## Set a default user. Available via runtime flag `--user docker`

EXPOSE 8787
CMD ["/init"]
I logged to the docker container with docker run -it -v /home/galaxy:/export rstudio bash and it showed me the following
ls -ahl
drwxr-xr-x 43 dudleyk galaxy 4.0K Apr 8 00:09 export
How do I give the second user write, executable and read access to the export?
Thank you in advance
