Add Terraform for Hetzner Cloud CX53 migration#1
Merged
Conversation
Provision a CX53 VPS (16 vCPU, 32GB RAM, 320GB NVMe) to replace the current AX42-U dedicated server, reducing monthly cost from ~€68 to ~€23. - Terraform: hcloud server + firewall + Cloudflare DNS records - CI: plan on PR, apply on merge (S3/Wasabi state backend) - MySQL config tuned for 32GB RAM (20GB buffer pool, lower I/O threads) - Setup script adds 4GB swap file for VPS Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
