# What is Redis?

Redis is an open-source, networked, in-memory, key-value data store with
optional durability. It is written in ANSI C. The development of Redis has been
sponsored by Pivotal since May 2013; before that, it was sponsored by VMware.
According to the monthly ranking by DB-Engines.com, Redis is the most popular
key-value store. The name Redis means REmote DIctionary Server.

# How to use this image

## start a redis instance

    docker run --name some-redis -d redis

This image includes `EXPOSE 6379` (the redis port), so standard container
linking will make it automatically available to the linked containers (as the
following examples illustrate).

## start with persistent storage

    docker run --name some-redis -d redis redis-server --appendonly yes

If persistence is enabled, data is stored in the `VOLUME /data`, which can be
used with `--volumes-from some-volume-container` or `-v /docker/host/dir:/data`
(see [docs.docker volumes](http://docs.docker.com/userguide/dockervolumes/)).

For more about Redis Persistence, see
[http://redis.io/topics/persistence](http://redis.io/topics/persistence).

## connect to it from an application

    docker run --name some-app --link some-redis:redis -d application-that-uses-redis

## ... or via `redis-cli`

    docker run -it --link some-redis:redis --rm redis sh -c 'exec redis-cli -h "$REDIS_PORT_6379_TCP_ADDR" -p "$REDIS_PORT_6379_TCP_PORT"'

## Additionally, If you want to use your own redis.conf ...

You can create your own Dockerfile that adds a redis.conf from the context into
/data/, like so.

    FROM redis
    COPY redis.conf /usr/local/etc/redis/redis.conf
    CMD [ "redis-server", "/usr/local/etc/redis/redis.conf" ]

Alternatively, you can specify something along the same lines with `docker run`
options.

    docker run -v /myredis/conf/redis.conf:/usr/local/etc/redis/redis.conf --name myredis redis /usr/local/etc/redis/redis.conf

Where `/myredis/conf/` is a local directory containing your `redis.conf` file.
Using this method means that there is no need for you to have a Dockerfile for
your redis container.
