## 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 provides a web-based interface for managing veterinary clinic operations, including scheduling appointments, managing pet records, and tracking visits. It is designed to demonstrate modern application deployment practices, including GitOps workflows, OpenTelemetry instrumentation, and integration with Kubernetes.
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 application is scaffolded using the Backstage Application Migration Factory template, which overlays CI/CD workflows and observability configurations. It is continuously deployed via ArgoCD, ensuring that changes pushed to the repository are automatically synced to the Kubernetes cluster.
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.

### Development Workflow - **Development Workflow**:
```bash
git clone https://gitea.kyndemo.live/validate/petclinic-demo-jonathan-scaf-2.git
cd petclinic-demo-jonathan-scaf-2
# make changes, then:
git add . && git commit -m "your change" && git push origin main
```
ArgoCD automatically syncs changes to the `demo-apps` namespace.
```bash - **Rollback**:
git clone https://gitea.kyndemo.live/validate/petclinic-demo-jonathan-scaf-2.git 1. Open the [ArgoCD UI](https://argocd.kyndemo.live/applications/petclinic-demo-jonathan-scaf-2).
cd petclinic-demo-jonathan-scaf-2 2. Click **History and Rollback**.
# make changes, then: 3. Select the desired revision and click **Rollback**.
git add . && git commit -m "your change" && git push origin main Alternatively, revert the commit in Git and push — ArgoCD will auto-sync the rollback.
```
ArgoCD monitors the repository and automatically syncs changes to the `demo-apps` namespace. <!-- TODO: FILL IN -->
