Bangalore CentOS Dojo, 2014

The first CentOS Dojo in India took place in Bangalore on 15th November(Saturday) 2014 at Red Hat Bangalore office. Red Hat had sponsored the event.

I was  a co-organizer of the Dojo along with Dominic and Karanbir Singh.  Around 90 people RSVPed  for the event but around 40 (mostly system administrators and new users) attended the event.

The First talk was by Aditya Patawari on “An introduction to Docker and Project Atomic”. The talk included a demo and introduced audience to docker and Atomic host. Most of the attendees had questions on docker as they had used or have heard about it. There were some questions about differences between CoreOS and Project Atomic. The slides are available at Overall this talk gave fair idea about Docker and Atomic project.

Second talk was “Be Secure with SELinux Gyan” by Rejy M Cyriac. This session about troubleshooting SELinux issues and introduction to creating custom SELinux policy modules.  Rejy made the talk interesting by distributing SELinux stickers to attendees who asked interesting questions or answered questions. Slides can be found here.

After these two talks we took a lunch break for around 1 hour.  During the lunch break we distributed the CentOS t shirts and got a chance to socialize with the attendees.

The first session post launch was “Scale out storage on CentOS using GlusterFS” by Raghavendra Talur. The talk introduced the audience to GlusterFS, important high level concepts and a demo was shown using packages from CentOS storage SIG. Slides can be found at slideshare.

The next session was “Network Debugging” by Jijesh Kalliyat. This talk covered all most all basic concepts/fundamental, network Diagnostic tools required to troubleshoot a network issue. Also  it included a demo of use Wireshark and Tcpdump to debug network issues. Slides are available here.

Before the next talk, we took break for some time and clicked some group pictures of all present for the Dojo.

The last session was on “Systemd on CentOS” by Saifi Khan. The talk covered a lot of areas e.g. comparison between SysVinit and systemd,  Concurrency at scale, how systemd is more scalable than other available init systems, some similarity of design principles with CoreOS and how it is suited better for Linux container technology. Saifi also talked about how systemd has saved his system from being unusable.  His liking for systemd was quite evident from the talk and enthusiasm.

Overall it was an awesome experience participating in the Dojo as it covered wide variety of topics which are important for deploying CentOS for various purposes.
