Linux Kernel Modules That Explain How Podman Really Works

This piece delves into how Podman operates by building and running three Linux kernel modules that highlight essential OS concepts like kernel debug messages, character devices, and the interplay between kernel and user-space processes. Set in a disposable Ubuntu environment on Killercoda, the author leverages the kernel-modules repository for the source code. This exploration is significant for understanding how container technologies like Podman function at a deeper level, offering insights into both kernel-level operations and container management.
