Terraform AWS Provider Version Update.

Change Summary

This update involves several key changes primarily focused on updating Terraform provider versions across multiple modules and configurations within the IaC (Infrastructure as Code) directory. Additionally, there is a minor change in the .devcontainer/devcontainer.json file and an update to the renovate.json configuration. The Terraform provider versions for aws, kubernetes, and argocd have been upgraded to ensure the project utilizes the latest features and security patches.

Technical Details

• .devcontainer/devcontainer.json:
  • Changed the value of TG_TF_FORWARD_STDOUT from true (boolean) to "true" (string). This might be to ensure consistency in environment variable types or to fix a bug where the boolean value was not being interpreted correctly.
• IaC/modules/*/init.tf:
  • Updated the aws provider version from ~> 5.0 to ~> 6.0 in multiple files:
    • cert-manager/init.tf
    • cloudflare-tunnel/init.tf
    • homarr/init.tf
    • tailscale/init.tf
• IaC/production/homelab/*/.terraform.lock.hcl:
  • Updated the aws provider version to 6.17.0 across various modules:
    • argocd
    • cert-manager
    • cloudflare-tunnel
    • database
    • descheduler
    • external-secrets
    • homarr
    • homeassistant
    • litellm
    • longhorn
    • monitoring
    • n8n
    • octobot
    • open-webui
    • tailscale
    • technitium
  • Updated the kubernetes provider version to 2.38.0 in multiple modules.
  • Updated the argocd provider version to 7.11.2 in several modules.
• renovate.json:
  • Added ":rebaseStalePrs" and "group:allNonMajor" to the extends array. This configures Renovate to rebase stale pull requests and group all non-major dependency updates together.

Key Learnings & Insights

• Version Consistency:
  • The changes demonstrate the importance of keeping Terraform provider versions consistent across all modules to avoid discrepancies and potential bugs.
• Security and Features:
  • Upgrading provider versions ensures that the infrastructure benefits from the latest security patches and features, which is critical for maintaining a secure and efficient environment.
• Configuration Management:
  • The update to renovate.json shows an effort to streamline dependency management by automatically handling non-major updates and keeping pull requests up-to-date.

Impact Assessment

• Performance:
  • The updated provider versions may include performance improvements, although specific gains would depend on the changes in each provider version.
• Security:
  • Upgrading to newer provider versions likely incorporates security fixes, reducing the attack surface of the infrastructure.
• Maintainability:
  • Consistent provider versions across modules simplify maintenance and reduce the likelihood of version-related bugs.
• Breaking Changes:
  • While the changes are primarily version upgrades, it’s important to test the infrastructure thoroughly to ensure that there are no breaking changes introduced by the new provider versions.

Developer Notes

• Testing:
  • Ensure to run comprehensive tests after applying these changes to verify that all Terraform configurations work as expected with the new provider versions.
• Documentation:
  • Update any relevant documentation to reflect the new provider versions and configurations.
• Future Improvements:
  • Consider setting up automated checks to regularly update Terraform provider versions to stay current with the latest releases.
