## Overview
|
||||
|
||||
The **Petclinic Demo Application** is a deployment of the Spring PetClinic sample application, tailored for demonstration purposes. It showcases a modern Java-based microservice architecture, leveraging Spring Boot for rapid development and deployment. The application is deployed via ArgoCD into the `demo-apps` namespace and includes integrations for observability, load testing, and chaos engineering.
|
||||
|
||||
This service plays a critical role in demonstrating best practices for application lifecycle management, including CI/CD workflows, OpenTelemetry instrumentation, and Kubernetes-based deployments. It serves as a reference implementation for teams adopting similar technologies and workflows.

|
||||
## Architecture
|
||||
|
||||
The Petclinic Demo Application is built on the Spring Boot framework and deployed as a containerized service in Kubernetes. Key architectural components include:
|
||||
|
||||
- **Spring Boot Application**: The core service, providing RESTful APIs and a web interface.
|
||||
- **Database**: Configurable to use H2 (in-memory), MySQL, or PostgreSQL, depending on the active profile.
|
||||
- **OpenTelemetry Integration**: Auto-instrumentation for tracing, metrics, and logs, exported to an OTel Collector.
|
||||
- **ArgoCD**: Continuous deployment and synchronization from the `main` branch.
|
||||
- **K6 Load Testing**: Configured for performance testing.
|
||||
- **Chaos Mesh**: Enabled for chaos engineering experiments.
|
||||
|
||||
Data flows through the application from user interactions to backend services, with observability tools providing insights into performance and reliability.

## Operations
|
||||
|
||||
### Deployment
|
||||
|
||||
1. Clone the repository:
|
||||
```bash
|
||||
git clone https://gitea.kyndemo.live/validate/petclinic-demo-andrej4.git
|
||||
cd petclinic-demo-andrej4
|
||||
```
|
||||
2. Push changes to the `main` branch:
|
||||
```bash
|
||||
git add . && git commit -m "your change" && git push origin main
|
||||
```
|
||||
3. ArgoCD will automatically sync changes to the `demo-apps` namespace.
|
||||
|
||||
### Rollback
|
||||
|
||||
1. Open the [ArgoCD UI](https://argocd.kyndemo.live/applications/petclinic-demo-andrej4).
|
||||
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 is fully instrumented with OpenTelemetry. Observability data is visualized in Grafana.
|
||||
|
||||
- **Grafana Dashboard**: [View Dashboard](https://grafana.kyndemo.live/d/otel-app-observability-v2/opentelemetry-application-observability?orgId=1&var-app=petclinic-demo-andrej4)
|
||||
- **Alerting**: Configured via Grafana with label selector `app.kubernetes.io/instance=petclinic-demo-andrej4`.
|
||||
|
||||
_Not configured — see platform observability docs for additional details._

## Overview
|
||||
|
||||
`sonar-test-nest4` is a stateless microservice built using the `typescript-nestjs` runtime. It was scaffolded from the **Create Microservice** golden-path template on the Kyndryl Platform. The service provides a REST API for managing items, including CRUD operations, and exposes observability endpoints for health checks and Prometheus metrics.

`sonar-test-nest4` is a stateless microservice built using the `typescript-nestjs` runtime. It was scaffolded from the **Create Microservice** golden-path template on the Kyndryl Platform. The service provides a REST API for managing items, including endpoints for CRUD operations. It is designed to be lightweight, scalable, and observable, with integrated OpenTelemetry instrumentation and Prometheus metrics.
|
||||
|
||||
This service plays a key role in the broader system by offering a scalable and observable backend for item management. It is deployed using Humanitec's API-driven deployment model, leveraging Azure Kubernetes Service (AKS) and Azure Container Registry (ACR). The CI/CD pipeline automates builds, tests, and deployments across development, staging, and production environments.
|
||||
This service plays a critical role in the demo-apps domain, serving as a testbed for platform capabilities such as CI/CD pipelines, observability, and load testing. It is managed via Humanitec and deployed to Azure Kubernetes Service (AKS) using Score-based configurations.

### Deployment Steps
|
||||
### Deployment Flow
|
||||
|
||||
1. Push changes to the `dev` branch for automatic deployment to the dev environment.
|
||||
2. Open a PR to promote changes from `dev` to `staging`. Ensure CI tests pass and obtain one approval.
|
||||
3. Open a PR to promote changes from `staging` to `prod`. Ensure CI tests pass and obtain one approval.
|
||||
4. Merge changes from `prod` to `main` for system-of-record updates.
|
||||
1. Push changes to the `dev` branch to trigger automatic builds and deployments to the dev environment.
|
||||
2. Promote changes to `staging` or `prod` via PRs, requiring CI checks and one approval.
|
||||
3. Use Backstage's CI/CD tab to monitor and trigger promotions between environments.
|
||||
|
||||
### Observability Endpoints
|
||||
### Runbook Notes
|
||||
|
||||
- `/health`: Returns `{"status":"UP"}` for health checks.
|
||||
