What is NZBHydra2?

NZBHydra2 combines all your favourite Torrent and Usenet indexers into a single search site which then feeds your automation tools such as Sonarr and Radarr.

Let’s Begin

In this guide I will be taking you through the steps to download and setup NZBHydra2 in Docker on a Synology NAS.

In order to use this guide successfully you will need to complete the proceeding guide which will get your Docker, user setup.

• Step 2: Setting up a restricted Docker user

Downloading the container

Open up Docker within DSM and navigate to the ‘Registry’ tab, then search for ‘NZBHydra2’.

In the list of available containers select the one made by Linuxserver as shown below, right click on it and select ‘Download’ or click the button at the top of the window.

When the dialogue pops up asking you to choose a version, make sure you choose ‘Latest’ from the list.

You can check the status of the download over on the ‘Image’ tab, it will take a few minutes depending on the speed of your internet connection.

Setting up the container

Back in the ‘Image’ menu highlight the NZBHydra2 image and click on Launch. This will open up the setup wizard.

The first screen will ask how you want to set up the Docker network, to keep things simple we will be using the Docker Host option which means we will not need to set up any additional ports. Click Next once you have selected the option.

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 NZBHydra 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’

Volume Settings

We will now be specifying the directories where Hydra will store its configuration files.

Let’s create a folder for the configs, click on ‘Add Folder’ select the ‘docker’ share and create a new sub-folder called ‘hydra’ click on this folder and click ‘select’

Now add ‘/config’ to the Mount path box

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 the web interface via the IP of your NAS followed by the port 5076

e.g. 192.168.0.45:5076

Docker Compose

You can use the below code saved as hydra.yml in ‘/docker/hydra’ which you will need to create, this will do the entire process above in one quick command via SSH.

version: "3.8"
services:
  nzbhydra-linuxserver:
    image: linuxserver/nzbhydra2:latest
    container_name: nzbhydra2
    environment:
      - PUID=YOURPUID
      - PGID=YOURPGID
      - TZ=Europe/London
    volumes:
      - /volume1/docker/hydra:/config
    ports:
      - 5076:5076/tcp
    restart: unless-stopped

sudo docker-compose -f /volume1/docker/hydra/hydra.yml up -d --remove-orphans
