Optimizing Large Docker Images for iQIYI Video Transcoding: Differential Build, On‑Demand Download, Deduplication, and Distribution Strategies
iQIYI’s video transcoding team cut its Docker image size from 18 GB to 9 GB and build time from 30 minutes to under five by layering differential builds, on‑demand downloads, library deduplication, node pre‑warming with gray releases, and P2P distribution via Dragonfly, all without requiring developer changes.
