Migration of Plex to Docker - I need some help please

Hello everyone.

Since it looks like we will never get a repository for automatic updates for PMS on Synology NASes I’m about to migrate my PMS (latest stable version) to Docker on the same system. Currently I use the Synology NAS application of PMS.

Now here is what I tried:
First I stopped the PMS App so it won’t interfere with the Docker version of PMS (or so I thought). After I downloaded the Docker image of PMS and created a container I was able to successfully open the web UI via http://myNASIP:32400/web. The web UI tried to connect to my PMS but it just couldn’t do it. Looking back at it I think it is because I didn’t remove the PMS app which reserves port 32400. So I thought I just change the port of the container from 32400 to 32500 but then I couldn’t access the web UI at all. I later read that it’s impossible to change the port 32400.
Anyway, I deleted and created the container anew a few times, always with a new token from plex.tv/claim but no matter how many times I tried I just can’t acceess the web UI of the Docker PMS version anymore. It always says that the access is denied.

So my questions are:

  • Do I have to remove the PMS app first so the Docker PMS will work properly?
  • Why can’t I access the web UI of the Docker PMS anymore?
  • I want to migrate everything including meta data and watch progress of all users. Will there be any problems because of a wrong owner and group of the files and folders if I move or copy them?

Thank you @ChuckPa, I made that work. So with that docker run command I pulled PMS with the “plexpass” tag. I couldn’t find an explanation of the differences betwen the tags “latest”, “pexpass”, “public” and “beta”.
So “beta” is probably the beta channel that only Plex Pass users get. But where’s the difference to “plexpass” here? Also what’s the difference betwen “latest” and “public”?

yes.

plexpass = beta
latest = public

Ok, thanks.

My last questions before this topic can be closed:

  • I just read on reddit that “plexpass” performs an update check everytime the container gets (re-)started and updates PMS if there is an update. Is this correct?
  • And does the “plexpass” version of PMS still perform update checks inside PMS itself like the Synology app? I’m asking because I use watchtower to check and perform updates of my Docker containers every night. And I don’t need update checks inside PMS because of that.

PMS always performs an update check at startup.

PlexPass or Public – It is the same software. The only difference is your account.

Settings - Server - General allows you to set which updates to watch for.

Public Channel
-or-
Beta Channel
