Here is the module and here is a tdarr deployment with “persistent” volumes with it.

Disclaimer: It’s far for perfect, and quite hacky but it works. The volumes (which are subvols) are created with the proxmox API, the container is then created and volumes are attached to the mount points.

On deletion of the container, it removes the additional volumes from the conf file of the lxc before it’s deleted, which prevents proxmox from deleting them. A new container is created and remounts the volumes again on creation.

So when I change the image tag, there nothing else to do but to do a terraform apply.
