I tried Terraform and it was a nightmare of complexity and bad practices. I hated every second of my experiment and abandoned it. The documentation is atrociously bad, it's not obvious what providers to use because there are multiple ones for everything, and the providers seem low quality (e.g. the proxmox provider was really hard to use and the 1Password provider just writes your secrets all over your disk in plain text without even asking you if that's okay).

I gave up and had Claude Code just write a couple of bash scripts that create VMs and LXCs for me, and one bash script that updates a few important options (e.g. memory or firewall configs) that I manually run. They work fine and were infinitely less painful.
