docker-redis-cluster is a docker image containing a 6 node redis cluster. There will be three master nodes running on ports 6379, 6380, and 6381 and three slave nodes running on ports 6382, 6383, and 6384.
The docker image that this creates has only been tested in low traffic environments. Currently, I have no idea how this will hold up in a production environment.
This image can be found on Dockerhub here
