Building CentOS images for Proxmox using Packer

A while back I took the time to learn a bit of OpenStack’s Disk Image Builder. Recently I decided to give Packer a try to build templates for Proxmox and I decided to release the results as a Github repo. You can find the repo at The project allows you to build a mostly empty CentOS 7 or CentOS 8 template for Proxmox. You can further customize the image by expanding the provisioner section of the packer.json files.
