If this struck your interest, but you want more nitty gritty examples and details, you may find the following article interesting: https://ericchiang.github.io/post/containers-from-scratch/

If I'm remembering correctly from when I ran through the instructions at home, it was written for the original cgroup sysfs interface rather than the more modern cgroup2 [0]. You can figure out which you're running with

> mount | grep cgroup > cgroup2 on /sys/fs/cgroup type cgroup2 (rw,nosuid,nodev,noexec,relatime,nsdelegate,memory_recursiveprot)

which turns the examples is a nice "check your understanding"
