# [DRILL-8156](https://issues.apache.org/jira/browse/DRILL-8156): Declare
and chown a /data VOLUME in the Drill Dockerfile
## Description
Some users of embedded Drill in Docker want to use a Docker volume with
Drill, particularly for Drill's persistent local storage so that Drill
configuration can persist across container launches. Because Drill no longer
runs as root in the Docker container as of 1.20, these users now need a
mountpoint inside that container that has been chowned to drilluser.
Also remove unneeded permissions to Drill installation dir that were held by
drilluser.
## Documentation
Document the existence of the volume mountpoint at /data in the container.
## Testing
1. Build an image using Drill master and the Dockerfile in this branch.
2. Launch the image with default args (no volume mounted) and run test
queries. Confirm that an option set with ALTER SYSTEM is lost across container
launches.
3. Launch the image with a host volume mounted at /data and
`sys.store.provider.local.path: "/data"` and run test queries. Confirm that an
option set with ALTER SYSTEM is persisted across container launches.
