Use when provisioning or hardening a Hetzner Cloud VPS: picking the plan/location (CX/CPX/CAX/CCX), bringing it up reproducibly with hcloud + cloud-init, locking down SSH, and wiring the Cloud Firewall to hand off a Docker-ready host. NOT app deploys on Coolify (that is `coolify`), NOT Dockerfiles (that is `docker`), NOT another provider (that is `digitalocean`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hetzner — the cheap European box, made safe and reproducible Hetzner Cloud is chosen for one reason: price/performance. A 2 vCPU / 4 GB AMD box runs about €7.99/mo, the EU Intel line dips under €4, and EU locations include 20 TB of egress. The risk is that "cheap" becomes "unhardened and unmonitored" — a root-SSH box on a public IPv4 with password auth on. Your job is to make the cheap box **safe** and **reproducible**: every server comes up from a committed cloud-init file and a Cloud Firewall ruleset, never from click-ops in the console. A box you can't recreate from a file isn't a box, it's a pet. ## Decide before you create Pick the line, then the location. Prices are post-2026-04-01 (a price adjustment took effect that date); treat exact cents as "verify in the console." | Line | Chip | When to pick | Price band | EU-only? | |---|---|---|---|---| | **CX** | Intel (shared) | Cost-optimized, tiny EU workloads | ~€3.99/mo (2 vCPU/4 GB/40 GB) | Yes | | **CPX** | AMD (shared) | Default for apps; best general value | CPX22 ~€7.99, CPX32 ~€13.99, CPX42 ~€25.49 | No | | **CAX** | ARM64 (shared) | Cheapest per-core; ARM-clean workloads | Cheapest per-core | Yes | …

How to install
mdr add ericrisco/rsc-harness/hetzner@sha256:ccc7949ed0328e3aThe line at the top of this page pins the label git:20260729.ad893da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
