Currently, starting RDMS after rebuilding and reinstalling it from
scratch in `RAILS_ENV=production` mode fails because assets are not
created automatically. I'd prefer to put the required commands into the
`Dockerfile`, but this doesn't work currently because the path used to
store these assets is a Docker volume shared between multiple Docker
containers, which are not available at build time of these container
images/execution time of the corresponding `Dockerfile`. Therefore, for
the time being, we execute the commands in the container's
`hyrax/docker-entrypoint.sh`.
