| 1. The `PolicyGateway` interface that implements all the RPC functions that are described in `policy.proto` file. |
| 2. The `MonitoringGateway` interface that communicates with a `Monitoring` service gRPC client to invoke key RPC functions described in `monitoring.proto` file. |
| 3. The `ContextGateway` interface that communicates with a `Context` service gRPC client to invoke key RPC functions described in `context.proto` file. |
| 4. The `ServiceGateway` interface that communicates with a `Service` service gRPC client to invoke key RPC functions described in `service.proto` file. |
| 5. The `DeviceGateway` interface that communicates with a `Device` service gRPC client to invoke key RPC functions described in `device.proto` file. |
| 6. The `PolicyService` interface that implements the Policy RPC methods by communicating with a `Monitoring` gRPC client, a `Context` gRPC client, a `Service` gRPC client, and a `Device` gRPC client through the `MonitoringService`, `ContextService`, `ServiceService`, and `DeviceService` interfaces respectively. |
| 7. The `MonitoringService` interface that implements the `SetKpiAlarm()` and `GetAlarmResponseStream()` methods by communicating with a `Monitoring` gRPC client through the use of the `MonitoringGateway` interface. |
| 8. The `ContextService` interface that implements the `GetService()`, `GetDevice()`, `GetPolicyRule`, `SetPolicyRule`, and `DeletePolicyRule` methods by communicating with a `Context` gRPC client through the use of the `ContextGateway` interface. |
| 9. The `ServiceService` interface that implements the `UpdateService()` method by communicating with a `Service` gRPC client through the use of the `ServiceGateway` interface. |
| 10. The `DeviceService` interface that implements the `ConfigureDevice()` method by communicating with a `Device` gRPC client through the use of the `DeviceGateway` interface. |
## Prerequisites
The TeraFlowSDN Policy Management service is currently tested against Ubuntu 20.04 and Java 11.
To quickly install Java 11 on a Debian-based Linux distro do:
```bash
sudo apt-get install openjdk-11-jdk -y
```
Feel free to try more recent Java versions.
## Compile
```bash
./mvnw compile
`
## Execute unit tests
```
`
## Run tests
```bash
./mvnw test
`
```
## Run service
`
```bash
./mvnw quarkus:dev
`
````
## Clean
```bash
./mvnw clean
```
## Deploying on a Kubernetes cluster
To create the K8s manifest file under `target/kubernetes/kubernetes.yml` to be used run
```bash
./mvnw clean package -DskipUTs -DskipITs
```
To deploy the application in a K8s cluster run
```bash
kubectl apply -f "manifests/policyservice.yaml"
```
## Maintainers
This TeraFlowSDN service is implemented by [UBITECH](www.ubitech.eu).
Feel free to contact Georgios Katsikas (gkatsikas at ubitech dot eu) in case you have questions.
