Summary of Changes

Hello @Manjeet-Singh2428, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request transforms a generic Terraform Azure module template into a specialized module for deploying Azure MySQL Flexible Servers. It introduces comprehensive configuration options, integrates private DNS, and enhances security features like Customer Managed Keys and Azure Entra authentication. The changes aim to provide a robust and configurable solution for MySQL deployments on Azure, complete with updated documentation and a detailed example.

Highlights

  • Module Refactoring: The module has been significantly refactored to provision an Azure Flexible Server for MySQL, moving from a generic template to a specialized module.
  • Private DNS Integration: The module now utilizes a dedicated private DNS module call for private DNS zone integration, replacing direct resource blocks.
  • Enhanced Configuration Options: Numerous new variables have been introduced, providing granular control over MySQL Flexible Server settings, including admin credentials, backup, networking, storage, database, high availability, diagnostics, Customer Managed Keys (CMK), and Azure Entra authentication.
  • Updated Documentation and Examples: The README and example configurations have been thoroughly updated to reflect the new module structure, inputs, outputs, and best practices for deploying a MySQL Flexible Server.

Code Review

This pull request introduces significant enhancements to the Azure MySQL module, including support for Customer-Managed Keys (CMK), private DNS integration, and Entra authentication. It also overhauls the module's variables, outputs, and documentation. While the new features are valuable, the review identified several issues that need attention. These include a critical cyclic dependency in the example code, incorrect resource naming conventions (e.g., pgsql instead of mysql), incomplete logic for restore scenarios, and improper tag handling. Additionally, there are multiple inconsistencies in the documentation and example files, such as outdated links and hardcoded secrets. Addressing these points will greatly improve the module's correctness, security, and usability.
