   # [DRILL-8293](https://issues.apache.org/jira/browse/DRILL-8293): Add a docker-compose file to run Drill in cluster mode
   
   ## Description
   
   This directory contains source code artifacts to launch Drill in cluster mode
   along with a ZooKeeper. The Drill image is based on a minor customisation of
   the official Drill image that switches it from an embedded to a cluster mode
   launch. Logging is redirected to stdout.
   
   In the docker-cluster-mode directory:
   
   1. docker build -t apache/drill-cluster-mode
   2. docker-compose up
   
   Then access the web UI at http://localhost:8047 or connect a JDBC client to
   jdbc:drill:drillbit=localhost or jdbc:drill:zk=localhost but note that you
   will need to make the drillbit container hostnames resolvable from the host to 
   use a ZooKeeper JDBC URL.
   
   To launch a cluster of 3 Drillbits
   
   3. docker-compose up --scale drillbit=3
   
   but first note that to use docker-compose's "scale" feature to run multiple
   Drillbit containers on a single host you will need to remove the host port
   mappings from the compose file to prevent collisions (see the comments
   on the relevant lines in that file). Once the Drillbits are launched run
   `docker-compose ps` to list the ephemeral ports that have been allocated on
   the host.
   
   
   ## Documentation
   Add the above discussion to the Drill in Docker doc page.
   
   ## Testing
   Launch Drill using the provided commands and run queries.

> Add a docker-compose file based on the official Docker images but overriding the ENTRYPOINT to launch Drill in cluster mode and including a ZooKeeper container. This can be used to experiment with cluster mode on a single machine, or to run a real cluster on platforms that work with docker-compose like Docker Swarm or ECS.
