A simple extension from docker-library official repo container for redis, that loads a redis.conf with settings wanted for OAO Production redis instance.
NB: This is also mentioned in the comments of redis.conf, but bears repeating and underscoring here: The intention of the config is that access will ONLY be allowed via linking from another container! So no external port should be exposed when the container is run, and note that the configuration follows redis defaults of listening across all network interfaces on port 6379.
