Control groups (cgroups) are a method of grouping processes for the purpose of monitoring, management, and control. Using cgroups, we can: limit CPU and memory consumption; freeze and resume execution of a group; limit device access; limit the number of processes in a group; and more. Cgroups are a key building block in container systems and are also used in systemd. This tutorial provides an introduction to cgroups, covering both v1 and v2. The focus is on understanding the operation of the cgroup system itself, rather than going into details of individual controllers. So we'll look at how to create and populate cgroups using shell commands that operate on the cgroup filesystem and look at topics such as notification, inheritance, and delegation. Bring a laptop so you can walk through some of the examples.
