SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps you distinguish between actual changes and "false-positive" diffs in Terraform plans caused by the ordering of elements within AzureRM Set-type attributes, making plan reviews much cleaner.

Core Features & Use Cases

  • Identify False Positives: Automatically filters out changes that are merely due to internal ordering of elements in Set-type attributes (e.g., in Application Gateway, Load Balancer, NSG).
  • Focus on Real Changes: Highlights only the actual additions, removals, or modifications within Set attributes.
  • Use Case: When terraform plan shows numerous changes for an azurerm_application_gateway's rewrite_rule_set, but you only added one rule, this Skill will tell you exactly which rule was added and ignore the spurious diffs.

Quick Start

Analyze the terraform plan JSON file named 'plan.json' using the default markdown output.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I filter false-positive Terraform plan diffs caused by AzureRM Set attribute ordering?▼

Filtering false-positive Terraform plan diffs involves analyzing plan JSON output to differentiate between order-only changes in AzureRM Set-type attributes and actual resource modifications, ensuring cleaner plan reviews.

Why does terraform plan show numerous changes for azurerm_application_gateway when I only added one rule?▼

Terraform plan shows numerous changes because AzureRM Set-type attributes often reflect internal element reordering as modifications. Analyzing the plan JSON filters these order-only diffs, highlighting only the actual rule added.

Can I integrate Terraform AzureRM plan diff analysis into CI/CD pipelines?▼

Yes, you can integrate Terraform AzureRM plan diff analysis into CI/CD pipelines using optional exit codes provided alongside the markdown, JSON, or summary output formats to flag genuine resource modifications.

Does the AzureRM Set diff analyzer support filtering by specific Terraform resource types?▼

Yes, the AzureRM Set diff analyzer supports filtering by specific Terraform resource types, allowing you to narrow plan JSON analysis to target resources like Application Gateways, Load Balancers, or NSGs for Set attribute changes.

What output formats are available when analyzing Terraform plan JSON for Set attribute changes?▼

Available output formats for analyzing Terraform plan JSON include markdown, JSON, and summary formats. These detail actual additions, removals, or modifications within Set attributes while excluding order-only false positives.

What are the limitations of using automated diff analysis for AzureRM Set attributes?▼

A limitation of automated diff analysis for AzureRM Set attributes is that it exclusively targets the AzureRM provider and requires Terraform plan JSON output. It specifically filters Set-type ordering changes and does not analyze other provider resources or non-Set attributes.
