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, andtflint. 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 withnsg_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_idis 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

Related modules
oci-custom-image
A custom Compute image from exactly one source: an instance you built (its boot volume, secrets and all, so build it clean) or a QCOW2 or VMDK object in Object Storage with its operating system named, in the launch mode the workload needs (NATIVE for images built on OCI, PARAVIRTUALIZED for imports). OCI has no image family; the name carries the build.
oci-os-management-patching
An OS Management Hub scheduled job that installs every available update (security-only and the other partial operations by name) on the managed instance groups or compartments you name, weekly by an RRULE from a first run you set in the future, with a reboot window per instance and retries. Instances have to run the agent and be registered with a software source to be seen.
oci-compute-instance
Opinionated VM with E5/A1 flex shapes, cloud-init, attached block volumes, NSGs and in-transit encryption.
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).
