Replace only root disk for LXC

[rwanito]

Hello,

I would to know if it's possible to update only the root disk for LXC container ?
The perfect way for me is to be able to use only tools like ansible proxmox or the proxmox api.

The first deployment can be done easily with mount points.
But, when I want to update my rootfs, it's very tricky to do it the most manually way possible.

I'm searching for a very flexible way to keep alive my data in mount point while replacing the root disk by a new root disk.

Thanks for your work !

Hi!
I update this.

I know, it's possible to manually keep the file /etc/pve/lxc..., recreate the CT and replace the new one by the old one.

But, is there a native way ?
Like docker, simply change the image and keep the volume.

Thanks !

Hi,
no, this is not possible without manual renaming. There will be a disk reassign feature at some point in the future (you could use that to re-assign the mountpoint from one container to the other), but other settings in the configuration would still need to be copied.

EDIT: update link to more recent version

Okay right.
I hope in next feature, it will be possible !

Thanks
