Documentation

oci-instance-pool-autoscaling — Instance Pool with Autoscaling

A self-healing OCI instance pool built from an immutable instance configuration, with optional metric-based (CPU/memory threshold) and schedule-based (cron) autoscaling, and automatic load-balancer backend registration. Works with Terraform and OpenTofu (>= 1.6), OCI provider >= 8.0, < 9.0.

Status: static-validated, live-test pending. Ships under live-test quarantine — validated with tofu fmt, tofu validate, and tflint. Real apply → scale → destroy against an OCI tenancy is pending a cloud sandbox. Testable cheaply with micro shapes, so this is a strong early candidate once the live lane exists.

Secure / sane defaults

  • No public IP by default. Pool instances sit in a private subnet behind a load balancer; assign_public_ip = false. Scope ingress to the LB with nsg_ids (deny-by-default).
  • Legacy IMDS (v1) disabled on every launched instance (OCI's IMDSv2 enforcement).
  • Encryption at rest always on — bring your own Vault key via boot_volume_kms_key_id; in-transit encryption on by default.
  • Deterministic template. image_id is required — the pool launches from a pinned image so scale-outs are reproducible (no platform-image drift).
  • Bounded scaling. capacity (min/initial/max) caps how far autoscaling can grow or shrink the pool; cool-down floors at 300s.

Requirements

  • Terraform or OpenTofu >= 1.6
  • oracle/oci >= 8.0, < 9.0
