## Run
Edit `environment` to suite. Run 'docker-compose -f distribution/docker/docker-compose.yml up`
## mysql database connector
This image contains solely the postgres metadata database connector. If you need
the mysql metadata storage connector, consider adding these lines before the `addgroup`
run-command.

Alternatively, cd src/distribution/docker; docker build -t druid:mysql --build-arg DRUID_RELEASE=upstream -f Dockerfile.mysql .
where `upstream` is the version to use as the base (e.g. druid:0.14.0 from Dockerhub)
