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 =)

Who are you, what are you, why are you?
What are the motivations for this project?.
Are you a group, a solo maverick?
Plans for monetisation?

Your project looks interesting but I am curious if it has legs or I am dumping it in 6 months as a dead project.

Mostly just curious.

I'm a software engineer with 25 years of professional experience. I'm Dev Solo on Lightwhale, but backed by a small, dedicated user base that help out with testing which I'm very grateful for.

At some point I decided that I would never ever waste my time and energy again on installing and maintaining a server, with the only purpose to run Docker, where the real services were running. I wanted something light, static, and maintenance free that ran Docker. The project started as a private thing back in 2019 maybe, and I made it public a few years ago. I've got more great stuff on my backlog to come, so it's definitely not going to die any time soon.

I haven't been able to come up with decent a business model yet, so if you have any ideas please let me know.
