tutum-docker-redis

Base docker image to run a Redis server

Usage

To create the image tutum/redis, execute the following command on the tutum-redis folder:

docker build -t tutum/redis .

Running the Redis server

Run the following command to start Redis:

docker run -d -p 6379:6379 tutum/redis

The first time that you run your container, a new random password will be set. To get the password, check the logs of the container by running:

docker logs <CONTAINER_ID>

You will see an output like the following:

========================================================================
You can now connect to this Redis server using:

    redis-cli -a 5elsT6KtjrqVtOitprnDm7M9Vgz0MGgu -h <host> -p <port>

Please remember to change the above password as soon as possible!
========================================================================

In this case, 5elsT6KtjrqVtOitprnDm7M9Vgz0MGgu is the password set. You can then connect to Redis:

redis-cli -a 5elsT6KtjrqVtOitprnDm7M9Vgz0MGgu

Done!

Setting a specific password

If you want to use a preset password instead of a random generated one, you can set the environment variable REDIS_PASS to your specific password when running the container:

docker run -d -p 6379:6379 -e REDIS_PASS="mypass" tutum/redis

You can now test your deployment:

redis-cli -a mypass

If you hope redis work without password, you can set REDIS_PASS to **None**:

docker run -d -p 6379:6379 -e REDIS_PASS="**None**" tutum/redis

Configuring Redis as a LRU cache

In order to run Redis as a cache that will delete older entries when the memory fills up provide the following additional environment variables:

docker run -d -p 6379:6379 -e REDIS_MODE="LRU" -e REDIS_MAXMEMORY="256mb" tutum/redis

where REDIS_MODE is LRU and REDIS_MAXMEMORY is the memory limit in which Redis will start deleting the less recently used (LRU) keys.
