s3 — S3 bucket

Module kind: primitive | Version: 1.0.0

A single S3 bucket for object storage. The simplest module — one resource, two inputs, two outputs. Versioning is enabled by default.

Resources

Resource	Type	Purpose
bucket	aws_s3_bucket	The S3 bucket itself

Inputs

Name	Type	Required	Default	Description
bucket_name	string	yes	—	Globally-unique S3 bucket name
region	string	yes	—	AWS region the bucket is created in

Outputs

Name	Type	Description
bucket_arn	arn	The S3 bucket ARN
bucket_name	string	The bucket name (echoes the input)

NFRs

Name	Type	Default	Description
versioning	boolean	true	Enable S3 versioning

Usage

{
  "id": "s3",
  "type": "aws:s3:bucket",
  "module": "s3@1.0.0",
  "inputs": {
    "bucket_name": "acdl-spike-bucket",
    "region": "us-east-1"
  }
}

A concrete instance is at instance.json (used by the platform pipeline as the regression baseline).

Compliance extension points

• Encryption at rest — add aws_s3_bucket_server_side_encryption_configuration with a customer-managed KMS key (SOC2 CC6.1, GDPR Art.32).
• Object Lock — add aws_s3_bucket_object_lock_configuration in compliance mode with 7-year retention for immutable evidence (SOX §802, DORA audit trail).
• Access logging — add aws_s3_bucket_logging to a target logging bucket (SOC2 CC7.2).
• Public access block — add aws_s3_bucket_public_access_block to prevent data exfiltration (SOC2 CC6.1, GDPR Art.32).
• Lifecycle policy — add aws_s3_bucket_lifecycle_configuration for retention enforcement (GDPR Art.5(2).

Examples

Validated example contracts are in examples/. The platform-test pipeline validates them against schemas/contract.schema.json.

Simple

A minimal deployment:

examples/simple.yaml

uses: acdl/pipelines/deploy.yaml@v1.6
module: s3
environment: dev
inputs:
  bucket_name: my-simple-bucket
  region: us-east-1

Complex

A production deployment with optional inputs:

examples/complex.yaml

uses: acdl/pipelines/deploy.yaml@v1.6
module: s3
environment: dev
inputs:
  bucket_name: my-production-bucket
  region: us-east-1

Note: the s3 primitive's compliance extensions (Object Lock, access logging, public access block, lifecycle policy) are documented in the Compliance extension points section above but not yet wired as inputs. The complex example uses the same inputs as the simple example; compliance extensions are roadmap.

Versioning

1.0.0 — interface MAJOR, behavior MINOR, lifecycle PATCH. MAJOR bumps require a new registry entry (immutable publication); old entries enter a 12-month deprecation window.
