Show HN: I've built a nice home server OS

ohai!

I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers.

It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon.

If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide.

In any event, have a nice day! =)

I like the idea of something like this for swarm mode clusters; not sure if you’re focused on the home server aspect exclusively, but I’ll be following along.

Kudos to the great project!

Zta77•1h ago
Thanks! I'm only announcing it for home servers because that's where most people are willing to try it out. But Lightwhale is already running in production, and it makes an excellent Swarm cluster.

So I’ve just set up my home server with Ubuntu server, installed docker with one line and I’m off to the races. What’s different/ exactly the value prop of this? You mention maintenance, of what exactly? Is your server a slimmed down version to run on less powerful hardware? Genuinely curious as I’m new to setting up a home server so seeing how this would benefit me.
zackify•1h ago
I do the same thing. Being immutable is supposed to be great for updates. New image version and if there's a problem you can boot back to the last version no problem.

But functionally, like you I find Ubuntu server fine. I run apt update and upgrade a couple times a year and its local only with tailscale access.

I find these immutable OS's really nice on laptop or desktop. The home directory is the only thing that can be written to so the OS is supposed to be more stable and can't break easily

happyopossum•1h ago
As long as there is software, you cannot shortcut the need for maintenance. Nothing is bug free, and telling people they will never need to upgrade/patch/maintain a system is a well-paved path to compromised systems.

I've been telling people this for years. Yes, you can self host, but you'll end up with a SLA on your spare time as well as you working hours.

I've long since thrown everything with a user count > 1 out.

darknavi•1h ago
I'm a novice in this space I think. I've self-hosted for over a decade and around 2019 I moved over to Unraid, which is generally pretty visual (web portal or configuring and doing maintenance). I find the web portal very easy. How does one interact with your home server OS? I assume it's all via terminal because there are no pictures on the website?

This is a Linux distro, not an OS!
logic-designer•53m ago
did you say anywhere what package manager it uses (couldnt find that info on the website)
gardnr•27m ago
Looks like it may not have a package manager like apt or dnf:

> Can you please add wget, nano, $my_fav_app_omg_i_love_it to the root filesystem?

> No, not likely.

I am guessing the way to use software not already in the image is to use `docker run`.

mkl•8m ago
It's immutable and you can't install packages, just docker containers.
coreyburnsdev•23m ago
can't imagine a world in which I'd download a little known distro to put on my home network and use as a server. also, doesn't fedora already have something like this already?
andai•1m ago
This is relevant to what I have been learning about recently!

I'm getting ready to launch an online game and I'm dealing with "how do I just run my game server on dozens of boxes without dealing with linux stuff".

I don't really have an answer yet (leaning into "just get one really powerful box" lol), but my investigation into the problem so far has been pretty interesting.

The whole point of Docker appears to be "I just want to run the thing." The least painful way we found so far of getting the OS out of the way as much as possible. Immutable Linux sits below that.

And then there's "the OS solves problems I don't have, while creating many new problems", which leads to Unikernels. Fun stuff ;)

In a perfect world, I wouldn't need the OS at all. Docker gives me two Linuxes to worry about! Unikernels are the right answer, except... now I'm a kernel developer?

(Maybe that's the least bad option, long term...)
