Cómo usar

  1. 1Paste a focused Terraform file or module snippet.
  2. 2Review resource nodes, provider groups, module boundaries, and reference edges.
  3. 3Look for public resources, unmanaged dependencies, and names that do not match the intended environment.
  4. 4Use the exported diagram beside terraform plan output in pull request review.

FAQ

Can the diagram replace terraform plan?

No. The diagram explains structure. terraform plan remains the source for actual create, update, and destroy actions.

What Terraform patterns should I inspect visually?

Provider boundaries, module inputs and outputs, public networking resources, security groups, IAM policies, and references between compute and storage are good first checks.

Does it understand every Terraform expression?

No. It focuses on common resource and reference visualization. Complex dynamic blocks and provider-specific behavior still need human review.

Terraform Architecture Diagram visualizes resource blocks, providers, modules, and references so infrastructure changes are easier to review.

It is useful for AI-generated Terraform, pull request summaries, platform onboarding, and documenting cloud resources without manually drawing every dependency.

The diagram is a review aid, not a replacement for terraform plan, state inspection, or cloud security checks.

Demo: summarize Terraform resources for a pull request

A useful Terraform diagram shows what kind of infrastructure is being changed and how resources relate. It should make review faster before someone opens the full module.

  • Group resources by provider or module.
  • Call out public entry points and security boundaries.
  • Compare diagram structure with terraform plan before approval.
resource "aws_lb" "app" {}
resource "aws_security_group" "web" {}
resource "aws_ecs_service" "api" {
  load_balancer {
    target_group_arn = aws_lb_target_group.api.arn
  }
}
resource "aws_rds_cluster" "main" {}

Review pattern: turn Terraform changes into an architecture diff

Terraform files often hide topology changes inside resource blocks. A preview page should help reviewers see whether a pull request adds public ingress, new databases, queues, IAM paths, or cross-region dependencies.

  • Start with aws_lb, aws_api_gateway, google_compute_forwarding_rule, or azurerm_public_ip for ingress.
  • Group resources by module when the repository uses reusable modules.
  • Flag unmanaged references and data sources separately from resources that will be created.
resource "aws_sqs_queue" "orders" {
  name = "orders-prod"
}

resource "aws_lambda_function" "worker" {
  function_name = "order-worker"
}

Checklist de revisión para Terraform Architecture Diagram

Usa Terraform Architecture Diagram para inspeccionar visualmente contenido fuente antes de publicar documentación, notas de PR, incidentes o handoffs. Visualize Terraform resource blocks and references as a software architecture diagram.

Antes de exportar, revisa legibilidad, relaciones, datos sensibles y si la vista sigue teniendo sentido tras editar la entrada.

Límites y solución de problemas

Si la vista falla, reduce la entrada al ejemplo completo más pequeño, valida la sintaxis y agrega secciones gradualmente.

Trata la vista como superficie de revisión, no como fuente de verdad. Los resultados críticos requieren validación humana.

Entradas de ejemplo

  • AWS web: resource "aws_lb" "app" {} resource "aws_ecs_service" "api" { load_balancer { target_group_arn = aws_lb.app.arn } } resource "aws_rds_cluster" "main" {}
  • GCP queue: resource "google_cloud_run_service" "api" {} resource "google_pubsub_topic" "events" {} resource "google_bigquery_dataset" "warehouse" {}
  • Modules: resource "aws_vpc" "main" {} resource "aws_subnet" "private" { vpc_id = aws_vpc.main.id } resource "aws_db_instance" "postgres" {}
