Kptfile is missing the emails field that is present in all other package examples (e.g., package-examples/nginx/Kptfile and package-examples/guestbook/Kptfile). This field should be added to the info section to follow the repository convention.

The example package is placed at the repository root level (ecommerce-example/) rather than in the package-examples/ directory where all other example packages are located. This breaks the established codebase convention. Consider moving this to package-examples/ecommerce to maintain consistency with the existing package organization (e.g., package-examples/nginx, package-examples/guestbook, etc.).

The Kptfile is missing the pipeline section with validators, which is a standard part of all other example packages in the repository (see package-examples/nginx/Kptfile and package-examples/guestbook/Kptfile). Adding a kubeconform validator would be consistent with existing examples and help users learn about kpt's validation capabilities.

# E-commerce Example (kpt)

This is a simple e-commerce application example packaged using **kpt**.

---

## 📌 Overview

This project demonstrates how Kubernetes applications can be managed and customized using the **kpt toolchain**.

Instead of modifying code, users can change configuration using YAML files.

---

## 🚀 Features

- Simple Kubernetes Deployment using **nginx** (version pinned for reproducibility)
- Service to expose the application internally
- Easy-to-understand structure for beginners
- Ready to extend with custom configuration

---

## 📂 Structure

- `deployment.yaml` → Defines the application Deployment
- `service.yaml` → Exposes the application via a Service
- `Kptfile` → Defines the kpt package metadata

---

## ⚙️ How to Use

### 1. Deploy the application

**Option A: Using kubectl only**
```bash
kubectl apply -f deployment.yaml -f service.yaml

The README.md file appears to be incomplete. The diff shows the file ends at line 38 with an unclosed bash code block, but line 39 exists (total of 39 lines). The documentation cuts off mid-sentence and does not include the complete "How to Use" section. Please complete the README with instructions for deploying with kpt.
