Crate allows to query and compute data with SQL in real time by providing a distributed aggregation engine, native search and super simple scalability. It offers auto-sharding and replication, super-fast multi index queries, distributed aggregations and sort, superfast full-text search, and super simple cluster management.

Simply run the latest Crate version in a Docker container with the following command. Crate ships with an Admin UI that provides an overview of your cluster, nodes, tables and much more. With the above command it is accessible via port 4200.

$ docker run -d -p 4200:4200 -p 4300:4300 crate:latest

If you want to attach a persistent data directory, add the following parameter.

$ docker run -d -p 4200:4200 -p 4300:4300 -v <data-dir>:/data crate

Use the following parameter to provide your custom Crate configuration file.

$ docker run -d -p 4200:4200 -p 4300:4300 crate -Des.config=/path/to/crate.yml

Any configuration settings may be specified upon startup using the -D option prefix. For example, configuring the cluster name by using system properties will work this way:

$ docker run -d -p 4200:4200 -p 4300:4300 crate crate -Des.cluster.name=cluster

To set environment variables for Crate Data you need to use the --env option when starting the docker image.

For example, setting the heap size:

$ docker run -d -p 4200:4200 -p 4300:4300 --env CRATE_HEAP_SIZE=32g crate

Crate uses multicast for node discovery by default. However, Docker does only support multicast on the same host. This means that nodes that are started on the same host will discover each other automatically, but nodes that are started on different hosts need unicast enabled.

You can enable unicast in your custom crate.yml. See also: Crate Multi Node Setup.

Due to its architecture, Crate publishes the host it runs on for discovery within the cluster. Since the address of the host inside the docker container differs from the actual host the docker image is running on, you need to tell Crate to publish the address of the docker host for discovery.

$ docker run -d -p 4200:4200 -p 4300:4300 crate crate -Des.network.publish_host=host1.example.com:

If you change the transport port from the default 4300 to something else, you also need to pass the publish port to Crate.

$ docker run -d -p 4200:4200 -p 4321:4300 crate crate -Des.transport.publish_port=4321

$ HOSTS='crate1.example.com:4300,crate2.example.com:4300,crate3.example.com:4300'
$ HOST=crate1.example.com
$ docker run -d \
	-p 4200:4200 \
	-p 4300:4300 \
	--name node1 \
	--volume /mnt/data:/data \
	--env CRATE_HEAP_SIZE=8g \
	crate:latest \
	crate -Des.cluster.name=cratecluster \
		  -Des.node.name=crate1 \
		  -Des.transport.publish_port=4300 \
		  -Des.network.publish_host=$HOST \
		  -Des.multicast.enabled=false \
		  -Des.discovery.zen.ping.unicast.hosts=$HOSTS \
