I have been subscribed for a while because it seems like something I _would_ like, but I honestly still don't get it. It seems like a hobby driven by a deep reverence toward enterprise hardware and software, especially network-related, most of which is no longer in production. Is there more to it?
Ok, that's what I was missing, I think--I see that stuff as "advanced home networking" and less lab-like. But I do really enjoy it.
How do you manage with all the upgrading and maintenance? It seems like a simple distro upgrade could throw various stability-oriented subsystems like "photos of my family" into compete chaos.
That's the exact reason I stopped using that stuff. Nothing is worse than the roommate complaining about being unable to watch tv while the raid 5 rebuilds.
These lab environments are useful for studying and prepping for industry certification exams like the CCNA, LPIC, MCSE and so on.
That homelab sub has a big population of people who feel personal empowerment or hobby satisfaction as either the secondary or primary utility to exam prep. Some even to the complete exclusion of exam prep.
Depends, I just enjoy running my own server rack and self hosting a bunch of stuff. It's nice not having a dependency on third party cloud storage for example, I run my own "cloud storage". I also learned Kubernetes using my lab and it was a lot more interesting than if I had just deployed one using a cloud provider, bare metal is really cool. The amount of compute power + storage + memory that I have for my cluster would easily cost £300+ a month in the cloud.
I think the homelab community has people from one extreme (racks of servers) to the other (smaller servers like the TS140). All share a desire to host their own services and just have fun learning and doing.
First of all, it's a sense of enjoying to tinker, same as a lot of people do with Raspberry Pis or Arduinos. The challenge is partly why I'm a developer in the first place.
Secondly, when storing large amounts of data (> 20 TB) or running high powered systems, cloud hosting can become very expensive very fast, especially if you don't need 99.9999% reliability (although for anything important - 3 backups, 2 devices, 1 offsite). I bought a used xeon 6-core server with 24gb of ecc ram on ebay for around $400 a couple years ago, along with a half dozen 5TB HDDs.
It makes it easy and was a mostly one time cost to mess around with DNA algorithms, docker/k8s, media encoding, home automation, and more. I've been considering upgrading to use an SAS backplane next, but with commercial 8 and 10TB hard drives getting cheaper, I may never need to jump to more drives then I have now.
A quick wikipedia search says Solaris Containers date back to 2004 but Linux Containers "only" 2008. Unless you're lumping chroot jails under the "containers" header.
Yes, LXC (the author meant LXC for "LXE" I think; the ProxMox appliance believe currently uses KVM and LXC (Proxmox previously used OpenVZ for containers, but that (OpenVZ) has lost much of its Linux OS support)) has definitely been around longer than Docker. Docker originally used LXC as its container tech.
Are we really so far down the "cloud" rabbit hole that owning computer hardware is this perplexing? Many things you'd want to experiment with can be best done at home (home automation, media servers, SDR, etc), and I'd rather do this and run VMs for everything than have a rat's nest of RPi cables for every home-based project.
Very fun to read but may be too advanced to start with... is there a particular reason why I couldn't or should't run this on a regular core i7 7700k powered machine?
For home use, I'd say start with what you have. You can always upgrade later.
Power consumption is the biggest thing. For an always-on home server, you want something that sips as little power as possible. (Some of the Intel Avoton CPUs have a 17W TDP, compared to an i7 which can have a TDP anywhere between 65-150W.)
Outside that, the only other issue is going to be lack of ECC RAM. Whether that's needed for a home server is debatable. Many folks can get by fine without it.
Oh, and lack of lights-out management utilities. Which is convenient, especially in headless setups... but hardly required when the server is a few feet away.
As a third-world citizen, I'll have to wait like 15 years for the price of that hardware to come down and be rejected by the first-world before I can ever hope to run all that crap.
Till then I'll keep feeding the Google/NSA machine.
I second this. I have a Dell Poweredge R610 I got off ebay in a quiet cabinet in my computer room. You can get pretty beefy ones for $500, add your own drives. Mine has been running fine for the last 2.33 years.
Living in Bulgaria and having a pretty solid income (programmer) I can tell you the prices are rarely the problem by itself.
My current cart in Amazon is about $470. With shipping and handling the whole thing goes to almost $800.
We might as well go to the local flea markets and spend the afternoon asking people around for the same things because almost everybody outside the comfy zone of Amazon and eBay ends up paying almost double due to shipping + handling costs.

You only get updates for security-related stuff (and, IIRC, stuff-breaking bugs), which seldom break things.
Also, hosting a home media server allows for perfect 4k streaming regardless of bandwidth speeds and/or your home networks current load.
Serves as a hub for my home automation setup as well.
Lots of things, all fun!

It seems like most home lab folks run a lab to gain experience on platforms people actually use.

"You may have heard of Docker, well this is essentially the same thing, except it’s been around a bit longer."
... really?
Whereas Docker (https://en.wikipedia.org/wiki/Docker_(software)) was first released in 2013.
More seriously, people might set up home labs for a variety of reasons, ranging from practical to fun.

another secret is 'you don't need the latest', in fact, almost nobody needs the latest.
Shipping alone would cost 100USD at minimum.

It's also got a nice certificate authority wizard.
