It is simple to start using Redis using docker:
docker pull redis
docker run -p 6379:6379 --rm --name redis redis
Now you have running instance on port 6397
Attention: All data will be deleted, when Redis will be stopped.
To connect the redis-cli, start another docker:
docker run -it --link redis:redis --rm redis redis-cli -h redis -p 6379
Now you can play around with your redis docker.
