What's CGManager Doing and Why is it Still Relevant - Serge Hallyn, Canonical

Sign up or log in to save this to your schedule and see who's attending!

The cgroup manager (cgmanager) is an effort by the LXC project to
address a specific set of goal: support unprivileged nesting and
nesting to multiple levels; allow userspace in containers to
administer their delegated cgroups the same way as on the host; and
simplify the cgroup code in lxc itself.

We will describe the requirements, design, and API. We will go over
the specific security guarantees and show how cgmanager provides these
guarantees for each API method. Finally we will discuss - and hopefully
receive input on - the relation of cgmanager to other parts of the linux
ecosystem including libcontainer, criu, and systemd, and discuss next steps.
