Walking through the generated files

The files generated by JHipster are in the following structure. That is, each application will have its own folder and the files related to that service will be present inside it.

We will start with the gateway application. There will be three generated files, which will be the gateway-service, gateway-mysql, and gateway-deployment.yml files.

The following is the gateway-service.yml file:

apiVersion: v1
kind: Service
metadata: 
    name: gateway
    namespace: default
    labels:
        app: gateway
spec:
    selector:
        app: gateway
    type: LoadBalancer
ports:
 - name: web
   port: 8080

The first line defines the API version of Kubernetes, followed by the kind of template or object that this template carries. This template will have a service inside of it. 

Then, we will have the metadata information. Kubernetes uses this metadata...
