curl doesn't work on my machine, most install scripts don't work, nano edits crash, and mounts are inconsistent.

If your system is that fucked, I would wipe it and start over. And don't run any scripts or extra setup guides, they're not necessary.

Personally I run all my containers in a Debian VM because I haven't bothered migrating them to anything proxmox native. But gpu accel should work fine if you follow the directions from jellyfin: https://jellyfin.org/docs/general/post-install/transcoding/hardware-acceleration/

Just make sure you follow the part about doing it in docker.

It may be better now but I’ve always had problems with Docker in LXC containers; I think this has to do with my storage backend (Ceph) and the fact that LXC is a pain to use with network mounts (NFS or SMB); I’ve had to use bind mounts and run privileged LXCs for anything I needed external storage for.

Proxmox is about managing VMs and LXCs. I’d just create a VM and do all your docker in there. Perhaps make a second VM so you can shuffle containers around while doing upgrades.

If you plan to have your whole setup be exclusively Docker and you have no need for VMs or LXCs, then Proxmox might be a bunch of overhead you don’t need.

I use the LXCs for simple stuff that does a bare-metal type install within them, and I use the VMs for critical services like OPNSense firewall/routers. I also have a Proxmox cluster across three machines so I can live-migrate VMs during upgrades and prevent almost any downtime. For that use case it’s rock solid. It’s a great product and it offers a lot.

If you just need a single machine and only Docker, it’s probably overkill.

This is the way I'd imagine. I used this for Plex and this should make iGPU a lot easier.

How should Jellyfin be set up, lxc or vm

Either way. I prefer lxc, personally, but to each their own. lxc I think is drastically easier, in part because you don't need to pass through the whole GPU....

Is there a way to enable iGPU to pass to an lxc or VM without editing a .conf in nano?

You don't need to pass the igpu, you just need to give the LXC access to render and video groups, but yes, editing the conf is easiest. I originally wrote out a bunch here, then remembered there is a great video.

My Synology NAS is mounted to the host, but making mount points to the lxc doesn’t actually connect data

Do they show up as resources? I add my mount points at the CLI personally, this is the best way imo:

pct set 100 -mp0 /mnt/pve/NAS/media,mp=/media

This is done from the host, not inside the LXC.

Does your host see the mounted NAS? After you added the mount point, did you fully stop the container and start it up again?

Edit: You can just install curl/wget/etc BTW, its just Debian in there.

apt install curl

Edit 2: I must have glossed over the mount part.

Dont add your network storage manually, do it through proxmox as storage, by going to Datacenter > Storage > Add, and enter the details there. This will make things a lot easier.

https://tteck.github.io/Proxmox/ this is a good place to start. Also highly recommend youtube videos lots of good stuff there.

I run jellyfin on an LXC, so first get jellyfin installed personally I would separate jellyfin and your other docker containers, I have a separate VM for my podman containers. I need jellyfin up 100% of the time so that's why its separate.

Work on the first problem, getting jellydin installed I wouldn't use docker, just follow the steps for installing it on Ubuntu directly.

Second, to get the unprivileged lxc to work with your nas share follow this forum post: https://forum.proxmox.com/threads/tutorial-unprivileged-lxcs-mount-cifs-shares.101795/

Thirdly, read through the jellyfin docs for hardware acceleration. Its always best practice to not just run scripts blindly on your machine.

Lastly take a break if you can't figure it out, when I'm stuck I always need to take a day and just think stuff over and I usually figure out why its not working by just doing that.

If you need any help let me know!

There is a helper script for jellyfin LXC. From memory I can't help much, but I suggest searching for that. I think the default specs for disk space and RAM were weak, But setup was easy enough. After the initial helper script, you will need to learn how to mount the NAS into the LXC as well.
