I‘m an old fart using FreeBSD and jails, in the jails mostly bare metal install. Home assistant runs in bhyve, one docker app (audiobookshelf) runs in bhyve as well (alpine linux and docker)
Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

A friend recommended me OpenSuse MicroOS, and it has been a great experience!
It's a atomic OS designed to be just enough to run containers and it does it perfectly. It updates and reboots itself automatically so I never have to worry about it.
IMO, perfect for a home environment, just wish the documentation was better.
Rocky Linux. Been using debian but I like firewalld a bit more than ufw, and I don't trust myself enough to let myself touch iptable.
Stage 1: Ubuntu server
Stage 2: Ubuntu server + docker
Stage 3: Ansible/OpenTofu/Kubernetes
Stage 4: Proxmox
Don't get me wrong, I use libvrt where it makes sense but why would anyone go to proxmox from a full iac setup?
I do 2 at home, and 3 at work, coming from 4 at both and haven't looked back.
Because it is much simpler to provision a VM
Maybe for the initial setup, but nothing is more repeatable than automation. The more manual steps you have to build your infra, the harder it is to recover/rebuild/update later
You automate the VM deployments.
if you're automating the creation and deployment of vms, and the downstream operating systems, and not doing some sort of HA/failover meme setup... proxmox makes things way more complicated than raw libvirt/qemu/kvm.
Debian on the servers, Diet-Pi on the SBC's, all containerized.
I run several different ones, Debian is the most, Ubuntu server runs a few and I have a couple of truenas scale instances simply because they have run truenas for years and work well. One is local network only, another is available but is used for storage and storage alone via s3/minio and sftp and duplicati
I have a nuc with Linux mint and host everything on docker containers. I expose any service I need through caddy.
Linux
Hypervisor: Proxmox (fuck Hyper-V: It's good but soo annoying. Fuck ESXi cuz Broadcom).
General purpose OS (for servers): Debian (and OMV)
Ubuntu Server. It just works.
archlinux + podman / libvirtd + nomad (libvirt and docker plugins) + ansible / terraform + vault / consul sometimes
UPD:
archlinux - base os. You never need change major version and that is great. I update core systems every weekend.
podman / libvirtd - 2 types of core abstractions. podman - docker containers management, libvirtd - VM management.
nomad - Hashicorp orcestrator. You can run exec, java application, container or virtual machine on one way with that. Can integrate with podman and libvirtd.
ansible - VM configuration playbooks + core system updates
terraform - engine for deploy nomad jobs (docker containers. VMs. execs or something else)
Vault - K/V storage. I save here secrets for containers and VMs
consul - service networking solution if you need realy hard network layer
As a result, I'm not really sure if it's a simple level or a complex one, but it's very flexible and convenient for me.
UPD2: As a result, I described the applications level, but in fact it is 1 very thick server on AMD Epic with archlinux. XD By the way, the lemmy node from which I write is just on it. =) And yes, it's still selfhosted.
