I am probably biased but offer my two cents.
From the Plex perspective only:
-
Docker portability has not proven itself to me. I have 3 docker-capable systems Fedora, Synology, and QNAP. I cannot move a Docker container from one to another without getting “illegal container format” or other such ridiculous error.
-
Linux native portability far outstrips this. A tar ball or ZIP file of
./Libraryand it’s done. You can even take it to MacOS or Windows. -
Hardware transcoding in docker requires you hack the base Linux OS. No two ways around it. Should you install the native app, my installer does it all for you automatically and maintains it as well.
With respect to other Docker containers, Go for it. Those apps are small and, due to their operational scope, are easily contained because they are largely file i/o and internet downloading based.
My delimiting point is: Utility or Service.
PMS is a service because it streams and does a lot of heavy lifting CPU-wise.
Sonarr, Nzbget, etc, are utilities because they receive only and very CPU light.
