Migration from Upstream

Already using terraform-aws-modules? Change only the source URL:

module "s3_bucket" {
  source  = "terraform-aws-modules/s3-bucket/aws"
  version = "1.0"
}
module "s3_bucket" {
  source  = "soc2.compliance.tf/terraform-aws-modules/s3-bucket/aws"
  version = "1.0"
}

Same arguments. Same outputs. Compliance controls are enforced automatically at terraform plan. If a required value is missing, you get a clear validation error telling you what to set.

See the Migration Guide for step-by-step instructions.

Reversibility

No lock-in. Switch back by reverting the source URL to the upstream path:

module "s3_bucket" {
  source  = "terraform-aws-modules/s3-bucket/aws"
}

Run terraform init -upgrade. Terraform state is unchanged — same resource addresses, same provider, no compliance.tf-specific resources. Controls you already applied remain in AWS.
