KISS

The more complicated the machine the more chances for failure.

Remote management plus bare metal just works, it's very simple, and you get the maximum out of the hardware.

Depending on your use case that could be very important

I consider them unnecessary layers of abstraction. Why do I need to fiddle with Docker Compose to install Immich, Vaultwarden etc.? Wouldn't it be simpler if I could just run sudo apt install immich vaultwarden, just like I can do sudo apt install qbittorrent-nox today? I don't think there's anything that prohibits them from running on the same bare metal, actually I think they'd both run as well as in Docker (if not better because of lack of overhead)!

Here’s my homelab journey: https://bower.sh/homelab

Basically, containers and GPU is annoying to deal with, GPU pass through to a VM is even more annoying. Most modern hobbyist GPUs also do not support splitting your GPU. At the end of the day, it’s a bunch of tinkering which is valuable if that’s your goal. I learned what I wanted, now I’m back to arch running everything with systemd and quadlet

Why would I want add overheard and complexity to my system when I don't need to? I can totally see legitimate use cases for docker, and work for purposes I use VMs constantly. I just don't see a benefit to doing so at home.

Have done it both ways. Will never go back to bare metal. Dependency hell forced multiple clean installs down to bootloader.

The only constant is change.

Curious to know what the experiences are for those who are sticking to bare metal. Would like to better understand what keeps such admins from migrating to containers, Docker, Podman, Virtual Machines, etc. What keeps you on bare metal in 2025?

If it aint broke, don't fix it 🤷

For me the learning curve of learning containers does not match the value proposition of what benefits they're supposed to provide.

Ok I’m arguing for containers/VMs and granted I do this for a living… I’m a systems architect so I build VMs and containers pretty much all the time time at work… but having just one sorta beefy box at home that I can run lots of different things is the way to go. Plus I like to tinker with things so when I screw something up, I can get back to a known state so much easier.

Just having all these things sandboxed makes it SO much easier.

I'm using proxmox now with lots of lxc containers. Prior to that, I used bare metal.

VMs were never really an option for me because the overhead is too high for the low power machines I use -- my entire empire of dirt doesn't have any fans, it's all fanless PCs. More reliable, less noise, less energy, but less power to throw at things.

Stuff like docker I didn't like because it never really felt like I was in control of my own system. I was downloading a thing someone else made and it really wasn't intended for tinkering or anything. You aren't supposed to build from source in docker as far as I can tell.

The nice thing about proxmox's lxc implementation is I can hop in and change things or fix things as I desire. It's all very intuitive, and I can still separate things out and run them where I want to, and not have to worry about keeping 15 different services running on the same version of whatever common services are required.

pff, you call using an operating system bare metal? I run my apps as unikernels on a grid of Elbrus chips I bought off a dockworker in Kamchatka.

and even that's overkill. I prefer synthesizing my web apps into VHDL and running them directly on FPGAs.

until my ASIC shuttle arrives from Taipei, naturally, then I bond them directly onto Ethernet sockets.

/uj not really but that'd be sick as hell.

Warms me heart to see people in this thread thinking for themselves and not doing something just because other people are.

Im a hobbiest who just learned how to self host my own static website on a spare laptop over the summer. I went with what I knew and was comfortable with which is a fresh install of linux and installing from the apt package manager.

As im getting more serious im starting to take another look at docker. Unforunately my OS package manager only has old outdated versions of docker I may need to reinstall with like ubuntu/debian LTS server something with more cutting edge software in repo. I don't care much for building from scratch and navigating dependency roulette.

In my own experience, certain things should always be on their own dedicated machines.

My primary router/firewall is on bare metal for this very reason.

I do not want to worry about my home network being completely unusable by the rest of my family because I decided to tweak something on the server.

I could quite easily run OpnSense in a VM, and I do that, too. I run proxmox, and have OpnSense installed and configured to at least provide connectivity for most devices. (Long story short: I have several subnets in my home network, but my VM OpnSense setup does not, as I only had one extra interface on that equipment, so only devices on the primary network would work)

And tbh, that only exists because I did have a router die, and installed OpnSense into my proxmox server temporarily while awaiting new-to-me equipment.

I didn't see a point in removing it. So it's there, just not automatically started.

My servers and NAS were created long before Docker was a thing, and as I am running them on a rolling release distribution there never was a reason to change anything. It works perfectly fine the way it is, and it will most likely run perfectly fine the next 10+ years too.

Well I am planning, when I find the time to research a good successor, to replace my aging HPE ProLiant MicroServer Gen8 that I use as Homeserver/NAS. Maybe I will then setup everything clean and migrate the services to docker/podman/whatever is fancy then. But most likely I will only transfer all the disks and keep the old system running on newer hardware. Life is short...

It's so simple that it takes so much less time, one day I may move to Podman but I need to have the time to learn. I host Jellyfin

This reminds me of a question I saw a couple years ago. It was basically why would you stick with bare metal over running Proxmox with a single VM.

It kinda stuck with me and since then I've reimaged some of my bare metal servers with exactly that. It just makes backup and restore/snapshots so much easier. It's also really convenient to have a web interface to manage the computer

Probably doesn't work for everyone but it works for me

It's just another system to maintain, another link in the chain that can fail.

I run all my services on my personal gaming pc.

The fact that I bought all my machines used (and mostly on sale), and that not one of them is general purpose, id est, I bought each piece of hardware with a (more or less) concrete idea of what would be its use case. For example, my machine acting as a file server is way bigger and faster than my desktop, and I have a 20-year-old machine with very modest specs whose only purpose is being a dumb client for all the bigger servers. I develop programs in one machine and surf the internet and watch videos on the other. I have no use case for VMs besides the Logical Domains I setup in one of my SPARC hosts.

Well, that is how I started out. Docker was not around yet (or not mainstream enough, maybe). So it is basically a legacy thing.

My main machine is a Frankenstein monster by now, so I am gradually moving. But since the days when I started out, time has become a scarce resource, so the process is painfully slow.

I've not cracked the docker nut yet. I don't get how I backup my containers and their data. I would also need to transfer my Plex database into its container while switching from windows to Linux, I love Linux but haven't figured out these two things yet

I run my NAS and Home Assistant on bare metal.

• NAS: OMV on a Mac mini with a separate drive case
• Home Assistant: HAOS on a Lenovo M710q, since 1) it has a USB zigbee adapter and 2) HAOS on bare metal is more flexible

Both of those are much easier to manage on bare metal. Everything else runs virtualized on my Proxmox cluster, whether it's Docker stacks on a dedicated VM, an application that I want to run separately in an LXC, or something heavier in its own VM.
