutors to come together and talk about things that they care about most, and to share stories from their experiences working with CentOS in various scenarios.
Registrations close on the 15th Oct 2015 and everyone registering gets an exclusive CentOS Dojo T-shirt.
