Update ArgoCD module versions.

Change Summary

This update involves upgrading several components within the infrastructure-as-code (IaC) modules. Specifically, the argocd Helm chart version and the argocd Terraform provider version have been updated across multiple modules.

Technical Details

• Argo CD Helm Chart:
  • File: IaC/modules/argocd/main.tf
  • Change: Updated the Argo CD Helm chart version from 9.0.5 to 9.1.7.
• Argo CD Terraform Provider:
  • Files: IaC/modules/*/init.tf (multiple modules including cert-manager, cloudflare-tunnel, database, etc.)
  • Change: Updated the Argo CD Terraform provider version from 7.11.2 to 7.12.3.

These changes ensure that all modules utilizing the Argo CD provider are synchronized with the latest version, potentially incorporating bug fixes, features, and security patches.

Key Learnings & Insights

• Version Synchronization: Keeping Terraform providers and Helm charts up-to-date is crucial for security and functionality. This change demonstrates the importance of regular version checks and updates.
• Modular Approach: The update was applied across multiple modules, showcasing the benefits of a modular IaC approach. It allows for consistent and widespread changes with minimal effort.
• Documentation: Clear documentation of such changes helps future developers understand the evolution of the codebase and the reasoning behind updates.

Impact Assessment

• Performance: The new versions may include performance improvements or optimizations.
• Security: Updated versions often contain security patches, reducing vulnerabilities.
• Maintainability: Synchronized versions across modules simplify maintenance and reduce the risk of version-related bugs.

Developer Notes

• Gotchas: Ensure that the new versions of the Argo CD Helm chart and Terraform provider are compatible with existing configurations and other dependencies.
