terraform-azurerm-set-diff-analyzer

Terraform plan diffs for AzureRM resources often show changes for Set-type attributes due to element order rather than actual resource changes. This false-positive noise masks real additions or removals during reviews and CI/CD pipeline execution.

Run the analyze_plan.py script against your Terraform plan JSON file or via stdin. It separates order-only false-positive diffs from real additions, removals, and modifications in AzureRM Set-type attributes, generating a structured report.

Yes, the analyzer supports nested Set structures and primitive element sets. It offers optional case-insensitive comparisons and include/exclude filters for targeted AzureRM resources like Application Gateway, NSG, and Load Balancer.

Yes, the analyzer produces human-readable Markdown, JSON, or summary outputs from Terraform plan JSON. These structured formats are suitable for PR comments, dashboards, and CI/CD pipeline integrations to distinguish order-only diffs.

Use a set-diff analyzer that loads AzureRM Set attribute definitions and evaluates Terraform plan JSON. It distinguishes order-only changes from actual additions, removals, and modifications, preventing false-positives in CI/CD reviews.

The analyzer handles both nested Set structures and primitive sets, loading definitions from references/azurerm_set_attributes.json. It applies optional case-insensitive comparisons and filtering, but requires valid Terraform plan JSON input to function correctly.
