Exposing resource limits to containers with LXCFS


One Line Summary

Introduction to the problem of cgroup limits visibility to userspace and the approach taken by LXCFS.


There are some difficult challenges ahead for LXCFS, if it chooses to accept them:
1. implementing support for /sys/devices/system/cpu
2. addressing loadavg
3. whether/how to help address sysinfo(2) system call (not in scope for fs, but in scope for LXCFS’s missions).

In this talk we’d like to spend some time discussing possible approaches to each of these three, as well as, maybe, possibly, encouraging future contributors to join in.
