I just learned about the whole homelab thing a week ago; it's a much deeper rabbit hole than I expected. I'm planning to setup ProxMox today for the first time in fact and retire my Ubuntu Server setup running on a NUC that's been serving me well for last couple years. I hadn't heard about mealie yet, but sounds like a great one to install.

Ubuntu Server setup running on a NUC that's been serving me well

In my book, that’s a homelab, it's just a small one (an efficient one?...)

I've recently learned that "homelab" is a specific thing meaning you run certain software (like Proxmox), and not a generic term for running a 'server lab' at home.

Wait, what?

Surely people have had ‘homelabs’ for longer than VMs and container have been mainstream?

I went in thinking that maybe there's something to learn for my grand total of 1 ThinkCentre M910q "homelab", but this author's setup is on another league, I'm sure closer (or surpassing) the needs of a small/medium company!

Here is an actual another league if you are curious about it https://youtu.be/-b3t37SIyBs

My most recent learning - DDR4 ECC UDIMMs are comically expensive.

You seem knowledgeable so you may already know, but it's worth looking at the x86 mini PCs. Performance per watt has gotten pretty close on the newer low power CPUs (e.g. N150, unsure what AMD's line for that is), and performance per $ spent on hardware is way higher. I'm seeing 8GB Pi 5s with a power supply and no SD card for $100; you can get an N150 mini PC with 16GB of RAM and 500GB SSD pre-installed for like $160. Double the RAM, double the CPU performance, and comes with an SSD.

Imo, Raspberry Pis haven't been cost competitive general compute devices for a while now unless you want GPIO pins.

You should definitely try mealie yes. On top of a good way to host your own recipes, the entire thing just feels...really well put together?

I'm not even using the features beyond the recipes yet, but i'm already very happy that i can migrate my recipes from google docs to over there

I have Proxmox running on top of a clean Debian install on my NUC, I wanted to allow Plex to use the hardware decoding and it got a bit funny trying to do that with Plex running in a VM, so it runs on the host and I use VMs for other stuff

It's very easy to do this with LXC containers in Proxmox now, as passing devices to a container is now possible from the UI.

Earlier quoted context omitted.

It's a neat chip but I couldn't bring myself to spend in excess of the price of the UPS ($439.00 for RMCARD at time of writing). I ended up hooking my UPS via USB to my existing home server via NUT and it's been working well.

It is a little hefty for a homelab-level setup, but the impressive bit to me is that they've kept compatibility with it longer than we've replaced UPSes at work (it looks like the RMCARD205 and 305 were introduced in 2018), so instead of paying for that hardware built into each unit, the RMCARD has been a one-time purchase we can bring from unit to unit.

APC UPSes that support their network management card add in - then the cards can frequently be purchased on eBay for $30-$100, you have to make sure the UPS supports the card, but they are excellent. Model numbers like ap9631 (if i recall). I run about 10 of them across different locations and they work great , some of them for 8+ years now. ( about a year ago when I got a new ups, Apc still offered the older firmware for download, however after a certain FW version it started going to a cloud subscription model - so be sure to keep the old firmware. If you’re worried about the firm or not being updated on the non-cloud version, just be sure to vlan/firewall control access to them which you should be doing anyway)

Can somebody explain the whole proxmox thing? I haven’t used it, I use k3s. I don’t get why people use VMs for stuff when there’s docker. Thanks!

it's so you can have a machine to run docker on, basically. especially useful if you want multiple of those, and also helpful if you don't want one of them anymore.

"Why would I need virtualization when I have Kubernetes".. sounds like a someone who has never had to update the K8s control plane and had everything go completely wrong. If it happens to you, you will be begging for an HVM with real snapshots.

Yeah have a collection of minipc - they are indeed great. This build was more NAS focused. 9x SATA SSD and 6x NVME...minipcs just don't have the connectivity for that sort of thing

>Imo, Raspberry Pis haven't been cost competitive general compute devices for a while now unless you want GPIO pins.

I have a bunch of rasp 4Bs that I'll use for a k8s HA control plane but yeah outside of that they're not idea. Especially with the fragility of SD card instead of nvme (unless you buy the silly HAT thing).
