Access Nextcloud Docker > Synology

[Gina_Lyrat]

Hello everyone, I was using a Synology NAS. I now have Nextcloud running in Docker following instructions from Mariushosting.

Now my question is, how can I access the data on the Synology via Nextcloud? I have tried something here > Do I have to enter the path in the stack or enter something under Portainer > Containers > Nextcloud > Volume mapping?

I would like to have access to the following example ‘/volume1/Public’. Can anyone help me?

I would like to have access to the following example ‘/volume1/Public’. Can anyone help me?

So you have to mount this path, i only see volume2 paths
And then you can in nc this include under external storage (local mount)

I have now mounted volume 1. None of the options I have currently set show anything in the folder > Storage is temporarily not available under External Storage

[amateurkicker]

Pls mount it not in the directory of nextcloud
Use /mnt or something else

/volume1/Public’

I’ve already tried that. But it doesn’t work. I read on the internet that different Linux systems are to blame (Synology + nextcloud) and that they only work via Teamfolder. Can nobody really help me here? This is not exactly a rare occurrence.
