apt-cacher-ng

apt-cacher-ng is a caching HTTP proxy for Debian and Ubuntu apt repositories. The first host on the LAN to fetch a .deb populates the cache; every subsequent apt-get install / apt-get dist-upgrade on any other host serves the same package from local disk — saving WAN bandwidth and turning multi-minute upgrades into seconds.

Key Features

• Transparent HTTP proxy in front of deb.debian.org / archive.ubuntu.com / vendor mirrors
• Single-port (3142), single-container deployment
• Per-package hit-rate report at /acng-report.html
• Survives container restart — cache lives on a host bind-mount
