Java client for the kubernetes API.
To install the Java client library to your local Maven repository, simply execute:
git clone --recursive https://github.com/kubernetes-client/java
cd java
mvn installRefer to the official documentation for more information.
Add this dependency to your project's POM:
<dependency>
<groupId>io.kubernetes</groupId>
<artifactId>client-java</artifactId>
<version>0.2</version>
<scope>compile</scope>
</dependency>compile 'io.kubernetes:client-java:0.2'At first generate the JAR by executing:
git clone --recursive https://github.com/kubernetes-client/java
cd java
mvn package
Then manually install the following JARs:
- target/client-java-0.2-SNAPSHOT.jar
- target/lib/*.jar
list all pods:
import io.kubernetes.client.ApiClient;
import io.kubernetes.client.ApiException;
import io.kubernetes.client.Configuration;
import io.kubernetes.client.apis.CoreV1Api;
import io.kubernetes.client.models.V1Pod;
import io.kubernetes.client.models.V1PodList;
import io.kubernetes.client.util.Config;
import java.io.IOException;
public class Example {
public static void main(String[] args) throws IOException, ApiException{
ApiClient client = Config.defaultClient();
Configuration.setDefaultApiClient(client);
CoreV1Api api = new CoreV1Api();
V1PodList list = api.listPodForAllNamespaces(null, null, null, null, null, null, null, null, null);
for (V1Pod item : list.getItems()) {
System.out.println(item.getMetadata().getName());
}
}
}watch on namespace object:
import com.google.gson.reflect.TypeToken;
import io.kubernetes.client.ApiClient;
import io.kubernetes.client.ApiException;
import io.kubernetes.client.Configuration;
import io.kubernetes.client.apis.CoreV1Api;
import io.kubernetes.client.models.V1Namespace;
import io.kubernetes.client.util.Config;
import io.kubernetes.client.util.Watch;
import java.io.IOException;
public class WatchExample {
public static void main(String[] args) throws IOException, ApiException{
ApiClient client = Config.defaultClient();
Configuration.setDefaultApiClient(client);
CoreV1Api api = new CoreV1Api();
Watch<V1Namespace> watch = Watch.createWatch(
client,
api.listNamespaceCall(null, null, null, null, null, 5, null, null, Boolean.TRUE, null, null),
new TypeToken<Watch.Response<V1Namespace>>(){}.getType());
for (Watch.Response<V1Namespace> item : watch) {
System.out.printf("%s : %s%n", item.type, item.object.getMetadata().getName());
}
}
}More examples can be found in examples folder. To run examples, run this command:
mvn exec:java -Dexec.mainClass="io.kubernetes.client.examples.Example"All APIs and Models' documentation can be found at the Generated client's README file
| Kubernetes 1.4 | Kubernetes 1.5 | Kubernetes 1.6 | Kubernetes 1.7 | Kubernetes 1.8 | |

Key:
✓Exactly the same features / API objects in both java-client and the Kubernetes version.+java-client has features or api objects that may not be present in the Kubernetes cluster, but everything they have in common will work.-The Kubernetes cluster has features the java-client library can't use (additional API objects, etc).
See the CHANGELOG for a detailed description of changes between java-client versions.
