Now, you can install nextcloud on the same docker VM that you install all other applications on as well. However, I personally have a dedicated VM for nextcloud since it is quite a heavy piece of software and if something goes wrong with nextcloud that affects the VM then it will not affect the other applications. Hence, what I first do is create again another Docker VM with the Docker VM Proxmox Helper Script. If you choose to host it on the same VM with Dockhand then you can also do this of course
