Getting Started with Docker

KeyDB Enterprise docker images#

You can find the docker repository here:

If you need a brushup on any of the docker commands you can check out dockers documentation here

Start a KeyDB Enterprise instance without a license key#

Please note that if you do not input a license key, it will start in demo-mode with a 2hr timeout after which the server will be killed. This can be used for basic testing, however if you are in need of a longer trial period for POC testing, please contact to get set up.

docker run --name some-keydb -d eqalpha/keydb-enterprise

From above, --name specifies a name for the container, its not needed but makes it easier to identify. The -d option is 'detached' or runs in the background.

Pass configuration parameters to KeyDB Enterprise on boot:#

docker run -name some-keydb -d eqalpha/keydb-enterprise keydb-server /etc/keydb/keydb.conf --server-threads 8 --requirepass password --enable-enterprise LKXX-XXXX-XXXX-XXXX-XXXX

Make sure you specify the program you are running (keydb-server) for which to modify the parameters for. Next specify the config parameter you would like to modify when starting the container with --parameter-name value. You can see the full set of configuration options here

Bind port#

If you want to bind the container to the node/machine so it is accessible externally pass the parameter -p 6379:6379

If you would like to use your own config file#

$ docker run -v /path-to-config-file/keydb.conf:/etc/keydb/keydb.conf --name mykeydb -d eqalpha/keydb-enterprise

If you are using your own config file remember to comment out "bind", change "protected-mode" from yes to no.

you can grab a copy of the default config file off our github page and modify as you see fit.


As requested by users for Redis compatibility, we have included symbolic links for both redis-cli and redis.conf so they are linked to keydb-cli and keydb.conf respectively.

Using Enhanced FLASH Storage#

sudo docker run -d -it --name mycontainername --mount type=bind,dst=/flash,src=/path/to/flash/ eqalpha/keydb-enterprise keydb-server /etc/keydb/keydb.conf --enable-enterprise LKXX-XXXX-XXXX-XXXX-XXXX --storage-provider flash /flash --maxmemory [maxmemory-amount-ie. 2G] --eviction-policy [eviction-policy ie. allkeys-lru]

You need to mount your flash storage volume (ssd/flash) to the docker container so it has a place to write its data. src=/path/to/flash references the location you have set up. Specify -it' to enable the container to communicate with it. The docker container already has a directory inside it named /flashwhich we will use internally as a reference.--storage-provider [storage-type][storage-location] is used to specify the storage type and location. For this docker container it will always be --storage-provider flash /flash.

To see more about FLASH sizing check out docs

The FLASH storage provider is always persistent. There is no requirement to save or load RDB files if FLASH is used. You may disable periodic RDB saving by adding: save "" to your configuration file. On boot KeyDB will load any existing data in your FLASH database.

Connect to it from an application#

$ docker run --name some-app --link some-keydb:eqalpha/keydb-enterprise -d application-that-uses-keydb

Or connect via keydb-cli (also compatible with redis-cli)#

you can grab the ip of the container with docker inspect --format '{{ .NetworkSettings.IPAddress }}' mycontainername then run the following:

docker run -it --rm eqalpha/keydb-enterprise keydb-cli -h [ipaddress-from-above] -p 6379

alternatively you can link to it

$ docker run -it --link some-keydb:eqalpha/keydb-enterprise --rm eqalpha/keydb-enterprise keydb-cli -h keydb -p 6379
