ugos docker updating info

[Brian B]

I installed using the ugos installation app for Jellyfin.  It completed and I got everything working.  It used 10.10.3 and I would like to upgrade to 10.10.7.  I do not know how to implement the upgrade (I did the windows upgrades no issues).  I understand how to shutdown the jellyfin docker, i just don't know how to upgrade. I don't have access to command line directly.  I just found a way to install a terminal in the docker container.  It shows /bin/bash.  What are my steps to upgrade to the latest.  do i just enter commands and what commands would allow me to keep my current installation info without losing the /data and /config directories created by the installation app?

Thanks in advance. Sorry I don't know Docker, ugos and debian linux enough.  So far I like the docker version but I just need some assistance.
