A project which builds a cloud-init enabled Ubuntu VM template on Proxmox. Improvements can be made, but it works OOTB as is, just make sure, that VM IDs 8999 and 9000 are not taken yet.
Nightly job first fetches the latest cloud-init enabled Ubuntu VM image, then prepares a Proxmox VM to template, packer creates a template from that prepared VM and configures the template with cloud-init defaults (SSH user and public key association). If the systemd service fails for any reason, it's configured to trigger the notify-email@%i.service. It also sends a notification with proxmox-mail-forward on successful build.
Installation is intended to be done on the Proxmox host itself.
