authentications:

docker build --no-cache -t authentications:latest .

carts:

docker build --no-cache -t carts:latest .

customers:

docker build --no-cache -t customers:latest .

In the infra project folder, navigate to the monitoring folder. In this folder, you'll find the following files:

• docker-compose.dev.yml (development)
• docker-compose.prod.yml (production)

Execute the following command:

docker compose -f docker-compose.dev.yml up -d

Development for debugging:

Create the database for the products service, using pgAdmin 4:

• Access pgAdmin: http://localhost:5050
  • Login: admin@admin.com
  • Password: root
• Create a database named "products"
• Run the query for the products service: sql/01_init.up.sql within the "products" database to create the tables for this service. Restart the products-srv service in Docker.

---

Running with Kubernetes:

In the infra project folder, navigate to the k8s folder. In this folder, you'll find the following files:

• deploy.sh (deploy the application)

  • run the deploy.sh executable.

• destroy.sh (bring down the application)

  • run the destroy.sh executable.
