Is there a way to mount a folder from proxmox based filesystem in a container?

[Roger Simpson]

Hi all,

I would like to know if there is a way to mount a folder from the proxmox based filesystem in a container?

I currently do that through nullfs mount on a FreeBSD system where I have folder I exposed in the based system to within a jail - similar principle as a container in proxmox.

Has anybody done that? I cannot find a way to do that from the CT creation wizard GUI.

To clarify, if on a proxmox node, I have a ZFS pool named zdata and folder like /zdata/for_my_container, can I create a container and mount the content of for_my_container in that container?
I am sure I can have NFS or CIFS running on proxmox and get it to mount, I was hoping for something closer to my setup with FreeBSD jails and nullfs.

I see the documentation: https://pve.proxmox.com/wiki/Linux_Container#_bind_mount_points

Is there way to do that from the GUI?

Thanks in advance.

Hi,

mp0: /yourpool,mp=/mnt/data

This should work, I was trying the same 5 minutes ago.

Sorry where do you put that in the GUI?

You cannot, PVE is not a fileserver and therefore has no capability to do that. If you want to do that nonetheless, you have to go to the CLI.

This is possible since quite some time via GUI, see screenshot.

Otherwise, you can create a subvolume then add a mount point for it on the container's ressources page :

Is it correct ?

As far I understand him, he is talking about binding a previously created mountpoint/directory somewhere on the disk to the container. The screenshot is for creating a mount and adding that previously created mountpoint to the container. Conceptually two different things.

Your understanding is correct.
I can see the mount point from the GUI after created from the CLI but it does not seem to be feasible from the GUI.
I will look into the Proxmox API to see if I can create manage this settings.

Thank you all for all the answers and guidance - much appreciated

@Herkz already provided the answer. Just add that to your VM configuration on the CLI.

It's secure to mount the proxmox dump folder? I want to automatically save backup files from proxmox running Syncthink inside the container.

Thank you.
