Update workflow, agent config, database, monitoring.

Change Summary

This update involves several key changes across different configuration files and modules. The primary focus is on enhancing the GitHub Actions workflow, configuring a new PR agent, updating database module settings, and modifying the monitoring module to use a newer version of a Helm chart.

Technical Details

• .github/workflows/default.yml:
  • Modified the uses directive to point to a different repository (stuhlmuller/workflows instead of rstuhlmuller/workflows). This change likely reflects a repository rename or a switch to a different fork.
• .pr_agent.toml:
  • Introduced a new configuration file to enable automated PR actions. Settings include enabling auto review, description, and improvement, as well as specifying PR events that trigger these actions.
• IaC/modules/database/main.tf:
  • Updated the PostgreSQL image repository from bitnamilegacy/postgresql to bitnami/postgresql.
  • Added new parameters for database authentication and metrics, including enabling service monitor for metrics.
• IaC/modules/monitoring/main.tf:
  • Updated the Prometheus configuration to use the kube-prometheus-stack chart from the Prometheus Community Helm charts repository, targeting version 27.13.0.

Key Learnings & Insights

• The switch in the GitHub Actions workflow repository highlights the importance of maintaining up-to-date and correct repository references in CI/CD pipelines.
• The introduction of .pr_agent.toml demonstrates the value of automating PR processes to enhance code review efficiency and quality.
• Updating the PostgreSQL image and adding metrics configurations shows a move towards more modern and observable infrastructure practices.
• The upgrade in the Prometheus Helm chart version indicates a commitment to using updated and community-supported monitoring solutions.

Impact Assessment

• These changes are expected to improve the CI/CD pipeline’s reliability by ensuring it points to the correct repository.
• Automated PR actions will likely speed up the review process and enforce code quality standards more consistently.
• The database and monitoring module updates aim to enhance system observability and maintainability, potentially leading to better performance and easier troubleshooting.

Developer Notes

• Ensure that the new PostgreSQL image is compatible with existing database configurations.
• Verify that the automated PR actions do not conflict with manual review processes.
• Monitor the impact of the new Prometheus chart version on existing monitoring setups and be prepared to adjust configurations as needed.
• Consider documenting the rationale behind these changes more extensively to aid future maintainers.
