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.
You can conceptualize the "my program + the OS" as a single program. It's not a pretty picture. Lots of global mutable state. Also it randomly modifies itself?
The whole point of Docker appears to be "I just want to run my program", in the least painful way possible. Immutable Linux extends the "lean in the direction of sanity" idea.
And then there's "it turns out 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 technically the right answer, except... now I'm a kernel developer? Maybe that's the least bad option, long term...
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'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?
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?
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.
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.
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

I've long since thrown everything with a user count > 1 out.
Kudos to the great project!

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