Plex in Docker on a Synology NAS (No Hardware Transcoding)

UpdateDate
New guide released06/12/2021

In this guide I am going to take you through the setup of Plex in Docker.

Do I need Hardware Transcoding?

The version of this guide you follow will depend on whether you want hardware transcoding, this is available to Plex Pass holders and requires your Synology CPU to have Intel Quick Sync capabilities.

Generally, if you are only using Plex at home with devices that can direct play your media you likely won’t need this. However, if you have users that share your server outside your household, or plan on streaming to mobile devices you will want hardware transcoding as this will speed up the process of changing media between codecs and resolutions quickly.

You can find the hardware transcoding guide here, if you want the standard setup continue on below…

The Standard Guide

In order to use this guide successfully you will need to complete the two proceeding guides which will get your folder structure and Docker, user setup.

Downloading the Plex Image

Open up Docker within DSM and navigate to the ‘Registry’ tab, then search for ‘Plex’.

In the list of available containers select the one made by Linuxserver as shown below, right click on it and select ‘Download’ or click the button at the top of the window.

Linux Server Version

When the dialogue pops up asking you to choose a version, make sure you choose ‘Latest’ from the list.

The Latest tag means when ever you update the container it will grab the latest version

You can check the status of the download over on the ‘Image’ tab, it will take a few minutes depending on the speed of your internet connection.

Setting up the container

In Docker click on the ‘Image’ tab, in the list of your containers select the ‘Linuxserver Plex’ image and click on ‘Launch’

You will now see the initial setup screen, if you want to you can change the name of the container to something else.

If you are using a number of services on a machine with a limited amount of memory or lower powered CPU you can also set up resource limitations, but this is generally not required.

You will also notice a Configure capabilities button — don’t change anything in here!

Next up we are going to click on the ‘Advanced Settings’ button, this will take you to a new window with a number of tabs which we are going to work through.

On the first tab enable ‘Auto Restart’ this will ensure Plex will automatically start up whenever you reboot your NAS.

Volumes / Mounts

We can now move onto the ‘Volume’ tab in which we will be specifying the directories where Plex will store its configuration files and where to find our media.

Click on ‘Add Folder’ then select the ‘docker’ folder and create a new sub-folder called ‘plex’ select this folder and click ‘select’

Now add ‘/config’ to the Mount path box

Click Add Folder again and this time select the top level ‘data’ folder and click Select.

You will now enter ‘/data’ into the ‘Mount path’ box

Network

We are not going to be specifying specific ports for Plex to use as we want to keep things simple, tick the ‘Use the same network as Docker Host’

Links / Port Settings

You do not need to set up anything on these tabs.

Environment Variables (PGID,  PUID and Timezone)

Next we are going to set up a couple of environment variables that docker will use to allow the container access to our files and folders and also to tell it where we live in the world.

Click the Add button, and fill in the following details as per the table/screenshot, you will need to do one at a time.

variableValue
PUIDThe UID you obtained in the user setup guide
PGIDThe GID you obtained in the user setup guide
TZYour timezone wikipedia.org/wiki/List_of_tz_database_time_zones

Almost Done

You have now completed the setup of the container.

Click on Apply to move back to the initial settings screen and then click next, you will be shown an overall summary of the settings we have specified, this is a good time to double-check everything is correct. Finally, click on Done and the container should start to boot.

After a few minutes you should be able to access the server and go through the Plex setup by going to the IP of your NAS in your browser followed by port 32400/web/

e.g 192.168.0.45:32400/web/

You will be asked to sign in or sign up for an account if you don’t have one already.

You should now be able to add your media which will be in the /data folder within Plex

We mounted everything to /media, so you can find your media in that folder and add each of your Movie / TV libraries

You have now completed the setup!

    Just to be clear: I have a Synology 1621+ with an AMD Ryzen V1500B CPU, therefore I should use the non-hardware transcoding installation.

      Hey, To be honest it would be great if you could test it please, I don’t have an AMD based machine to try it. Based on some google searches it should work. If so I can update the guide based on your feedback.

      If you have Discord it would be great to let us know on there as well.
