Help me choose my setup, please! (self.selfhosted)

I have a server configuration to what i though would be best, and that is running a Debian, then installing a service i most frequently use, and use containers for other services. But, now i think that’s not a good solution and i’m looking for advice.

I thought of something like this:

Proxmox install Spin up a VM for this service that is currently running on Debian (can’t be in a container) Spin up a second VM, install Debian and Docker and install all other services as containers.

That would enable me to: a) backup the 1st VM to be able to deploy it if needed (backups) b) backup containers in the second VM so i can have them ready to be restored if needed

However, i’m not sure about setting it up like this. I’m worried if Jellyfin will work good as a container on a VM. Also, i’m worried about setting up nginx in a container on a VM, like, will it work as if installed on bare metal.

Other services i’m planning to run in containers on that 2nd VM are BookStack, Joplin, Mosquitto broker, Grafana, MariaDB, Influx DB, Studio Code, JellyFin, NectCloud etc.

The machine is a i3 1315U, 16GB RAM, 500GB SSD.

For the first VM i would allocate 2 cores and 4GB of RAM (that’s enough for what it does) and for the second VM (with all the containers) i would allocate the rest of the CPU and RAM.

Any advice is very welcome! Is proxmox still the best choice? Are there any other (better) choices? Is something obviously wrong with this setup?

In your scenario I don't think I'd use Proxmox as you're going to run into issues with lack of RAM. I think you're going to have issues running out of memory either way though. Running the whole machine as a Docker node would probably be more memory-efficient than having the overhead of running separate VMs under Proxmox.

NGINX should run fine as a container. There's even an official build available on Docker Hub.

Am i getting this right:

Install Debian, setup a VM for the service (2gb, 2 cores) Install Docker on the same Debian OS, without virtualization, deploy containers?

I totally missed that you have an uncontainerized service. Can you run the service directly on the hardware host (safely)? If so, here's how I would probably run it considering your memory constraints:

Install Debian
Set up the uncontainerized service directly on the host.
Install Docker directly on the host as well.
Spin up the containers for everything else.

Not the cleanest/most separated answer but it would reduce the memory load of additional layers of host/VM/containers. If this isn't storing any sensitive data or being directly exposed to the internet that should be fine.

If you are dealing with sensitive data or exposing to the internet, I would consider your original plan of Proxmox VMs to separate everything but see if you can add additional RAM to help. Also consider installing something like fail2ban on every host and VM.
