Kubecon 2018 Seattle was a great success

We had a great week at kubecon and I’ve finally had a chance to catch up on work and assess what we learned. First and foremost, the Kubernetes community is vibrant and growing. We had hundreds of wonderful conversations with folks at varying stages in their container adoption journey and learned a great deal from them about what works and what’s still difficult.

Attendance was way up

I believe the official attendance numbers roughly doubled from last year. More importantly, though, these were active users looking for new info and willing to share their experiences. Many sessions were standing room only with great Q&A that added to greatly to the experience.

The sessions were great

One of the standing room only talks was a sessions about adjusting resources (a subject near and dear to our hearts, of course) that discussed the tools, processes and difficulties https://schd.ws/hosted_files/kccna18/17/Getting%20The%20Most%20Out%20Of%20Kubernetes.pdf.

Chris Dutra, from Schireson, had a great session https://schd.ws/hosted_files/kccna18/35/ProML-Scaling.pdf and I enjoyed Beata Skiba’s https://schd.ws/hosted_files/kccna18/1f/VPA%20Kubecon%20Seattle.pdf and Thomas Rampelberg’s https://schd.ws/hosted_files/kccna18/8a/slides.pdf presentations.

Ross Kukulinski from Heptio had a great session on k8s deployment primitives including discussions of rolling upgrades, rollbacks, canaries and blue green deployments https://schd.ws/hosted_files/kccna18/d6/KubeCon%20Front-end%20Application%20Deployment%20Patterns%20-%20v2.pdf

There were a lot more user journey presentations

A big part of the power of community is sharing user experiences so we don’t all stub our toes on the same sharp edges. That’s why it was great to see there were a lot more users talking about their journeys than in past years. Many demonstrate transition problems still exist (both human and non-human), but that’s important to surface. I particularly enjoyed the T-mobile story shared by James Webb and Brendan Aye https://schd.ws/hosted_files/kccna18/f7/T-Mo%20OP%20K8S.pdf as well Melanie Cebula’s presentation https://schd.ws/hosted_files/kccna18/1f/kubecon%202018.pdf.   

Kubernetes has made the transition to production

While all the foregoing would have been enough for a successful event, what I found most interesting was the significant production adoption beginning to show up. Roughly half of attendees had production deployments, which is a shift from previous years when most were running tests in labs. Even more important, they weren’t all single apps. T-mobile’s presentation, for instance, lists 3-4 apps now running in production. 2018 marked a distinct maturation of Kubernetes and bodes very well for 2019.
