Im rather new to Docker as I just installed the Docker plugin (running Plex, Emby, Transmission-OpenVPN) in the last month.
While my containers were running, a new version of Plex was released and I realized that in order to upgrade I had to stop the running container, start a new container based on the new image while pointing at the existing configuration.
I soon realized that I had to set again all he options (paths, PUID, PGID, etc.); while this I straight forward for Plex and Emby (5 shares, 3 options), it would be a pain for Transmission-OpenVPN where I customized 30 or more options.
So, here comes my question.
Is there a way to backup/store a configuration file and then start a new container using this file (without having to set again manually all the options)?
Thank you all.
