This needs a companion guide about how to set up the host machine. Which Linux distro to choose, how to set it up / harden it, nftables / firewall, public key login, etc.
If anyone has one handy, I'd appreciate a link.

Having my own personal CloudBox has allowed me to experiment and fail fast. I am ahead in experience and knowledge than the rest of my team as a result. I have a tool they do not. I realize it would be better if we all had a tool like this.
So that’s the pitch, a single node “cloud in a box’, the CloudBox for IT students or professionals to learn any aspect of IT.
Now I just need lots more time to actually turn my prototype into a product.
There's flatcar and k3os and fedora coreos and talos and lokomotive. There are maybe a dozen others as well, but those are the ones I know something about.
The real problem is that the orchestration of PXE boot, DHCP, name services, server registration, cluster bootstrapping, while simultaneously building a light distribution that makes the right calls on persistence, security, etc. is just *really hard*.
I took at a stab at it myself (failed startup) and have a custom distribution based on alpine, but the amount of work to go from there to everything is so large that it's tough to take on if you're small (and there is the constant desire to go enterprise because of the money)
I'd be satisfied with a home-user-oriented manual tutorial, like install Debian with these packages, a nftables setup that firewalls everything but these 3 ports, how to setup auto-update, turn off root & password-only logins, and general things to be reasonably secure; as well as tips for on-going maintenance and so on.
