My apologies; I have a computer running docker, who I hosts a plethora of services. I have an external drive connected to it (because i don’t have a NAS) and have it mounted to my underlying OS on that Docker server computer. And each container than needs it, mounts directories from that drive.

All of this is internal network only. And another server manages VPN connectivity to my home network. So I have remote access to everything I need with minimal ports forwarded.
