Proxmox running TrueNAS and NextCloud or Nextcloud on TrueNAS via Docker? (self.selfhosted)

As the title states, how would you set it up? I've got an HP EliteDesk G5, what are the strengths and weaknesses of either:

ProxMox with one VM running TrueNAS and another VM running Nextcloud
TrueNAS on bare metal with Nextcloud running in docker
Some other setup

I'd like to be able to easily expand and backup the storage available to Nextcloud as needed and I'd also like the ability to add additional VMs/containers/services as needed

Honestly I haven't used Proxmox, but I assume they can share storage without having to set it up like a network drive? If not, SMB would work.

Proxmox uses scsi for disk images, which are single access only

Smb would be quite a lot of overhead, and it doesn't natively support linux filesystem permissions. You'll also run into issues with any older programs that rely on file locks to operate. nfs would be a much more appropriate choice. That said, apparmor in container images will usually prevent you from mounting remote nfs shares without jumping through hoops (that are in your way for a reason). You'll be limited to doing that with virtual machines only, no openvz/containerd.

Fun fact, it was literally the problems of sharing media storage between multiple workflows that got me to stop using virtual machines in proxmox and start building custom docker containers instead.

You can do the NFS mount in the VM and share it as a volume with the docker container.

Apparmor will complain and block the nfs mount unless you disable apparmor for the container. Then in a lot of cases the container won't be able to stop itself properly. At least that was my experience.
