Hello! Thanks for using Rally 🙂

You may want to see our release Dockerfile ([here](https://github.com/elastic/rally/blob/master/docker/Dockerfiles/Dockerfile-release)). You can see there we use the USER directive to set the USER to `1000` (rally user) at the end of the file. If you're extending the image you may need to use an initial `USER root` directive to get through permissions issues, then go back with a `USER 1000`. Note also (as you can see in the Dockerfile) that COPY might require `--chown=1000:0` argument if you need the `rally` user to have access.

Note that what you're asking isn't really an esrally issue per se, our ability to help further might be limited

Thanks  
Rick B
