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?
Thanks for the input. Do you think i will be running out of RAM in that configuration, like other commenters noted?
The reason I’d like to have two separate VMs is easier backups/restores, that way i don’t have to care about the phisycal machine, if i want to move to something else i only have to restore the VM.
As for the backups, i have one local backup on a separate machine (NAS) that gets backed up to an external drive, then another dedicated backup NAS that backups the first NAS and is otherwise disconnected from the internet, local network and power (turns on only once a week to backup), then another backup that backups the backup NAS to an off-site NAS, that also has an external drive making daily backups. Is that ok?
You would have 12 GB ram shared over all the dockers. I think you will be fine. Unless everything will be used intensively continuously. But that’s my opinion. Just give it a shot, nothing to loose. Promox itself does not take so much. So if it it does not run in this setup you need different hardware anyhow.
I don’t like the solution of running docker next to proxmox, not in a vm, you want proxmox to respond even if the docker vm is busy/overloaded.
In terms of backup you should be good. I would skip that weekly local backup construction, not sure what that adds if the off site backup is working reliable. I’ld format that one and add proxmox to it and make proper use of it (like a second docker vm)
I’m using 2GB RAM at this moment, not accounting for Jellyfin and Nextcloud, and i don’t have info about their load because they’re on a windows server. That’s all running bare metal.
The offsite NAS is at my office, and is serving my office needs daily, i just added a backup of my home server to it.
Do you have any idea how much cores/ram should i leave to Proxmox?
None. Just use everything in the VM’s. Yes that’s over committing, but who cares if the lead normally is reasonable and you can watch the ’summary’ in pm to see how the system is doing. Stop worrying, grab the proxmox iso and have fun
Alright, yeah, i tend to overthink stuff to the point of not actually doing the thing i wanted. Thanks for the push!
