Distribute container images and large files to thousands of nodes fast — with peer-to-peer sharing, not a registry bottleneck.

Welcome to Dragonfly: Peer-to-Peer Image and File Distribution.

Dragonfly is a peer-to-peer file and container-image distribution system that lets machines share data with each other instead of all hammering one registry. This free book teaches it from the ground up: the distribution bottleneck at scale and P2P fundamentals, Dragonfly's architecture (Manager, Scheduler, Peers, and Seed Peers), how P2P distribution works with pieces, peer selection, and back-to-source, container image distribution via a transparent registry proxy, Kubernetes integration for fast rollouts and AI/model distribution, preheating and performance tuning, reliability with graceful fallback, security with piece verification and TLS, and operating Dragonfly in production. Ten focused chapters with clear diagrams that show how to turn slow, centralized distribution into a fast, scalable peer-to-peer swarm.

This title is part of the ShriIra library and is free to read in full, right here — our small contribution to making world-class knowledge easy to reach.
