# Petclinic Demo Jonathan Scaf 2

> A deployment of the Spring PetClinic application, scaffolded via Backstage and managed with ArgoCD in the `demo-apps` namespace.

## Overview

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 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.

## Repository

| Field | Value |
|---|---|
| Source Repo | [Petclinic Demo Jonathan Scaf 2](https://gitea.kyndemo.live/validate/petclinic-demo-jonathan-scaf-2) |
| Branch | `main` |
| ArgoCD App | `petclinic-demo-jonathan-scaf-2` |
| Namespace | `demo-apps` |

## Architecture

- The service is based on the Spring PetClinic application, cloned from the upstream repository at `https://github.com/spring-projects/spring-petclinic`.
- OpenTelemetry auto-instrumentation is applied via Kustomize overlays, enabling comprehensive observability.
- ArgoCD manages the deployment, continuously syncing changes from the `main` branch to the `demo-apps` namespace.
- The deployment flow includes CI workflows, Backstage catalog entity creation, and integration with monitoring and load-testing tools.

## Configuration

| Configuration | Description |
|---|---|
| `spring.profiles.active` | Specifies the active Spring profile (`mysql`, `postgres`, or default H2). |
| Database URLs | H2: `jdbc:h2:mem:<uuid>`; MySQL and PostgreSQL require external setup. |
| OpenTelemetry Endpoint | `http://otel-collector.monitoring.svc.cluster.local:4318` |

## Operations

### 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 monitors the repository and automatically syncs changes to the `demo-apps` namespace.

### Rollback

1. Open the [ArgoCD UI](https://argocd.kyndemo.live/applications/petclinic-demo-jonathan-scaf-2).
2. Click **History and Rollback**.
3. Select the desired revision and click **Rollback**.

Alternatively, revert the commit in Git and push — ArgoCD will auto-sync the rollback.

## Observability

This service has OpenTelemetry auto-instrumentation enabled. Traces, metrics, and logs are exported to the OTel Collector and visualized in Grafana.

- **Grafana Dashboard**: [OpenTelemetry Application Observability](https://grafana.kyndemo.live/d/otel-app-observability-v2/opentelemetry-application-observability?orgId=1&var-app=petclinic-demo-jonathan-scaf-2)
- Filter by `app=petclinic-demo-jonathan-scaf-2` to see service-specific data.
- Alerts are configured via Grafana and can be monitored in Backstage.
