summary
Dragonfly is a p2p image/file distrib system with a new decentralized mode that removes the heavyweight supernode by syncing peer/file state via Serf gossip and custom events (download init/progress/remove, checksum, recovery). Components built: DFGet client, DFDaemon host proxy, tracker interface and pluggable peer discovery (Kubernetes API, DNS, Serf agent). Claim: 2,000 nodes pulling ~1.5GB images achieves ~5 minutes 90th‑percentile in experiments. Integrations exist for containerd, Harbor preheat, Prometheus metrics, and a plugin framework for custom distribution strategies.
