Update PostgreSQL image and Umami revision.

Change Summary

This update involves modifications to the Terraform configuration files for the database and monitoring modules. Specifically, changes have been made to the main.tf files within the IaC/modules/database and IaC/modules/monitoring directories. The database module now specifies a new image repository, while the monitoring module has been updated to use a newer chart version.

Technical Details

• Database Module (IaC/modules/database/main.tf):
  • Added a new parameter to the argocd_application resource for the PostgreSQL database.
  • The new parameter specifies the image.repository as bitnamilegacy/postgresql.
  • This change ensures that the PostgreSQL deployment uses a specific image repository, enhancing control over the image version used.
• Monitoring Module (IaC/modules/monitoring/main.tf):
  • Updated the target_revision for the Umami chart from 5.0.8 to 6.0.1.
  • This revision update likely includes new features, bug fixes, or security patches provided by the Umami chart maintainers.

Key Learnings & Insights

• Version Control for Images: Specifying the image.repository explicitly helps in maintaining consistency across environments and avoids unexpected behavior due to automatic image updates.
• Keeping Charts Updated: Regularly updating Helm charts ensures that the deployed applications benefit from the latest improvements and security fixes.
• Configuration Management: Using Terraform for infrastructure as code (IaC) allows for version-controlled, reproducible infrastructure deployments.

Impact Assessment

• Performance: The change in the image repository might lead to performance improvements or changes depending on the new image’s optimizations.
• Security: Updating the Umami chart to a newer version enhances security by incorporating the latest patches.
• Maintainability: These changes improve maintainability by ensuring that the infrastructure aligns with the latest standards and best practices.
• Breaking Changes: There are no immediate breaking changes, but teams should verify that the new image and chart version are compatible with existing configurations.

Developer Notes

• Gotchas: Ensure that the new image repository bitnamilegacy/postgresql is accessible and trusted within your deployment environment.
• Edge Cases: Verify that the Umami chart version 6.0.1 does not introduce breaking changes or deprecated features used in the current setup.
• Future Improvements: Consider automating the process of updating Helm charts and Docker images to streamline future updates and reduce manual intervention.
