To validate Azure Bicep deployments before execution, compile Bicep syntax and run Azure what-if previews to surface syntax errors, permission gaps, and unintended resource changes early. This preflight process generates a structured Markdown report summarizing issues and next steps.

Yes, you can run a what-if analysis on standalone Bicep templates. The validation process detects whether your repository uses standalone Bicep or azd projects, applying appropriate preview validations across resource group, subscription, management group, and tenant deployment scenarios.

Bicep preflight validation is the process of checking infrastructure changes before running them to reduce deployment risk. You need it before deploying an app stack to review the infrastructure plan and confirm the deployment is safe to proceed without unintended resource modifications.

Yes, Azure deployment validation detects RBAC permission issues during the what-if analysis. When it identifies RBAC limitations, it retries with reduced validation and records actionable remediation steps within the generated preflight report to help you resolve access gaps.

A key limitation of Azure what-if previews is that RBAC permission gaps can restrict full validation results. When this happens, the process retries with reduced validation and logs the specific permission limitations and remediation steps needed to complete the preflight check.

To generate a preflight report for Azure infrastructure changes, run Bicep syntax checks and what-if previews on your templates. The process produces a structured Markdown report that summarizes the tools used, issues found, and actionable next steps for your deployment.
