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 is sponsored by Redis Labs today; before that, it was sponsored by
Pivotal and 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).

For more about Redis Persistence, see 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 redis-cli -h redis -p 6379

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 redis-server /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.

32bit variant

This variant is not a 32bit image (and will not run on 32bit hardware), but includes Redis compiled as a 32bit binary, especially for users who need the decreased memory requirements associated with that. See "Using 32 bit instances" in the Redis documentation for more information.

Redis Modules

You can find the list of modules for Redis on redis.io or on redismodules.com. A few of the standard modules can be found here:

• RediSearch: Search and Query with Indexing on Redis
• ReJSON: Extended JSON processing for Redis
• ReBloom: Bloom Filters data type for membership/existence search on Redis

Image Variants

The redis images come in many flavors, each designed for a specific use case.

redis:<version>

This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.

redis:alpine

This image is based on the popular Alpine Linux project, available in the alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.

This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn't have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.

To minimize image size, it's uncommon for additional related tools (such as git or bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the alpine image description for examples of how to install packages if you are unfamiliar).

License

View license information for the software contained in this image.

As with all Docker images, these likely also contain other software which may be under other licenses (such as Bash, etc from the base distribution, along with any direct or indirect dependencies of the primary software being contained).

Some additional license information which was able to be auto-detected might be found in the repo-info repository's redis/ directory.

As for any pre-built image usage, it is the image user's responsibility to ensure that any use of this image complies with any relevant licenses for all software contained within.
