Identify false-positive diffs in Terraform AzureRM plans caused by Set-type attribute ordering. 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 . - Analyzes terraform plan JSON output to distinguish spurious diffs (element reordering in Sets) from actual resource changes - Targets AzureRM resources with Set-type attributes: Application Gateway, Load Balancer, NSG, Firewall, Front Door, and others - Requires Python 3.8+ and uses only standard library; integrates into CI/CD pipelines with configurable output formats and exit codes - Helps reviewers focus on meaningful changes when terraform plan shows "all elements changed" despite minimal actual modifications - terraform plan shows many changes, but you only added/removed...
