This is aDockerfile
method to create a Docker container image for Redis.
Redis is an open source, BSD licensed, advanced key-value cache and store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs.
Automated builds of the image are available on Dockerhub and is the recommended method of installation.
docker pull absolootly/docker-redis:latest
Alternatively you can build the image yourself.
docker build -t absolootly/docker-redis github.com/simontakite/docker-redis
Start Redis using:
docker run --name redis -d --restart=always \
--publish 6379:6379 \
--volume /srv/docker/redis:/var/lib/redis \
absolootly/docker-redis:latest
Alternatively, you can use the sample docker-compose.yml file to start the container using Docker Compose
You can customize the launch command of Redis server by specifying arguments to redis-server
on the docker run
command. For example the following command will enable the Append Only File persistence mode:
docker run --name redis -d --restart=always \
--publish 6379:6379 \
--volume /srv/docker/redis:/var/lib/redis \
absolootly/docker-redis:latest --appendonly yes
Please refer to http://redis.io/topics/config for further details.
For Redis to preserve its state across container shutdown and startup you should mount a volume at /var/lib/redis
.
The Quickstart command already mounts a volume for persistence.
SELinux users should update the security context of the host mountpoint so that it plays nicely with Docker:
mkdir -p /srv/docker/redis
chcon -Rt svirt_sandbox_file_t /srv/docker/redis
To secure your Redis server with a password, specify the password in the REDIS_PASSWORD
variable while starting the container.
docker run --name redis -d --restart=always \
--publish 6379:6379 \
--env 'REDIS_PASSWORD=redispassword' \
--volume /srv/docker/redis:/var/lib/redis \
absolootly/docker-redis:latest
Clients connecting to the Redis server will now have to authenticate themselves with the password redispassword
.
Alternatively, the same can also be achieved using the Command-line arguments feature to specify the --requirepass
argument.
By default the Redis server logs are sent to the standard output. Using the Command-line arguments feature you can configure the Redis server to send the log output to a file using the --logfile
argument:
docker run --name redis -d --restart=always \
--publish 6379:6379 \
--volume /srv/docker/redis:/var/lib/redis \
absolootly/docker-redis:latest --logfile /var/log/redis/redis-server.log
To access the Redis logs you can use docker exec
. For example:
docker exec -it redis tail -f /var/log/redis/redis-server.log
To upgrade to newer releases:
- Download the updated Docker image:
docker pull absolootly/docker-redis:latest
- Stop the currently running image:
docker stop redis
- Remove the stopped container
docker rm -v redis
- Start the updated image
docker run --name redis -d \
[OPTIONS] \
absolootly/docker-redis:latest
docker exec -it redis bash
