“What is stopping you from” <- this is a loaded question.

We’ve been hosting stuff long before docker existed. Docker isn’t necessary. It is helpful sometimes, and even useful in some cases, but it is not a requirement.

I had no problems with dependencies, config, etc because I am familiar with just running stuff on servers across multiple OSs. I am used to the workflow. I am also used to docker and k8s, mind you - I’ve even worked at a company that made k8s controllers + operators, etc. I believe in the right tool for the right job, where “right” varies on a case-by-case basis.

tl;dr docker is not an absolute necessity and your phrasing makes it seem like it’s the only way of self‐hosting you are comfy with. People are and have been comfy with a ton of other things for a long time.

Pure bare metal is crazy to me. I run proxmox and mount my storage there, and from there it is shared to machines that need it. It would be convenient to do a pass through to TrueNAS, for some of the functions it provides but I don’t trust that my skills for that. I’d have kept TrueNAS on bare metal, but I need so little horsepower for my services that it would be a waste. I don’t think the trade offs of having TrueNAS run my virtualisation environment were really worth it.

My router is bare metal. It’s much simpler to handle the networking with a single physical device like that. Again, it would be convenient to set up opnsense in a VM for failover. but it introduces a bunch of complexity I don’t want or really need. The router typically goes down only for maintenance, not because it crashed or something. I don’t have redundant power or ISPs either.

To me, docker is an abstraction layer I don’t need. VMs are good enough, and proxmox does a good job with LXCs so far.

Why would I spin up a VM and virtual network within that vm and then a container when I can just spin up a VM?

I’ve not spent time learning Docker or k8s; it seems very much a tool designed for a scale that most companies don’t operate at let alone my home lab.

Containers run on “bare metal” in exactly the same way other processes on your system do. You can even see them in your process list FFS. They’re just running in different cgroup’s that limit access to resources.

Yes, I’ll die on this hill.

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.

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 🤷

I’ve been self-hosting since the '90s. I used to have an NT 3.51 server in my house. I had a dial in BBS that worked because of an extensive collection of .bat files that would echo AT commands to my COM ports to reset the modems between calls. I remember when we had to compile the slackware kernel from source to get peripherals to work.

But in this last year I took the time to seriously learn docker/podman, and now I’m never going back to running stuff directly on the host OS.

I love it because I can deploy instantly… Oftentimes in a single command line. Docker compose allows for quickly nuking and rebuilding, oftentimes saving your entire config to one or two files.

And if you need to slap in a traefik, or a postgres, or some other service into your group of containers, now it can be done in seconds completely abstracted from any kind of local dependencies. Even more useful, if you need to move them from one VPS to another, or upgrade/downgrade core hardware, it’s now a process that takes minutes. Absolutely beautiful.

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

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)!

Erm. I’d just say there’s no benefit in adding layers just for the sake of it.

It’s just different needs. Say I have a machine where I run a dedicated database on, I’d install it just like that because as said there’s no advantage in making it more complicated.

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.

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.

I use Raspberry Pi 4 with 16GB SD-card. I simply don’t have enough memory and CPU power for 15 separate database containers for every service which I want to use.
