Jon Chery 4bd07a4fae feat(P27): validated per-module examples (D-058) + schema glob fix
Add modules/<name>/examples/ directories with simple.yaml + complex.yaml
(+ mysql.yaml for RDS) for every primitive and module pattern. All 25
example contracts validate against schemas/contract.schema.json. Update
the contract schema to allow object/array input values (for env vars).
Fix the platform-test schema-validation glob to modules/*/*/examples/*.yaml
to match the nested l1/l2 path structure. Update the microservice sample
contract note (env objects now permitted by the schema).

vpc — VPC with subnets and routing

Module kind: primitive | Version: 1.0.0

A VPC with one subnet per availability zone and a route table with a default route through an internet gateway. The networking foundation that other modules (ALB, ECS service) reference for subnet ids.

Resources

Resource Type Purpose
vpc aws_vpc The VPC itself
subnet aws_subnet One subnet per availability zone
route_table aws_route_table Route table with default route 0.0.0.0/0
internet_gateway aws_internet_gateway IGW for public internet access
route_table_association aws_route_table_association Binds subnet to route table

Inputs

Name Type Required Default Description
cidr string yes VPC CIDR block, e.g. 10.0.0.0/16
azs string yes Comma-separated availability zones, e.g. us-east-1a,us-east-1b
name string yes Name tag for the VPC and child resources
region string yes AWS region the VPC is created in

Outputs

Name Type Description
vpc_id string The VPC id
subnet_ids string Comma-separated subnet ids

Usage

{
  "id": "vpc",
  "type": "aws:ec2:vpc",
  "module": "vpc@1.0.0",
  "inputs": {
    "cidr": "10.0.0.0/16",
    "azs": "us-east-1a,us-east-1b",
    "name": "acdl-microservice",
    "region": "us-east-1"
  }
}

The azs input is split on comma; one subnet is created per zone. The route table gets a default route 0.0.0.0/0 → internet gateway. Other modules reference subnet_ids for their network placement.

Compliance extension points

  • VPC Flow Logs — add aws_flow_log + CloudWatch Logs group / S3 destination (SOX ITGC, SOC2 CC7.2, HIPAA §164.312(b), DORA ICT risk logging).
  • Private subnets + NAT gateway — add private subnets with a NAT gateway so ECS tasks don't need public IPs (SOC2 CC6.6, PCI-DSS 1.3, HIPAA network isolation).
  • VPC endpoints — add S3, ECR, KMS, DynamoDB, CloudWatch interface/gateway endpoints to keep traffic off the public internet (SOC2 CC6.7, GDPR Art.32(1)(a), DORA ICT third-party risk).
  • Security groups — add aws_security_group as a first-class sub-resource (currently missing; needed for all regulated deployments) (SOC2 CC6.6, PCI-DSS 1.2).
  • Network ACLs — add aws_network_acl for subnet-level segmentation (PCI-DSS 1.3).

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.
