SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Validates ARM template deployments before execution by performing what-if analysis, permission checks, and generating a structured preflight report that highlights resource changes (create/modify/delete).

Core Features & Use Cases

  • What-if analysis to preview changes without deploying.
  • RBAC and permission validation to ensure deployment viability.
  • Structured preflight report detailing resource changes and gating decisions.
  • Supports subscription-level deployments and template-driven workflows.

Quick Start

Invoke the command /azure-deployment-preflight --deployment-id <deployment-id> to run a full preflight.

FAQPage Schema
How do I validate ARM template deployments before running them in Azure?▼

You can validate ARM template deployments by running a preflight analysis that executes what-if operations and permission checks to generate a structured report detailing resource changes before deployment.

Can I preview Azure subscription-level deployment changes without modifying resources?▼

Yes, running a preflight what-if analysis on subscription-level ARM template deployments allows you to preview resource changes like create, modify, and delete without actually deploying or modifying any resources.

Do I need Azure CLI access to check RBAC permissions for ARM template deployments?▼

Yes, Azure CLI access is required because the preflight validation directly invokes az deployment sub validate and az deployment sub what-if to check RBAC permissions and deployment viability.

What is the best way to generate a preflight report for Azure ARM templates?▼

The best way to generate a preflight report is to run a what-if analysis and permission check on your ARM templates, which outputs an availability, syntax, and change report saved under the .azure/deployments directory.

Does ARM template preflight validation work with template-driven workflows at the subscription level?▼

Yes, ARM template preflight validation supports subscription-level deployments and template-driven workflows by analyzing templates, checking permissions, and delivering structured what-if results before execution.

Why does my Azure ARM template deployment fail permission checks during what-if analysis?▼

ARM template deployments fail permission checks when the preflight analysis detects insufficient RBAC permissions required for deployment viability, which are flagged in the structured preflight report before execution.
