How Containers Work: Building Container Networking from Scratch

I wrote a deep dive on how container networking actually works by building it manually from Linux primitives.

Instead of treating container networking as a black box, this walks through network namespaces, veth pairs, routing tables, and NAT with iptables

Would love feedback from folks working on infra, Linux networking, or container platforms.
