Redis is an open source, BSD licensed, advanced key-value cache and store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs.
This version is designed to run in a Docker instance on a Raspberry Pi. The Dockerfile was shamelessly borrowed (stolen) from the Official Redis Docker Image.
Docker for the Raspberry Pi as well as Docker friendly debian images can be located here.
