Documentation
hetzner-server-fleet
N-server fleet with placement group, firewall, primary IPs, and cloud-init —
Hetzner's price/perf with guardrails. One module call provisions identical
servers spread across physical hosts (a host failure costs you at most one
server), behind a deny-by-default cloud firewall, with managed primary IPv4
addresses that survive rebuilds and replacements. Works with Terraform and
OpenTofu (>= 1.6), hcloud provider >= 1.0, < 2.0.
Secure defaults:
- Deny-by-default firewall — no inbound port is open (incl. SSH) until you allowlist sources; only ICMP is allowed (toggleable)
- SSH-key-only access (
ssh_key_idsrequired; no root-password e-mails) - Spread placement group on by default (free anti-affinity)
- Stable, Terraform-managed primary IPv4s (
auto_delete = false) so addresses outlive any individual server - One-flag delete/rebuild protection across servers and IPs
Requirements
- Terraform or OpenTofu
>= 1.6 hetznercloud/hcloudprovider>= 1.0, < 2.0(managed primary IPs andpublic_netneed ≥ 1.36 — latest recommended)

Related modules
hetzner-snapshot
A Hetzner snapshot of a server, which is Hetzner's custom image, labelled by role and build so hcloud_image data sources can select the newest (unlabelled has to be accepted by name). The snapshot is the server at that moment, secrets and all: build the source clean and power it off first.
tencent-cvm-instance
A CVM instance in your subnet with login by key pair and no password, ordered security groups, no public address (one by name), the system disk encrypted with your KMS key (the service key by name), the Cloud Workload Protection and Cloud Monitor agents left on, a CAM role when you name one, and API termination refused. Pay-as-you-go by the hour.
aws-lightsail-instance
A Lightsail instance is created with 22 and 80 open to every address; its public address changes when it stops unless a static IP is attached, and every DNS record pointing at it is then wrong; and automatic snapshots are off. The port list replaced by your rules with SSH from anywhere accepted by name, a static IP attached, and the daily AutoSnapshot add-on on at the hour you choose.
scaleway-instance
A Scaleway instance on a Private Network with a required security group (the project default allows everything inbound), no public address unless a flexible IP is accepted by name, the project's SSH keys and no password, a Block Storage root volume deleted with the instance, cloud-init, and protection from deletion (off by name).
ibm-vsi-instance
A VPC virtual server in your subnet with the SSH keys you name and no password, security groups on the primary interface, no floating IP, the boot volume encrypted with a Key Protect key (IBM's key by name), secure boot on, and the metadata service on so a trusted profile can be the instance identity instead of a stored API key.
alicloud-ecs-instance
An ECS instance in your vSwitch with login by key pair and no password, no public address unless bandwidth above zero is accepted by name, the system disk encrypted with your KMS key (the service key by name), the metadata service on IMDSv2 only with a hop limit of one, the Security Center agent on, and deletion protection. Pay-as-you-go.
