terraform-azurerm-set-diff-analyzer

A skill to identify "false-positive diffs" in Terraform plans caused by AzureRM Provider's Set-type attributes and distinguish them from actual changes. Terraform's Set type compares by position rather than by key, so when adding or removing elements, all elements appear as "changed". This is a general Terraform issue, but it's particularly noticeable with AzureRM resources that heavily use Set-type attributes like Application Gateway, Load Balancer, and NSG. These "false-positive diffs" don't actually affect the resources, but they make reviewing terraform plan output difficult. If Python is unavailable, install via your package manager (e.g., apt install python3 , brew install python3 ) or from python.org . - terraform plan shows many changes, but you only added/removed a single element - Application Gateway, Load Balancer, NSG, etc. show "all elements changed" - You want to automatically filter false-positive diffs in CI/CD - Python 3.8+ - python: command not found : Use python3 instead, or install Python - ModuleNotFoundError : Script uses only standard library; ensure Python 3.8+ - scripts/README.md - All options, output formats, exit codes, CI/CD examples - references/azurerm_set_attributes.md - Supported resources and attributes
