deep-dive - Dario Tranchitella
summary
A technical deep dive into how Kubernetes Pods actually work, focusing on the pause container code (about 40 lines that handle signals), how containers in a Pod run real processes via Docker and systemctl, and how a shared volume is wired so two containers truly share state. Presents a mini orchestrator implementation that creates pods, binds volumes, and restarts failed processes, with a live demo applying concrete patterns such as init containers and ambassador containers.
