Example

list all pods:

import com.kubedb.client.ApiClient;
import com.kubedb.client.ApiException;
import com.kubedb.client.Configuration;
import com.kubedb.client.apis.KubedbComV1alpha1Api;
import com.kubedb.client.models.V1alpha1Redis;
import com.kubedb.client.models.V1alpha1RedisList;
import com.kubedb.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);

    KubedbComV1alpha1Api api = new KubedbComV1alpha1Api();
    V1alpha1RedisList list =
        api.listRedisForAllNamespaces(null, null, null, null, null, null, null, null, null);
    for (V1alpha1Redis item : list.getItems()) {
      System.out.println(item.getMetadata().getName());
    }
  }
}

watch on redis object:

import com.google.gson.reflect.TypeToken;
import com.kubedb.client.ApiClient;
import com.kubedb.client.ApiException;
import com.kubedb.client.Configuration;
import com.kubedb.client.apis.KubedbComV1alpha1Api;
import com.kubedb.client.models.V1alpha1Redis;
import com.kubedb.client.util.Config;
import com.kubedb.client.util.Watch;
import java.io.IOException;
import java.util.concurrent.TimeUnit;

public class WatchExample {
  public static void main(String[] args) throws IOException, ApiException {
    ApiClient client = Config.defaultClient();
    client.getHttpClient().setReadTimeout(60, TimeUnit.SECONDS);
    Configuration.setDefaultApiClient(client);

    KubedbComV1alpha1Api api = new KubedbComV1alpha1Api();

    Watch<V1alpha1Redis> watch =
        Watch.createWatch(
            client,
            api.listRedisForAllNamespacesCall(
                null, null, null, null, null, "false", null, null, Boolean.TRUE, null, null),
            new TypeToken<Watch.Response<V1alpha1Redis>>() {}.getType());

    for (Watch.Response<V1alpha1Redis> 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:

Compatibility

	Kubernetes 1.4	Kubernetes 1.5	Kubernetes 1.6	Kubernetes 1.7	Kubernetes 1.8	Kubernetes 1.9
1.0	+	+	+	+	✓	-

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.
