Packer Notes

---

Note: Cloud-Init was used to automatically apply the initial configuration to the VMs upon first boot. Packer was then used to build the final Proxmox image, with Proxmox serving as the build provider. The build_proxmox_iso.sh script present in the GOAD folder was used to create the ISO file with Cloud-init that was used by packer to create the final image.

Packer Commands

Initializing Packer:

packer init .

Validating Packer Config File:

packer validate -var-file=windows_server2019_proxmox_cloudinit.pkvars.hcl

Building Packer Image

packer build -var-file=windows_server2019_proxmox_cloudinit.pkvars.hcl

Default packer.pkr.hcl in GOAD folder (packer config file)
