Jeremy Eder from Red Hat on Docker performance testing

Red Hat Inc - Annex

After our combined kick-off Meetup with Triangle Devops (http://www.meetup.com/Triangle-DevOps) it became clear that there was a substantial gap between people's overall understanding of Docker. To try to rectify this, we're going to split this next meetup into two sections. The first will be a fulfillment of initiative raised by Andrew Spyker on our Meetup page suggesting a Docker 101 type session to help people who are new to Docker get some hands on experience with it, doing tasks like:-

• setup VBox/Boot2Docker

• get Docker installed

• run a basic bash container

• modify the basic container

• commit/push the resulting image

• run a few containers and link them, etc

This session will run from 5:30'ish to 7pm and will be lead by Aaron Huslage with the assistance of a few volunteers to help people get started.

The second section (starting at 7pm) is a talk from Jeremy Eder from Red Hat about the performance testing he and his team have been doing over the last 7 months. Jeremy is a Principal Software Engineer and has been the Network Performance Lead at Red Hat for just under 2 years.

Since the early part of January, the Performance Engineering Group at Red Hat has run huge amounts of microbenchmarks, benchmarks and application workloads in Docker containers. The output of that effort has been a steady stream of lessons learned and advice/guidance given to our product architects and developers. How dense can we go ? How fast can it go ? Are these defaults “sane” ? What NOT to do…etc.

Disclaimer: as anyone who has worked with Docker knows, it’s a project under heavy development. I mention that because this talk includes code snippets and observations that are tied to specific experiments and Docker/kernel versions. YMMV, the answer of course is “it depends”, and so on.

Logistics:

Parking is technically not free until 7pm, however from what I understand if people drive in at 6-6:30, and leave after 7, the gates will be up. The parking deck has two entrances. One is located on Wilmington Street and the other on Blount Street (attaching images for ease). The address for the Parking deck at Red Hat Tower is 429 S. Wilmington Street, Raleigh, NC 27601. More information about the parking deck attached to Red Hat tower:

The Annex is not located in Red Hat Tower; it's a very brief 1-2 minute walk from the lobby of Red Hat Tower. To access the Annex, visitors have three routes they could follow: 1. (Best Option) Elevator on the NE Side of City Center Parking Deck will take them directly to the door of Red Hat's Annex. Upon exiting the elevator, turn right and the door is right there.

2. Elevator on the NW side of the City Center Parking deck will take attendees to Red Hat's main lobby. Security personnel in Red Hat Tower's main lobby will not be able to escort attendees to the entrance of the Annex during this meetup. Attendees should exit the lobby via the main doors, and turn right on Davie. The Annex will be located down a hallway between the Oak City Meatball Shoppe and cala vela.

3. Elevator on the SW side of City Center Parking Deck will drops attendees off at the corner of Cabarrus & Wilmington. Head north on Wilmington (follow the direction of car traffic) and take a right on E. Davie Street. Pass bu-ku & Red Hat Tower's lobby on your right. The Annex will be located down a hallway between the Oak City Meatball Shoppe and cala vela.

Sorry for the wait, but there is now a blog post up for Jeremy Eder's presentation with a link to the YouTube video:
http://developerblog.redhat.com/2014/08/19/performance-analysis-docker-red-hat-enterprise-linux-7 . The blog post has links to the Dockerfiles and GitHub repos for everything that was talked about during the presentation as well general follow up commentary.

I'm sorry for the 4 minute window of silence from 48:42 to 52:38. The batteries on the microphone went out and we had to scramble a little to get another working microphone up and working.

Thanks everyone!

Secondly, because we were lacking a few of our organizers, we were not able to do an in-person raffle of James Turnbull's "The Docker Book", so I took the manifest of people who RSVP'd and attended, removed the organizers and speakers, and imported the list into LibreOffice. I then used and old script (1) that I thought I'd never look at again to pull a random number "34" and matched that to the row and...Congratulations to Olaf Luetkehoelter, I'll reach out to you to get your email so James can send you the book.

Thanks to everyone that attended and I hope to see you all next time!

First off, thanks to Aaron and Jeremy for volunteering to present at our inaugural DockerRaleigh Meetup. I hope everyone got valuable information out of the talks and I'm excited to see so much interest in our area around Docker. I'll be working over the weekend on getting the video of the talk edited and processed so we can post it for everyone to view.

To Penny and anyone else that had to pay for parking. I'm very sorry that we gave misinformation, I will certainly update Red Hat's internal documentation so I don't make that mistake again. We were presenting in our new Annex space, that is unfamiliar to even the people that work at Red Hat, so I apologize again for any confusion that arose and I promise that we will make steps to ensure a smoother experience moving forward.

for future meetings, the parking is definitely not free until 6:46pm, and they man the gates to get every last penny from those who park before 6:46 until 10pm

Sitting in Dallas. Sorry I missed it. How did it go?

Thanks for feedback, I think the main idea w/ the earlier time was that there would be alot of folks using Docker for the first time and we did not want the 101 to cut into the presentation time. Going forward they can be split into 2 RSVPs (meetings) like you mention to avoid the confusion.

^^ agreeing with Magnus here. 5:45pm isn't very feasible for us folks that work in Durham. I'm going to try to make both since they're both important to me. :)

For the organizers... if the meeting is split into discrete pieces, in the future it might be useful to set those up as different events on the same day. The setup for this meeting was confusing, the details about it being multiple sessions was buried pretty far down. For the average ADHD reader, we just see 5:45 and click "Decline".

I can't make it tonight, I'll definitely be interested in the next meetup. I

I just realized that I completely forgot to mention that Red Hat will be providing Pizza and Refreshments for the Meetup.

Also, I'd like to thank Jon Baer for reaching out to James Turnbull who has now kindly agreed to provide an E-Book copy of "The Docker Book" http://www.dockerbook.com that we will be raffling off during the meetup.

Looking forward to seeing everyone tomorrow night!
Chris

This would have been fantastic - unfortunately I'm out of town next week. :-(

I would love to attend but already have my Raleigh VMUG, that I am the leader of, scheduled that night.

The talk starts at 7; read the description. :-)

I'd love to go but the start time is unusually early. Won't be able to get there from downtown Durham in time. :(
