You should be able to do everything through the web interface.

You can make network shares by creating shared folders under Storage->Shared Folders then configure your Windows shares through Services->SMB/CIFS

Install the openmediavault-compose plugin to manage your docker containers.

I would also suggest installing the openmediavault-wireguard plugin for secure remote access to your services from outside your network.

This is great for a handful of devices but I deploy and administrate hundreds of devices at my school. As much as I would love to, there’s no way I could sell this without a really robust way of managing device policies & software deployment. I understand RHEL has something like that but that it isn’t quite up to the same standard as the Microsoft admin ecosystem just yet.
