At the beginning, run the following services in order:

1. Discovery Service
2. Api-Gateway
3. Other Services

Every request will go through the API-Gateway where all other services are added. The Port to the Gateway is :8765

Second,

Swagger will help with having a very good visualisation of which endpoints are available in which service and what each endpoint does.

The swaggerdoc will run in different ports according to which service is required.

The url to swagger is: http://localhost:8084/swagger-ui/index.html#/

Available ports are:

• 8081 -> main app
• 8082 -> calculator app
• 8084 -> storage app

Third, using POSTMAN

Add a new product using the following request: http://localhost:8765/product/add
In POSTMAN try adding the following body to add a specific product, example:

`

{

"id": "1",
"name": "generator",
"price": 50,
"location": "Berlin",
"description": "light your whole house",
"color": "green",
"size": 100,
"weight": 15,
"type": "electrical",
"placeOfManufacture": "China"

}

`

Add a product detail to a given product id (ex: 1) using the following request: http://localhost:8765/product/1/details/

`

{ "id": 2, "productId": 1, "deliveryTime": 11, "productAmount": 100, "location": " Saturn" }

`

*** For the rest of endpoints check swagger...
