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.

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

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
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

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"
services:
  linuxserver-radarr:
    image: linuxserver/radarr:latest
    container_name: radarr
    environment:
      - PUID=YOURUID
      - PGID=YOURGID
      - TZ=Your/Timezone
    volumes:
      - /volume1/data:/data
      - /volume1/docker/radarr:/config
    ports:
      - 7878:7878
    network_mode: synobridge
    restart: unless-stopped
sudo docker-compose -f /volume1/docker/radarr/radarr.yml up -d

    Good evening. I’ve been experiencing an issue with both Radarr & Sonarr. Everything works fine except final permissions on the downloads. Often they will show as just accessible by the docker user I created and “User” group, instead of inheriting permissions from my parent AV Data folder (where everything AV related resides), this means Plex etc doesn’t see them until I manually update the permissions in DSM. Anyone else seen this or any thoughts in how to resolve?

      Hey, if you are using the Plex package rather than Docker this is a known issue, it’s not permissions related it’s to do with the synoindex service not actually picking up the files existing (bizarre I know). A couple of users on Discord have enabled the Set Permissions option under Media Management to update the files permissions upon the moving them, this seems to trigger the service and Plex can see them. It’s worth doing a migration of Plex over to Docker, It’s fairly straight forward and removes the issue. I can talk you through on Discord.

      • Mr Stuart R Fagg Mr Stuart R Fagg

        Thanks for the reply and offer of help. I’m not sure it’s a synoindex issue as those that save with correct, inherited permissions are found by Plex straight away. Not got to the bottom of why some save ok and others don’t. I will read up a bit more on setting permissions in media management and will also have a think about moving Plex to docker. Cheers

    Could you add an upgrade flow? Should we just pull the new “latest” image?

    • Dr_Frankenstein Dr_Frankenstein

      Hey, see the left hand menu for a couple of ways to perform either manual or automatic upgrades.

    Error I am getting in Radarr:

    You are using docker; download client nzbget places downloads in /data/usenet/completed/Movies but this directory does not appear to exist inside the container. Review your remote path mappings and container volume settings.

    I followed steps 1 & 2 before installing the docker containers using YML. I included the environmental variables for PUID, GUID, and TZ. My volumes are mapped as well.

    What have I done wrong? It seems I can’t see my shares from within the containers.

    • Dr_Frankenstein Dr_Frankenstein

      Glad we sorted this on Discord. I am going to make sure all the compose sections line up for copy and pasting. FAWs coming soon as well to cover off all the basic settings.

      • Craig Craig

        I’m having this issue as well following the latest version of this guide. Can you let me know what’s going on and how to fix?

        • Dr_Frankenstein Dr_Frankenstein

          Are you able to reach out of Discord or via my contact page, it’s likely something you have set in the settings of Radarr.

        • Craig Craig

          Oops. I think it just needed me to actually create a folder in that folder called “Movies”. Seems fine now.

  4. do these tutorials still hold up in 2022, and do you need to set up a new container and user for every install?
    I’m new to this, does it show?
    thx upfront for the info 🙂

    • Dr_Frankenstein Dr_Frankenstein

      Hey all good to use, no need for a separate user for each container, we just use a single new user with restricted privileges now.

    awesome awesome awesome!!
    Great tutorial ounce again!
