Splitting Docker between SSD and HDD (lemmy.world)

I'm in the process of planning upgrades for my server, and I'm trying to figure out the "best" drive configuration for Docker. My general understanding would be that the containers should be running from an SSD, and any storage (images, videos, documents) should use a volume on an HDD.

Is it as simple as changing the data-root to point to the SSD, and keep my external volumes on the HDD as defined in my existing compose files? I've already moved data-root once b/c the OverlayFS was chewing up the limited space on the OS drive, so that process isn't daunting.

If there's a better way to configure Docker, I'm open to it, as long as it doesn't require rebuilding everything from scratch.

For reference, the server is running Debian Bookworm on an older i5 3400 with 32GB RAM.

Interesting. I'll dig a little more then. Most of my vm experience has been on desktop for various reasons, and it's almost always been a pain in the ass and not worth the effort.

I assume the kvm stuff can be running a minimal os, sort of like an alpine docker image?

It runs Proxmox as the base
