You can run Virtual Machines and containers in TrueNAS Scale directly. The “Apps” in TrueNAS run in K3s (a lightweight Kubernetes) and you can run plain Docker containers as well if you need to.

TrueCharts provides additional apps and services on top of the official TrueNAS supported selection.

I have used Proxmox a lot before TrueNAS. At work and in my homelab. It’s great, but the lack of Docker/containerd support made me switch eventually. It is possible to run Docker on the same host as Proxmox, but in the end everything I had was running in Docker. This made most of what Proxmox offers redundant.

TrueNAS has been a better fit for me at least. The web interface is nice and container based services are easier to maintain through it. I only miss the ability to use BTRFS instead of ZFS. I’ve had some annoying issues with TrueCharts breaking applications on upgrades, but I can live with the occasional troubleshooting session.

Could OBS can be setup like that?

What do you mean by this? Like what exactly?

Another workaround would be to use Bluetooth headphones or speaker.
