Verification

Plan-validated

Passed: module logic verified on a mocked plan - inputs, validation rules, conditional creation and outputs resolve (no real provider, no cloud).

Conformance

  • Static validation (fmt · validate · tflint)
  • No applicable security policies for this provider
  • Plan tests (mocked: validation rules · outputs)

Provenance

Functional

  • Live test pending (no cloud run yet)

Documentation

upcloud-server-stack

N identical UpCloud cloud servers on a dedicated SDN private network (with router), encrypted boot + data storage, SSH-key-only login, and a deny-by-default per-server firewall. One module call gives you a private east-west plane your servers share, with public exposure strictly opt-in. Works with Terraform and OpenTofu (>= 1.6), UpCloud provider >= 5.0, < 6.0. EU/Nordic-sovereign infrastructure, MIT-licensed provider.

Status: static-validated, live-test pending. Validated with tofu validate + tflint + checkov against the UpCloudLtd/upcloud provider. Not yet applied against a live UpCloud account (no cloud sandbox yet), so it ships under live-test quarantine.

Design & secure defaults

  • Private by default. Every server gets an SDN private NIC; the public IPv4 interface is opt-in (public_interface = false). Private-only servers are reached through a bastion or load balancer.
  • Deny-by-default firewall. The per-server firewall (firewall = true) carries explicit allow rules first, then a catch-all drop for all remaining inbound IPv4 and IPv6. SSH (22/tcp) opens only to the CIDRs in ssh_source_ranges — empty means SSH is closed.
  • Encryption at rest on (encrypt_storage = true) for the boot disk and any data disks.
  • SSH-key-only login. ssh_keys is required; create_password = false, so no password logins are provisioned.
  • Source IP filtering on every interface (anti-spoofing).
  • Dedicated router + SDN network per stack, with the DHCP default route left off so private-only servers do not silently gain an unexpected egress path.
  • plan xor cpu+mem is enforced by a precondition; a custom-sized server requires both cpu and mem.
