If you'd like to get a Redis instance up and running to play with it's fairly easy via Docker.
docker run --name my-redis -p 6379:6379 -d redis redis-server --appendonly yes
This will start a Redis instance with the name
my-redis with persistent storage turned on. You can also
start with Redis CLI via Docker.
docker run --link my-redis -it --rm redis redis-cli -h my-redis
You'll need to replace
my-redis with whatever you named your Redis instance of course.
