azure-deployment-preflight

To validate Bicep syntax and check permissions before an Azure deployment, you can run a preflight validation that uses Bicep CLI for syntax checks and Azure CLI for what-if analysis. This process catches errors and generates a preflight-report.md at the project root.

Azure deployment what-if analysis is a preflight validation mechanism that previews infrastructure changes before execution. You need it to catch unexpected resource changes, syntax errors, or insufficient RBAC permissions prior to running azd provision or az deployment commands.

Yes, what-if validation applies to both azd-based projects and standalone Bicep deployments. The preflight process guides infrastructure previews across azd provision and az deployment commands, consolidating the results into a single detailed report.

To perform an end-to-end preflight check for an azd-based Bicep project, execute a validation workflow that runs Bicep CLI syntax checks, Azure CLI what-if analyses, and permission validations. The process outputs a consolidated preflight-report.md file in your project root.

Azure Bicep deployments fail due to syntax errors, insufficient RBAC permissions, or unexpected changes. Running a preflight validation before execution identifies these specific issues by performing Bicep syntax checks and what-if analyses to prevent deployment failures.

Preflight what-if analyses rely on Bicep CLI for syntax checks and Azure CLI for deployment validation, meaning they require these tools to be installed. The process provides previews and guidance but does not execute the actual deployment or automatically fix the detected permission or syntax errors.
