Summary
The documentation page demonstrates a strong Windows/PowerShell bias. All CLI/scripted examples are exclusively provided in PowerShell, with no Bash, Azure CLI, or Linux-native command equivalents. The scripting sections assume the use of PowerShell cmdlets (Get-AzApplicationGateway, Add-AzApplicationGatewayBackendAddressPool, etc.), which are primarily Windows-centric. There are no Linux shell or cross-platform CLI examples, and the only automation path shown is via PowerShell. Additionally, the 'devx-track-azurepowershell' metadata and the ordering of examples (PowerShell before any mention of CLI) reinforce this bias.
Recommendations
  • Provide equivalent Azure CLI (az) examples for all PowerShell scripts, as Azure CLI is cross-platform and widely used on Linux and macOS.
  • Include Bash shell script examples where appropriate, especially for tasks like DNS configuration, certificate management, and HTTP requests (e.g., using curl).
  • Explicitly mention that all PowerShell scripts can be run on PowerShell Core on Linux/macOS, or clarify any Windows-only dependencies.
  • Add a 'Linux/macOS' tab alongside 'PowerShell' and 'Azure portal' for each procedural section, ensuring parity in automation and scripting guidance.
  • Avoid referencing only Windows tools or patterns (such as 'Invoke-WebRequest' without mentioning 'curl' or 'wget').
  • Update metadata and introductory text to reflect support for cross-platform management, not just PowerShell.
