I recently had to rebuild a proxmox node after a crash (and lack of backups :() so I took the effort to do things like make images with Packer, deploy with Terraform, configure with ansible etc. It was good learning, but honestly, if I have to do it again things will probably be pretty out of date and I’d be better off doing it manually. It’s a great approach if you plan to deploy thing regularly though (more lab rather than over engineered, for home, production).
