• Utilizes functional endpoints.
• Employs the PostgreSQL database.

• Java 17 or later - SDKMAN - Recommendation
• Gradle 7.6.1 or later - Gradle build tool Installation
• Docker 24.0.2 or later - How to install Docker
• Docker Compose 1.29.2 or later - Reference guide
• Minikube v1.31.2 or later - Get Started with Minikube
• Helm v3.10.1 or later - Installing Helm
• The project runs on port 8099 (http://localhost:8099).

Check versions:

• Java 17+

  java --version

• Docker

  docker -v

• Docker Compose

  docker-compose --version

This is an example of how to use the software and how to install it.

In the main project directory:

Docker build and start applications:

$ docker-compose up --build

Or use:

$ docker-compose up -d --build

To recreate the application in case of problems, use the command:

$ docker-compose down

$ kubectl apply -f delivery/k8s/postgres/.

$ kubectl apply -f delivery/k8s/application/.

$ minikube service delivery --url

http://192.168.49.2:32000

Inside the "k8s" folder, you will discover ".yaml" files utilized to deploy databases and applications within Kubernetes.

$ minikube addons enable metrics-server

To monitor the Horizontal Pod Autoscaler, employ the following command:

$ kubectl get hpa

[BETA] Because this hasn't been implemented following best practices.

$ helm install deliveryhelm deliveryhelm/

$ helm uninstall deliveryhelm deliveryhelm/

For the webhook checkout process, generate a QR code.

For testing full process with Mercado Pago webhook, use hookdeck.com with CLI to change the order status in the localhost application.

Apllication path /api/v1/mp-order/qr-code-checkout creates a checkout with Mercado Pago.

Example:

{
    "in_store_order_id": "75ca8fe9-3b1a-4053-8f3e-49a62e91f8e8",
    "qr_data": "00020101021243650016COM.MERCADOLIBRE02013063675ca8fe9-3b1a-4053-8f3e-49a62e91f8e85204000053039865802BR5908delivery6009SAO PAULO62070503***63042BFA"
