DockerCon 2015 Wrap-Up

I attended DockerCon 2015 in San Francisco from June 22-23. The official wrap-ups for Day 1 and Day 2 are available from Docker, Inc. Keynote videos are posted here. Slides from every presentation are available here.

Here are my personal notes and take-aways from the conference:

The Good

  • Attendance was much larger than I expected, reportedly at 2,000 attendees. It reminded me a lot of VMworld back in 2007. Lots of buzz.
  • There were many interesting announcements in the keynotes:
    • Diogo Mónica unveiled and demoed Notary, a tool for publishing and verifying the authenticity of content. (video)
    • Solomon Hykes announced that service discovery is being added into the Docker stack. Currently one needs to use an external tools like registrator, Consul, and etcd for this.
    • Solomon announced that multi-host networking is coming.
    • Solomon announced that Docker is splitting out its internal plumbing from the Docker daemon. First up is splitting out the container runtime plumbing into a new project called RunC. The net effect is that this creates a reusable component that other software can use for running containers. This will also make it easy to run containers without the full Docker daemon as well.
    • Solomon announced the Open Container Project & Open Container Format – Basically Docker, Inc. and CoreOS have buried the hatchet and are working with the Linux Foundation and over a dozen other companies to create open standards around containers. Libcontainer and RunC are bring donated to this project by Docker, while CoreOS is contributing the folks who were working on AppC. More info on the announcement here.
    • Docker revealed how they will start to monetize their success. They announced an on-prem Docker registry with a support plan starting at $150/month for 10 hosts.
  • Diptanu Choudhury unveiled Netflix’s Titan system in Reliably Shipping Containers in a Resource Rich World using Titan. Titan is a combination of Docker and Apache Mesos, providing a highly resilient and dynamic PaaS that is native to public clouds and runs across multiple geographies.
  • VMware announced he availability of AppCatalyst, a free, CLI-only version of VMware Fusion. That software, combined with the Vagrant plugin for AppCatalyst that Fabio Rapposelli released, means that developers no-longer need to pay for VMware Fusion in order to have a more stable and performant alternative to Oracle’s VirtualBox for use with Vagrant. William Lam has written a great Getting Started Guide for AppCatalyst.
  • The prize for most entertaining presentation goes to Bryan Cantrill for Running Aground: Debugging Docker in Production. Praise for his talk & funny excerpts from that talk were all over Twitter:

The Bad

I was pretty disappointed with most of the content of the presentations on the “Advanced” track. There were a lot of fluffy talks about micro-services, service discovery, and auto-scaling groups. Besides not getting into great technical detail, I was frustrated by these talks because there was essentially no net-new content for anyone who frequents meetups in the Bay Area, follows Hacker News, or follows a few key accounts on Twitter.

Speaking to other attendees, I found that I was not the only one who felt that these talks were very high-level and repetitive. Bryan Cantrill even eluded to this in his own talk when he mentioned “micro-services” for the first time, adding, “Don’t worry, this won’t be one of those talks.”

Closing Thoughts

I had a great time at DockerCon 2015. The announcements and presentations around security and network were particularly interesting to me because there were new things being announced in those areas. I could have done w/o all of the fluffy talks about micro-services and auto-scaling.

It was also great to meet new people and catch up with former colleagues. I got to hear a lot of interesting ways developers are using Docker in their development and production environments and can’t wait to implement some of the things I learned at my current employer.
