Mini-summit proposal: Linux Kernel Containers Developer Summit
Topic
Namespaces, containers, cgroups, and container checkpoint/restart.
Description
Development for namespaces and cgroups is well underway in the mainline kernel. To keep momentum going and keep the loosely knit teams of developers well-coordinated, a physical meeting in which to discuss future development plans is needed. Additionally, we are at a point where crucial decisions about the nature of a "container object" and about the checkpoint/restart design need to be made.
A final set of topics will be decided upon through mailing lists ahead of time, but potential topics include:
- Handling filesystem/namespace synchronization
- Handling of /proc and /sysfs within containers
- Additional needed namespaces (i.e. device namespace)
- Nature of a 'container' — kernel object or userspace fiction
- Cgroup implementation
- Additional cgroups and their design
- Resource management
- How to initiate and synchronize checkpoint/restart
- How to enter a 'container'
