To generate jar files run the following command in root path:

Wait a minute, when you see all containers running yo can launch the Spring Boot microservices:

### Microservice for command

Once all microservice started you can test this serive using the command endpoint and service endpoint. I show you one example for POST and GET http rest requests with curl command:

```
curl --location --request POST 'localhost:8081/phone' \
--header 'Content-Type: application/json' \
--data-raw '{
    "name": "iphone11",
    "model": "11",
    "color": "red",
    "price": 800.99

```

```
curl --location --request GET 'localhost:8082/phone/iphone08'
```
