## Overview ## Overview
Petclinic Demo Jonathan Scaf 2 is a deployment of the Spring PetClinic application, a sample Spring Boot project designed to showcase best practices in Java application development. This service was scaffolded using the Backstage Application Migration Factory template and integrates OpenTelemetry for observability, K6 for load testing, and Chaos Mesh for chaos engineering. Petclinic Demo Jonathan Scaf 2 is a deployment of the Spring PetClinic application, a sample project showcasing Spring Boot capabilities. This service was scaffolded using the Backstage Application Migration Factory template, enabling automated CI/CD workflows and observability instrumentation. The application is deployed into the `demo-apps` namespace and continuously managed by ArgoCD.
The application provides a web interface for managing veterinary clinics, including features for scheduling appointments, managing pet records, and tracking clinic staff. It is deployed via ArgoCD, which continuously syncs the application from the `main` branch of its source repository into the `demo-apps` namespace. The Spring PetClinic application provides a simple interface for managing veterinary clinic operations, including customer, pet, and visit records. It is built using Spring Boot and supports multiple database configurations, including H2, MySQL, and PostgreSQL. This deployment integrates OpenTelemetry for observability and supports load testing with k6 and chaos engineering with Chaos Mesh.
This deployment is instrumented for monitoring and observability, with metrics and traces visualized in Grafana. It also supports rollback and automated sync workflows through ArgoCD.

# Petclinic Service # Petclinic
> A Spring Bootbased application for managing veterinary clinic operations, including scheduling, customer management, and pet records. > A Spring Bootbased application for managing veterinary clinics, including appointments, customers, and pets.
## Overview ## Overview
The Petclinic service is a Java-based application built using Spring Boot. It provides a comprehensive solution for managing veterinary clinic operations, including scheduling appointments, managing customer and pet records, and handling clinic workflows. Originally developed as a sample application by the Spring community, this service has been adapted and deployed as part of the `petclinic-demo-jonathan-scaf-2` system. The Petclinic service is a Java-based application built using Spring Boot. It provides functionality for managing veterinary clinic operations, including customer records, pet details, and appointment scheduling. The application is designed to be lightweight and modular, making it suitable for deployment in various environments.
The application supports multiple database configurations, including in-memory H2, MySQL, and PostgreSQL, and is designed to be easily deployable in containerized environments. It includes OpenTelemetry instrumentation for observability and integrates with ArgoCD for continuous deployment. The service plays a critical role in the broader veterinary platform, serving as the primary interface for clinic management. Originally sourced from the Spring Petclinic project, this service has been scaffolded and enhanced using the Backstage Application Migration Factory template. It includes OpenTelemetry instrumentation for observability and integrates with ArgoCD for continuous deployment. The service is deployed in the `demo-apps` namespace and is part of the broader `petclinic-demo-jonathan-scaf-2` system.

## Architecture ## Architecture
- The Petclinic service is scaffolded using the Application Migration Factory Backstage template. - The service is based on the Spring Boot framework, leveraging its modularity and ease of integration.
- Deployment flow: - OpenTelemetry auto-instrumentation is applied via a Kustomize overlay, enabling detailed observability for traces, metrics, and logs.
1. Source code cloned from the original Spring Petclinic repository. - Continuous deployment is managed by ArgoCD, which syncs changes from the `main` branch to the `demo-apps` namespace.
2. Backstage overlays applied for catalog entity creation and CI workflows. - The application supports multiple database configurations, including H2 (default), MySQL, and PostgreSQL, with profiles for each.
3. OpenTelemetry auto-instrumentation injected via Kustomize overlays.
4. ArgoCD Application created targeting the `demo-apps` namespace.
5. Continuous sync from the `main` branch via ArgoCD.
- Observability is enabled through OpenTelemetry, with metrics and traces visualized in Grafana.
