Guide re-written and updated with DSM7 screenshots01/08/2021

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 two 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 now see the initial setup screen, you can change the name of the container, we are not going to change the resource limitations.

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 Radarr 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 Radarr will store its configuration files and where to find our media and downloads.

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

This first folder will map to /config in the mount path section.

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

In the Mount path section for this folder enter ‘/data’

Your mounts should now look like the table/screenshot below.

File/FolderMount path
docker/radarr/config
data/data

Network

We are not going to be specifying specific ports for Radarr 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.

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

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: "3.2"
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
    network_mode: host
    restart: unless-stopped
sudo docker-compose -f /volume1/docker/radarr/radarr.yml up -d

  1. Great guide. There is a path error in your docker-compose line. Should be

    /volume1/docker/radarr/radarr.yml

    • Dr_Frankenstein Dr_Frankenstein

      Good spot! Fixed 🙂

  2. Hey, thanks for the tutorial that was easy to reproduce. However when i access to the radarr app I have this error message
    “You are using docker; download client Sabnzdb places downloads in /config/Downloads/complete but this directory does not appear to exist inside the container. Review your remote path mappings and container volume settings.”

    Any clu ?
    Regards

      • hey many thanks for the reply.

        I noticed after that i missed to update the folder path in Sabnzdb so I changed it according to your great tutorial but still i´m not able to download because Radarr requests me to add a path and i cannot do it.

        I go to settings/mediamanagement and try to add a root path but when I click on OK the path is not displayed. Even if i´m not sure about which one to enter.

        In settings/downloadclients is any mapping to udpate also ?

        Many thanks in advance

    Hello

    Fabulous writeups Dr_Frankenstein! Really helped get an idea of how to get this installed and setup. I was just wondering if you or the others are getting error messages in Radarr that says. “Download client NZBGet places downloads in the root folder /path/blah/blah. You should not download to a root folder.” I am getting this error in Sonarr as well

    Thank you

      • Dr_Frankenstein Dr_Frankenstein
