Update N8N module to v2.0.x.

Change Summary

This git diff reflects updates to pre-commit configurations, Terraform module adjustments for an n8n deployment, and a version update for the ArgoCD provider within a Terraform lock file. The primary focus is on enhancing configuration management and ensuring up-to-date dependencies for infrastructure as code (IaC) deployments.

Technical Details

• .pre-commit-config.yaml:
  • Updated the hook ID from terraform-fmt to tofu-fmt, aligning with the latest naming conventions or tool updates.
• IaC/modules/n8n/main.tf:
  • Modified the ArgoCD application configuration for n8n to use a more specific version (1.122.x) for the n8n image, enhancing version control and stability.
  • Changed the target revision of the n8n Helm chart from 1.0.10 to 2.0.x, reflecting an upgrade to leverage new features or bug fixes.
  • Adjusted the ingress configuration to specify a className of “traefik” and updated the path configuration to include pathType, improving routing specificity and compatibility with Kubernetes ingress controllers.
• IaC/production/homelab/n8n/.terraform.lock.hcl:
  • Updated the ArgoCD provider version from 7.12.3 to 7.12.4, ensuring the use of the latest provider version with potential bug fixes and improvements.

Key Learnings & Insights

• The transition from terraform-fmt to tofu-fmt suggests an adaptation to new tool standards or a shift in the project’s tooling strategy, emphasizing the importance of staying current with technology evolutions.
• Specifying a more precise version for container images and Helm chart revisions highlights a best practice in dependency management, reducing the risk of unexpected behavior due to broad version ranges.
• The ingress configuration updates demonstrate an awareness of the importance of adhering to Kubernetes ingress specifications, which can affect routing efficiency and security.

Impact Assessment

• These changes are expected to improve the stability and security of the n8n deployment by locking down versions more tightly and adopting the latest provider versions.
• The update to the ingress configuration, while seemingly minor, could have significant implications for how traffic is routed to the n8n service, potentially affecting performance and accessibility.

Developer Notes

• When working with these changes, ensure that the new versions of tools and providers are compatible with the existing infrastructure and that any breaking changes are accounted for.
• Pay attention to the ingress configuration updates, as they might require adjustments in networking setups or DNS configurations.
• Consider documenting the reasoning behind version choices (e.g., why 1.122.x for the n8n image) to aid future maintenance and upgrades.
