Run Redis Community Edition on Docker

How to run Redis Community Edition using Docker

Run Redis Community Edition (CE) on Docker

To start Redis Community Edition server, using the redis:<version> image, run the following command in your terminal:

docker run -d --name redis -p 6379:6379 redis:<version>

Connect with redis-cli

You can then connect to the server using redis-cli, just as you connect to any Redis instance.

If you don’t have redis-cli installed locally, you can run it from the Docker container:

$ docker exec -it redis redis-cli

If you do have redis-cli installed locally, you can run it from your terminal:

$ redis-cli -h 127.0.0.1 -p 6379

Use a local configuration file

By default, the Redis Docker containers use internal configuration files for Redis. To start Redis with local configuration file, you can do one of the following:

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:/usr/local/etc/redis --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.

The mapped directory should be writable, as depending on the configuration and mode of operation, Redis may need to create additional configuration files or rewrite existing ones.
