terraform-module-proxmox-cloudinit-template

Terraform module to template out cloudinit files to Proxmox hosts.

Limitations

This module can only template cloudinit config files out to a single host. To get around this I use an NFS mount on all hosts with snippets enabled. That way you can template out to a single host in your cluster irrespective on the host you want to land the instance on.
