5 Cool Apps for your Unraid NAS

I’ve got a (now four-year-old) Unraid NAS called Fox and I’m a huge fan. I particularly love the fact that Unraid can work not only as a NAS, but also as a fully-fledged Docker appliance, enabling me to easily install and maintain all manner of applications.

A cube-shaped black computer sits next to a battery pack on a laminated floor. A sign has been left atop it, reading "Caution: Generator connected to this installation."
There isn’t really a generator attached to Fox, just a UPS battery backup. The sign was liberated from our shonky home electrical system.

I was chatting this week to a colleague who was considering getting a similar setup, and he seemed to be taking notes of things he might like to install, once he’s got one. So I figured I’d round up five of my favourite things to install on an Unraid NAS that:

  1. Don’t require any third-party accounts (low dependencies),
  2. Don’t need any kind of high-powered hardware (low specs), and
  3. Provide value with very little set up (low learning curve).
Dan, his finger to his lips and his laptop on his knees, makes a "shush" action. A coworker can be seen working behind him.
It’d have been cooler if I’d have secretly written this blog post while sitting alongside said colleague (shh!). But sadly it had to wait until I was home.

Here we go:

Syncthing

I’ve been raving about Syncthing for years. If I had an “everyday carry” list of applications, it’d be high on that list.

Syncthing’s just an awesome piece of set-and-forget software that facilitates file synchronisation between all of your devices and can also form part of a backup strategy.

Here’s the skinny: you install Syncthing on several devices, then give each the identification key of another to pair them. Now you can add folders on each and “share” them with the others, and the two are kept in-sync. There’s lots of options for power users, but just as a starting point you can use this to:

  • Manage the photos on your phone and push copies to your desktop whenever you’re home (like your favourite cloud photo sync service, but selfhosted).
  • Keep your Obsidian notes in-sync between all your devices (normally costs $4/month).1
  • Get a copy of the documents from all your devices onto your NAS, for backup purposes (note that sync’ing alone, even with versioning enabled, is not a good backup: the idea is that you run an actual backup from your NAS!).

Huginn

You know IFTTT? Zapier? Services that help you to “automate” things based on inputs and outputs. Huginn’s like that, but selfhosted. Also: more-powerful.

When we first started looking for a dog to adopt (y’know, before we got this derper), I set up Huginn watchers to monitor the websites of several rescue centres, filter them by some of our criteria, and push the results to us in real-time on Slack, giving us an edge over other prospective puppy-parents.

The learning curve is steeper than anything else on this list, and I almost didn’t include it for that reason alone. But once you’ve learned your way around its idiosyncrasies and dipped your toe into the more-advanced Javascript-powered magic it can do, you really begin to unlock its potential.

It couples well with Home Assistant, if that’s your jam. But even without it, you can find yourself automating things you never expected to.

FreshRSS

I’ve written a lot about how and why FreshRSS continues to be my favourite RSS reader. But you know what’s even better than an awesome RSS reader? An awesome selfhosted RSS reader!

Yes, I know I have a lot of “unread” items. That’s fine, and I can tell you why.

Many of these suggested apps benefit well from you exposing them to the open Web rather than just running them on your LAN, and an RSS reader is probably the best example (you want to read your news feeds when you’re out and about, right?). What you need for that is a reverse proxy, and there are lots of guides to doing it super-easily, even if you’re not on a static IP address.2. Alternatively you can just VPN in to your home: your router might be able to arrange this, or else Unraid can do it for you!

Open Trashmail

You know how sometimes you need to give somebody your email address but you don’t actually want to. Like: sure, I’d like you to email me a verification code for this download, but I don’t trust you not to spam me later! What you need is a disposable email address.3

How do you feel about having infinite email addresses that you can make up on-demand (without even having access to a computer), subscribe to by RSS, and never have to see unless you specifically want to.

You just need to install Open Trashmail, point the MX records of a few domain names or subdomains (you’ve got some spare domain names lying around, right? if not; they’re pretty cheap…) at it, and it will now accept email to any address on those domains. You can make up addresses off the top of your head, even away from an Internet connection when using a paper-based form, and they work. You can check them later if you want to… or ignore them forever.

Couple it with an RSS reader, or Huginn, or Slack, and you can get a notification or take some action when an email arrives!

  • Need to give that escape room your email address to get a copy of your “team photo”? Give them a throwaway, pick up the picture when you get home, and then forget you ever gave it to them.
  • Company give you a freebie on your birthday if you sign up their mailing list? Sign up 366 times with them and write a Huginn workflow that puts “today’s” promo code into your Obsidian notetaking app (Sync’d over Syncthing) but filters out everything else.
  • Suspect some organisation is selling your email address on to third parties? Give them a unique email address that you only give to them and catch them in a honeypot.

