Steamcache

A light weight series of services that allow caching of steam downloads, windows updates and more!

Warning

Please note this is a set of 3 services that work well for caching downloaded content. HOWEVER, you will be poisoning your DNS records and creating a small Man-In-The-Middle attach for some services. These are very real concerns that should be considered before running these services.

Hardware Concerns

The official docs state you'll want "big, dedicated hardware". They are not lying. You'll want at least a 500Gb HD, preferably >1Tb and likely an O-Droid HC2 dedicated to this setup.

This setup also assumes you will only be running steamcache on the main, wired network adapter with no firewall.

We do NOT recommend running Steamcache alongside any other services. There are too many ways things can go wrong when putting this service alongside others.

Prep Install

Simply execute /root/steamcache*.sh to update/run all of the steamcache containers/services.
