Terraform Outputs

After a successful Terraform Terraform
HashiCorp Terraform — provisions all platform infrastructure through five modules in `terraform/`. apply, read outputs from the demo repo root:

terraform -chdir=terraform output

Presentation layer

Output	Description
api_url	Base URL of API Gateway API Gateway Amazon API Gateway — REST API exposing `/catalog`, `/query`, and `/reprocess`. Browser CORS is locked to the Amplify hostname; CLI clients call the API Gateway URL directly. stage (null when presentation disabled)
amplify_app_id	Amplify Amplify AWS Amplify — hosts the Vite portal SPA. This walkthrough deploys via manual zip upload (no Git connection required). application ID
app_domain	Default Amplify app domain
app_url	Full HTTPS URL of the portal
cors_domain	Amplify branch hostname for API Gateway CORS

Ingest and storage

Output	Description
bucket_name	Data Lake Data Lake Private S3 bucket holding raw RINEX under `raw/rinexhourly/` and processed TEC output under `processed/tec/`. S3 S3 Amazon Simple Storage Service — data lake bucket for raw ingest and processed TEC output; S3 events trigger processing. bucket name (null when ingest disabled)

Processing

Output	Description
queue_url	Process_Queue Process_Queue SQS standard queue — receives S3 ObjectCreated notifications for new raw RINEX files; triggers processor Lambda ingest path. URL (S3 notifications)
reprocess_queue_url	Reprocess_Queue Reprocess_Queue SQS standard queue — buffers reprocessing job messages from the Reprocess API with lower concurrency than ingest. URL
jobs_table_name	DynamoDB DynamoDB Amazon DynamoDB — Jobs table tracks reprocessing job status by `job_id` (queued → processing → completed/failed). Jobs table name
processor_image_uri	Container image URI for processor Lambda processor Lambda Processor Lambda container — runs PyTECGg calibration per SQS message; adopted when a Batch on Fargate parallel-execution quota increase was rejected. Image from `ghcr.io/platformfuzz/tec-processor-image` mirrored to ECR.

Observability

Output	Description
cloudwatch_dashboard_name	CloudWatch CloudWatch Amazon CloudWatch — alarms, dashboard (`event-driven-platform`), and structured Lambda logs for observability. dashboard name ( event-driven-platform)
alarm_topic_arn	SNS SNS Amazon Simple Notification Service — publishes CloudWatch alarm notifications; subscribe an email endpoint after deploy. topic ARN for alarm notifications

Layer status

Output	Description
layers_enabled	Map of { ingest, processing, presentation } booleans

Common raw output commands

export API_URL="$(terraform -chdir=terraform output -raw api_url)"
export BUCKET="$(terraform -chdir=terraform output -raw bucket_name)"
export QUEUE_URL="$(terraform -chdir=terraform output -raw queue_url)"
export APP_URL="$(terraform -chdir=terraform output -raw app_url)"
export TOPIC_ARN="$(terraform -chdir=terraform output -raw alarm_topic_arn)"

URL usage

Use case	Output	Client
curl / scripts / Postman	api_url	CLI (no CORS)
Browser portal	app_url	Amplify SPA (requires CORS lockdown)
