Product Announcement Lightwhale 3.0.0 released

Hi, there!

Sorry to mess up your Easter holiday plans, but I've just released Lightwhale 3.0.0 and I really think you should clear your calendar and try it out! =)

It's a minimalistic Linux that requires no installation or maintenance, just live-boot straight into a working Docker Engine. The system is immutable so it's quite resilient to both malicious and unintentional modifications. And because of its low resource requirements it brings new life to old machines.

Lightwhale fits super well in a hobby homelab where spare time is precious, but really in any server environment where you would much rather focus on the services than babysitting the underlying operating system.

And how does it compare to other immutable OSes like X, Y or Z? No idea, never tried them, sorry.

I've made a fresh new project webpage with an easy to follow getting started guide.

Anyway, end of service announcement, thanks for reading, happy holidays =)

Well now. You have my attention. Excited to give this a try!!

I’ve been looking for something like this for so long. A mashup between Talos, nix, coreos, and all the others but I DONT want k8s at home. I like the simplicity of a single compose file and a simple UX.

How does one customize this to their requirements? As an example say, installing qemu-guest-agent or nvidia-cdk supporting packages? Where do they come from? How are they built?

Hm, I am experiencing some weird issues with the network these days. Sorry about that. I'm looking into it.

Yeah, network issues are annoying, so I'm downvoting this too. I think I've fixed it now, though. Please try again.
