Update Terraform AWS and Kubernetes versions.

Change Summary

This git diff primarily focuses on updating Terraform provider versions across multiple modules and components within the IaC directory. Additionally, there are minor changes to configuration files and the addition of new settings in renovate.json.

Technical Details

• Configuration Update:
  • File: .devcontainer/devcontainer.json
  • Change: Updated TG_TF_FORWARD_STDOUT from true to "true". This change ensures the value is consistently treated as a string.
• Terraform Provider Versions:
  • Multiple files within IaC/modules and IaC/production/homelab have been updated to use newer versions of the hashicorp/aws and hashicorp/kubernetes providers.
  • The version of hashicorp/aws was updated from ~> 5.0 to ~> 6.0.
  • The version of hashicorp/kubernetes was updated from 2.37.1 to 2.38.0.
  • The version of argoproj-labs/argocd was updated from 7.8.0 to 7.11.2.
• Terraform Lock Files:
  • Various .terraform.lock.hcl files were updated to reflect the new provider versions and their respective hashes.
• Renovate Configuration:
  • File: renovate.json
  • Change: Added :rebaseStalePrs and group:allNonMajor to the extends array. This configures Renovate to rebase stale pull requests and group all non-major dependency updates.

Key Learnings & Insights

• Consistency in Configuration:
  • The change in .devcontainer/devcontainer.json highlights the importance of consistent data types in configuration files to avoid potential runtime issues.
• Version Management:
  • Updating Terraform providers to newer versions ensures access to the latest features, bug fixes, and security patches. It also helps in maintaining compatibility with other dependencies and infrastructure components.
• Automated Dependency Management:
  • The updates to renovate.json demonstrate the use of tools like Renovate to automate dependency management, reducing manual effort and ensuring dependencies are kept up-to-date.

Impact Assessment

• Performance and Features:
  • The updated Terraform providers may include performance improvements and new features that can enhance the overall infrastructure management.
• Security:
  • Newer versions of providers often contain security patches, which help in maintaining a secure environment.
• Maintainability:
  • Keeping dependencies up-to-date simplifies maintenance and reduces technical debt. It also ensures that the infrastructure code is compatible with the latest versions of cloud services.

Developer Notes

• Testing:
  • Ensure to thoroughly test the infrastructure after applying these changes to verify that all resources are provisioned correctly and that there are no breaking changes.
• Documentation:
  • Update the documentation to reflect the new provider versions and any changes in behavior or features that may affect the deployment process.
• Future Improvements:
  • Consider setting up automated tests for Terraform configurations to catch any issues introduced by dependency updates.
  • Explore the possibility of using Terraform version constraints more effectively to balance between stability and receiving updates.
