Redis Docker Image based on Official Redis Image with support for Redis cluster.
Full Description

About

This repository contains files to create Docker image for Redis from Official Redis Image with support for Redis cluster.

The image/packages used are pinned to a version number in the Dockerfile to ensure image stability.

Automated builds of the image are available on the Docker Hub.

Usage

To start a Redis instance:

docker run --name <container-name> -d seekasia/redis:<tag>

Additionally if you want to mount the data directory or specifying the custom configuration file:

docker run \
--net=host \
-v <data-dir>:/data \
-v <logrotate-conf>:/etc/logrotate.d/redis \
-v <redis-conf>:/usr/local/etc/redis/redis.conf \
--name <container-name> -d seekasia/redis:<tag> \
redis-server /usr/local/etc/redis/redis.conf

Docker's networking layer affects the performance significantly, if possible, run the container with --net=host to use host networking to improve the throughput as shown above.

This also a proposed solution for running Redis cluster from different hosts where the Docker's internal address unreachable by other Redis nodes in the cluster.

Timezone

You can use the environment variable to modify the timezone in the container (Default to Asia/Singapore):

-e TZ=<timezone>

redis-trib

The Ruby utility used to facilitate Redis cluster administration is called redis-trib-pass.rb, an enhanced version of the redis-trib.rb with added support for authentication.

Run any redis-trib command as follow:

redis-trib-pass.rb help
redis-trib-pass.rb create --auth <password> 192.168.11.11:7001 192.168.11.11:7002 192.168.11.11:7003
