Please note if you are using DSM7.2 or higher you should use the Container Manager version of this guide from the menu.
This guide has reached the end of its updates as most people are now on the latest DSM update - This guide is correct as of 08/12/2023 however no further updates will be added.
| Update | Date |

| Removed docker compose section as rarely used | 18/07/2023 |
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
- Step 1: Directory Setup Guide
- Step 2: Setting up a restricted Docker user
- Step 3: Setting up a Docker Bridge Network
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.
| Variable | Value |
|---|---|
| PUID | The UID you obtained in the user setup guide |
| PGID | The GID you obtained in the user setup guide |
| TZ | Your timezone wikipedia.org/wiki/List_of_tz_database_time_zones |
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/Folder | Mount path |
|---|---|
| docker/radarr | /config |
| data | /data |
Click Next to move to the final screen.
Summary
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
e.g., 192.168.0.40:7878
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.
| App | Root Folder |
|---|---|
| Radarr | /data/media/movies |
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 http://172.20.0.1 which is the IP of the ‘synobridge’ gateway.

I followed all your steps but I’m unable to connect through Firefox. The container is running in docker and I’m connecting to the right port in my browser. When I try to access it Firefox just shows me this: https://imgur.com/a/ntunCeo
What can I do to access radarr?
Hey, double check you specified the ports correctly. If its not that can you reach out on Discord or my contact page.
Hi,
I folllowed your guides to install sabnzbd, sonarr and radaar.
I got no problem for sabnzbd and sonaar.
However radaar is not working.
When the container starts I get the following error :
[Error] DownloadClientRootFolderCheck: Unknown error occured in DownloadClientRootFolderCheck HealthCheck
with the exception:
[v4.1.0.6175] System.Net.Http.HttpRequestException: Connection refused (localhost:8080)
I did’nt find any solution that I understand on internet.
Please, could tell me how to fix that please ?
Double check you have your settings correct including the volume/mounts and also the PUID/PGID as a starter. If that fails delete the container and any contents of /docker/radarr and try the setup again.
i have setup my radarr with the old files. And also sonarr. But i seem to have a problem with Radarr, when i look into my docker file there are no maps in my radarr, where there are a lot in my sonarr. I recently downloaded the sonarr and radarr companion from google play store and i can perfectly get to my tv series, but when i give in the ip and API to my radarr it doesn’t find anything. So i guess this has to do with the lack of maps and info in my radarr map. Do you have a solution for this, or should i delete the whole setup and start from scratch? thx upfront
Hey, ping me an email I can help out. Could do with some screenshots of your volumes you mapped for each container and where your old movies etc reside.
The contact page is top left of my site or drfranky at drfrankenstein.co.uk
i have send you a mail as requested, don’t know if you got it
Ugh…I know this is going to be a dumb question, but it has me stumped, so here goes.
Is there any trick to access Radarr after it is setup? I followed along with every setup step here. But when it says “You should now be able to access Radarr via the IP of your NAS followed by the port 7878”, and I try that, I get the message of “Safari can’t open the page because Safari can’t connect to the server”.
I am connected to the NAS already on a different tab (IP address:5001), so I know it can connect, so I must be typing something in wrong.
Nevermind, think I figured it out 😛
Hi – I have the same issue, would you mind sharing how you resolved the problem? Many thanks.
Hi Ed
Do you have the Synology firewall turned on and blocking all ports? If so you will need to open the port up in order to access the UI.
First of all, thanks for the guides! They are really helpful.
I have an issue that I am suspecting has to do with permissions. I followed your guide to create a dockerlimited user and assigned permissions to the files/folders in the volumes that I needed.
Radarr is the only container that I am having issues with. When I look through the terminal, I am able to see everything in the folder and even create files. I verified through another machine and user that all the permissions are ok. However, when I add this folder, Radarr is not picking up any of the files. Any ideas?
Hey Rob, I could do with some extra info and probably some screenshots. Can you reach out via the Discord channel or via my Contact Page top left of the site. I will need to see the volume settings for Radarr as a starter and what folder you are mounting..
Hey, thanks for the quick reply, but I figured out my problem. Permissions were fine, its just I either misread or assumed that Radarr was able to detect loose files. Evidently they must all be in separate folders to be detected.
