Containers micro-conference at Linux Plumbers 2018


This year’s edition of the Linux Plumbers Conference will once again feature a containers micro-conference. This is a great occasion for users and developers of Linux container technology to meet and talk about the feature.

One change compared to previous editions is that this time we’ve extended the micro-conference to cover topics that in the last years were part of the Checkpoint-Restart micro-conference. This means we’ll be running a 6 hours long event rather than 3 hours.

LPC 2018 will be held in Vancouver, British Columbia from the 13th until the 15th of November 2018, co-locating with the Linux Kernel Summit. The venue is the Sheraton Vancouver Wall Centre Hotel.


Similar to last year’s edition, we will focus on interesting discussion topics and short presentations/demos of recent or ongoing work.

We expect to time limit presentations/demos to 15 minutes including questions.
More open ended discussion topics will get up to 30 minutes allocated.
There is always time for longer discussions after the micro-conference!


Below are some ideas of content that we think would be a good fit for this edition:

  • New mount API
  • System call filtering and interception
  • Performance improvement for containers (following Spectre/Meltdown mitigation)
  • CGroupV2 developments
  • Mount propagation handling
  • Linux Security Modules inside containers
  • Uevent namespacing
  • UID shifting filesystem (shiftfs)
  • CRIU integration with container engines and orchestration frameworks
  • (In)stability of less commonly used kernel ABIs
  • Time namespacing
  • Checkpoint/Restart performance improvements

Some of those are ideas in search of an acceptable solution, some are problems likely to affect all container runtimes and some are coverage of very recent kernel work and how that can be used by userspace.


Please send your proposals by e-mail to and include the following in your submission:

  • Title
  • Abstract (few paragraphs on what it is you want to talk about)
  • Format (presentation or discussion)
  • Presenter (you, a group of people or nobody if you just want to suggest something)
  • Duration (normally 15min for presentations, 30min for discussions)
  • Registration status (registered, will register or require free ticket in order to attend)

We’ll accept proposals for this micro-conference until the 14th of September 2018.

Do note that speaking at a micro-conference doesn’t automatically get you access to the conference. Each micro-conference has access to a limited number of free or discounted passes but we prefer to hand those out to those who couldn’t otherwise afford to attend the conference.

If you will need one of those passes in order to present at the conference, please let us know by adding a note in your proposal.

Looks great! I would attend if I were gainfully employed. Any interest in a talk about ‘Hobbyist uses of LXD in a homelab using old, modest hardware and new, cutting-edge software to escape the cloud’? for a free ticket? :wink:

Not sure that plumbers would have been the best audience for that, Open Source Summit would be a better fit I’d think, and most conferences will give you a free speaker pass if your talk gets in, so it’s always worth a try :slight_smile:
