⁠Version

The current release (2.8.14) contains scripts to install Redis Server v2.8.14, and uses the Brightcommerce Ubuntu 14.04 base image. Our version numbers will reflect the version of Redis Server being installed.

⁠Installation

Pull the latest version of the image from the Docker Index. This is the recommended method of installation as it is easier to update the image in the future. These builds are performed by the Docker Trusted Build service.

docker pull brightcommerce/redis:latest

or specify a tagged version:

docker pull brightcommerce/redis:2.8.14

Alternately you can build the image yourself:

git clone https://github.com/brightcommerce/docker-redis.git
cd docker-redis
docker build -t="$USER/redis" .

⁠How To Use

Run the Redis image:

docker run --name redis -d brightcommerce/redis:latest

To test if the Redis server is configured properly, try connecting to the server.

redis-cli -h $(docker inspect --format {{.NetworkSettings.IPAddress}} redis)

If the redis-cli client isn't installed on the host you can use docker-enter to shell into the container and run it from there:

sudo docker-enter redis
root@9a34e83ea636:~# redis-cli

⁠Configuration

⁠Ports

This installation exposes port 6379.

⁠Data Store

For data persistence a volume should be mounted at /var/lib/redis.

The updated run command looks like this:

mkdir -p /opt/redis
docker run -name redis -d -v /opt/redis:/var/lib/redis brightcommerce/redis:latest

This will make sure that the data stored in the database is not lost when the image is stopped and restarted.

⁠Upgrading

To upgrade to newer releases, simply follow this 3 step upgrade procedure.

• Step 1: Stop the currently running image:

docker stop redis

• Step 2: Update the docker image:

docker pull brightcommerce/redis:latest

• Step 3: Start the image:

docker run -name redis -d [OPTIONS] brightcommerce/redis:latest
