Those who are hosting on bare metal: What is stopping you from using Containers or VM's? What are you self hosting? (lemmy.world)

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?

But, but, docker, kubernetes, hyper-scale convergence and other buzzwords from the 2010's! These fancy words can't just mean resource and namespace isolation!

In all seriousness, the isolation provided by containers is significant enough that administration of containers is different from running everything in the same OS. That's different in a good way though, I don't miss the bad old days of everything on a single server in the same space. Anyone else remember the joys of Windows Small Business Server? Let's run Active Directory, Exchange and MSSQL on the same box. No way that will lead to prob... oh shit, the RAM is on fire.

kubernetes

Kubernetes isn't just resource isolation, it encourages splitting services across hardware in a cluster. So you'll get more latency than VMs, but you get to scale the hardware much more easily.

Those terms do mean something, but they're a lot simpler than execs claim they are.

I love using it at work. Its a great tool to get everything up and running kinda like ansible. Paired with containerization it can make applications more "standard" and easy to spin back up.

That being said, for a home server, it feels like overkill. I dont need my resources spread out so far. I dont want to keep updating my kub and container setup with each new iteration. Its just not fun (to me).

The RAM. The RAM. The 🐏 is on fire. We don’t need no water let the mothefuxker burn.

Burn mothercucker, burn.

(Thanks phone for the spelling mistakes that I’m leaving).

Oh for sure - containers are fantastic. Even if you're just using them as glorified chroot jails they provide a ton of benefit.
