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


Key Settings and FAQ

Now you have set up Radarr there are some key settings you will need to set as these often catch new users out. I will add more as they come up.

Media Management / Root Folders (Settings>Media Management)

Radarr refers to the place(s) you keep your movies as Root Folders. These are where Radarr will ultimately move your movies to once they finish downloading.

AppRoot Folder

Download Clients (Settings > Download Clients>Remote Path Mappings)

While most of the settings on this page are self-explanatory something that has caught people out if the Remote Path Mappings setting. If you are hosting all your services on the same NAS do not add any settings here.

I can’t get Radarr to Connect to my Download Client!

When setting up your preferred download client or Prowlarr etc. Usually you will use the IP of your NAS, however if for whatever reason this is not working you can use which is the IP of the ‘synobridge’ gateway.

    thanks for the great guides. Having basic knowledge of docker, you saved me a bit of time researching this for synology.
    sent you some BTC for coffee.

    Hey, thanks for all of your help with this site! I was able to successfully setup qBittorrent with GlueTUN and my torrents download successfully into the ‘/data/torrents/completed’ folder. I also have Radarr installed and running and it is able to see all of the movies I manually moved to the root folder ‘/data/media/movies’. However Radarr doesn’t seem to be moving any of the completed torrents from the ‘/completed’ folder into the ‘/movies’ folder. Do you have screenshots or more details on how you have your Radarr setup? Thanks again, really appreciate everything you’ve done for us!

    For some reason my Radarr wasn’t seeing my data folders when I went to set up the root. I replaced the docker compose ‘/volume1/data:/data’ with ‘/volume1/data/:/data’ and that seemed to fix the issue. Not sure if that was just an issue for me or not, but I thought I’d point it out to see if it helps others. Thanks for all these guides!

    I’m getting “You are using docker; download client NZB places downloads in /downloads/completed/Movies but this directory does not appear to exist inside the container. Review your remote path mappings and container volume settings.”

      Hey, seen you post on Discord this might be a temporary error message from just before you change your file paths in NZBget

    yo, i havent been able to update radarr via docker for last couple months. i go with the top search result and get a time out everytime. any clue?

    sonarr / tautulli etc…update just fine.

      Hey, this sounds like an odd DNS issue, try overriding the one you are using (assuming your ISPs) Open Control Panel > Network > General > Manually Configure DNS Server. Then use something like Quad 9 ( and a secondary like Cloudflare (

        so i just installed the watchtower container and it updated radarr successfully that way. thanks anyway!