YOURLS

Finally: a URL shortener. The Internet’s got lots of them, but they’re all at the mercy of somebody else (potentially somebody in a country that might not be very-friendly with yours…).

YOURLS screenshot (Your Own URL Shortener).
It isn’t pretty, but… it doesn’t need to be! Nobody actually sees the admin interface except you anyway.

Plus, it’s just kinda cool to be able to brand your shortlinks with your own name, right? If you follow only one link from this post, let it be to watch this video that helps explain why this is important: danq.link/url-shortener-highlights.

I run many, many other Docker containers and virtual machines on my NAS. These five aren’t even the “top five” that I use… they’re just five that are great starters because they’re easy and pack a lot of joy into their learning curve.

And if your NAS can’t do all the above… consider Unraid for your next NAS!

Footnotes

1 I wrote the beginnings of this post on my phone while in the Channel Tunnel and then carried on using my desktop computer once I was home. Sync is magic.

2 I can’t share or recommend one reverse proxy guide in particular because I set my own up because I can configure Nginx in my sleep, but I did a quick search and found several that all look good so I imagine you can do the same. You don’t have to do it on day one, though!

3 Obviously there are lots of approachable to on-demand disposable email addresses, including the venerable “plus sign in a GMail address” trick, but Open Trashmail is just… better for many cases.

Installing Listmonk on Unraid

I wanted to play about with Listmonk and it’s available as a Docker image, so I figured I’d just install it on my Unraid box. It doesn’t have a recipe in Community Apps but it’s not usually hard to reverse-engineer an official installation guide into something that “just works” on Unraid. After a first attempt failed, I looked around for a quick how-to guide online and mostly found… a mixture of people similarly failing to get it working or else having a kindly stranger offer to help… but not on the open Web where the rest of us can benefit from their knowledge. Sigh.

So I resolved that when I figured it out, I’d document the steps so that the next person after me can have an easier job of it.

Installing Listmonk on Unraid

  1. Install Postgres if you don’t have it already. I used the postgresql15 image from Community Apps.
  2. Set up a role and database. To do this, log in to your Postgres database using your favourite Postgres client and run, for example:
    CREATE USER listmonk WITH LOGIN PASSWORD 'my-listmonk-db-password';
    CREATE DATABASE listmonk OWNER listmonk;
  3. Create a Listmonk configuration file. I created a listmonk share and put it in there, calling it /listmonk/config.toml, but anywhere on your Unraid server will do. There’s a sample configuration in the repository. You’ll probably want to change:
    • [app] address: change to 0.0.0.0:9000 to listen on all interfaces so you can access it from elsewhere on your network (might not be needed if you intend to proxy with a host-networked reverse proxy server)
    • [app] admin_username / admin_password: obviously change these – this is how you’ll log in to your Listmonk system
    • [db] host: if your Postgres container and/or Listmonk container is running in bridged networking mode rather than host networking mode, you’ll need to change this to the name or IP address of your Postgres server
    • [db] password: set to the password you chose for the listmonk user on your Postgres server
  4. Add a Listmonk container. In Unraid, on the Docker tab, click the Add Container button. A minimal configuration might look like this:
    • Name: Listmonk
    • Repository: listmonk/listmonk:latest
    • Network Type: consider using Host to simplify your [db] setup, above.
    • Add a Port with Name: HTTP and Host Port: 9000. Then fill in 9000 as the value (or whatever port you want to run Listmonk on)
    • Add a Path with Name: Config and Container Path: /listmonk/config.toml. Set the Host Path to wherever you put the Listmonk configuration file, e.g. /mnt/user/listmonk/config.toml.
  5. Start the Listmonk container and watch it stop. When you click “Apply” the container will start, run for a few seconds, and then stop. If you want, look at the logs and you’ll see what the problem is: it needs to be started in a different way in order to set up the database. Instead, what we’ll do is spin up a new Listmonk container just for that purpose (and then throw it away).
  6. Start Listmonk in “install” mode. SSH into your Unraid server itself and run, e.g.
    docker run --rm -ti --net='host' -e TZ="UTC" -v '/mnt/user/listmonk/config.toml':'/listmonk/config.toml':'rw' listmonk/listmonk:latest ./listmonk -- --install
    Substitute /mnt/user/listmonk/config.toml for whatever path your configuration file is at, if applicable. You’ll be prompted with the messages “** first time installation **”, “** IMPORTANT: This will wipe existing listmonk tables and types in the DB ‘listmonk’ **”, and then asked “continue (y/N)?”. Press “y” and the installation will complete.
  7. Start the Listmonk container again. This time it’ll stay running and you’ll be able to access the Web interface via e.g. https://your-unraid-server:9000/

Hope that helps somebody!
