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 to run Drill in cluster mode > ------------------------------------------------------ > > Key: DRILL-8293 > URL: https://issues.apache.org/jira/browse/DRILL-8293 > Project: Apache Drill > Issue Type: Improvement > Components: Server > Affects Versions: 1.20.2 > Reporter: James Turton > Priority: Minor > Fix For: 1.20.3 > > > 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.
