Why was this posted to HN? There is nothing new or original in the setup presented. People have been self-hosting all kinds of things on commodity hardware for decades, even things said to be "impossible" to self-host like email.
Also, nobody should be buying an (overpriced) Raspberry Pi for self-hosting, when used mini-PCs are faster, more reliable (no SD card, better cooling), and often cheaper.
Finally, I don't think you should use Proxmox in a home setting: too much abstraction, too much overhead (mainly memory). Use Docker where it makes sense, and deploy the rest bare metal.
It has similar vibes as the "I use Arch btw." t-shirt.
There's nothing new or original in a lot of things that get posted here. Reading about someone starting a journey provides an interesting catalyst for discussion. What they did right, what they did wrong, other things to try, or even just providing a push to someone else to also try.
I'll take my turn on the soapbox to say I hope people keep posting about their adventures and misadventures in trying something new. I'd much rather be reading that than seeing yet another post on LLM-based agentic startups or pelicans riding bicycles.
