# Koordinator Java Client
Java client for the [Koordinator](https://koordinator.sh/) API.
## Usage
Add this dependency to your project's POM:
```xml
sh.koordinator
client-java
1.3.0
```
**Note that this package has not been uploaded to the maven official repository. Currently, you should manually download this repo and package it to use.**
You should also add the dependency of Kubernetes official java SDK:
```xml
io.kubernetes
client-java
16.0.2
```
### Manually package
At first generate the JAR by executing:
mvn package
Then manually install the following JARs:
* target/client-java-1.3.0.jar

KubernetesApiResponse response = reservationClient.create(reservation);
System.out.println(response.getStatus());
System.out.println(response.getObject());
assert reservation.getMetadata() != null;
reservationClient.delete(reservation.getMetadata().getName());
}
}
