Container security fundamentals part 4: Cgroups

Managing system resources can be a challenge when multiple processes are running on a host. A single misbehaving program could consume all available resources, causing the entire system to crash. To tackle this problem, Linux relies on control groups (cgroups) to manage each process's access to resources, such as CPU and memory.

Docker and other containerization tools use cgroups to restrict the resources that containers can use, which can help avoid "noisy neighbor" issues. This is particularly helpful when working …
