What is Radarr?

Radarr is used to search, download and organise your Movies in conjunction with your preferred Usenet or Torrent downloaders and indexers.

Let’s Begin

In this guide I will take you through the steps to get Radarr up and running in Docker.

In order for you to successfully use this guide please complete the three preceding guides

Downloading the Radarr Image

Open up Docker within DSM and navigate to the ‘Registry’ tab and search for ‘Radarr’. In the list of available containers select the one made by Linuxserver as shown below then click ‘Download’.

The pop-up box will ask which version you want to download, make sure you choose ‘Latest’ from the list of available versions.

You can check the status of the download over on the ‘Image’ tab.

Setting up the container

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

You will be greeted with the Network screen, we will be using the ‘synobridge’ network we created earlier select it from the list and click Next.

General Settings

Next you will be greeted with the General Settings screen, this is where you can start specifying some of your preferences.

You can change the name of the container to anything you like, and you may want to enable Auto Restart as this will ensure Radarr starts automatically if you reboot your NAS.

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.

Environment (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.

PUIDThe UID you obtained in the user setup guide
PGIDThe GID you obtained in the user setup guide
TZYour timezone

Links / Execution Command

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

Press ‘Save’ to go back to the initial setup screen, then press ‘Next’

Port Settings

We won’t be changing any of the ports the container uses. You can repeat the ones shown on the right side of the settings page ‘Container Port’ onto the left side ‘Local Port’ once you have done this press ‘Next’.

Volume Settings

We will now be specifying the directories where Radarr will store its configuration files and where to find our media and downloads.

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

Repeat this process to add the /data folder.

You will now add the below settings into the ‘Mount path’ section

File/FolderMount path

Click Next to move to the final screen.


You have now completed the setup of the container.

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.

You should now be able to access Radarr via the IP of your NAS followed by the port 7878


Make sure you check out page 2 of this guide that covers some common basic settings.

Docker Compose

You can use the below code saved as radarr.yml in the ‘/docker/radarr’ share, this will do the entire process above in one quick command via SSH. Ensure you change the variables to your own.

version: "3.8"
    image: linuxserver/radarr:latest
    container_name: radarr
      - TZ=Your/Timezone
      - /volume1/data:/data
      - /volume1/docker/radarr:/config
      - 7878:7878
    network_mode: synobridge
    restart: unless-stopped
sudo docker-compose -f /volume1/docker/radarr/radarr.yml up -d

      I am using an older 1815+ with 16GB of RAM, Synology have an official page showing the models supporting Docker. So it depends on what your use case is going to be on which model would be best.

  1. Jose Jose

    I cannot import my movies it just shows the file structure for the linux server files. Any idea?

      Looks like you got caught in the Spam filter, do you sort this out?

      • chas chas

        This has happend to me also.

  2. Christopher C Walker Christopher C Walker

    so what is the root folder path you set in the actual Radarr application?

    it is /data/media, data/usenet?

    • Dr_Frankenstein Dr_Frankenstein

      Within Radarr your route path will be /data/media/movies

  3. Simon Simon

    Thank you for all these guides, they have been extremely helpful. I seem to be struggling at the last hurdle though. My Radarr install is throwing the following error:

    Download client SABnzbd places downloads in /data/usenet/completed but Radarr cannot see this directory.

    How do I get past this?

    • Dr_Frankenstein Dr_Frankenstein

      double check your Radarr mount it should be /data to /data meaning it will have access to that directory.

      • Simon Simon

        Thanks for the quick response. Turns out the config needed to be the same as for SABnzbd (data/usenet – /data/usenet).

        • Dr_Frankenstein Dr_Frankenstein

          If you have just /data/usenet passed into Radarr it won’t have any access to your media in /data/media, /data should work

          • Simon Simon

            OK, I have to apologise. I was obviously having a real blonde moment. I still had the SynoCommunity package running as well and was trying to update this config on a that instance which was running on a different port. All good now. Thanks again.

          • Dr_Frankenstein Dr_Frankenstein

            Lol no problem

  4. Thanks for these docker guides! Been a great help getting me off of the Synology community packages.

    • Dr_Frankenstein Dr_Frankenstein

      No probs glad they are useful
