Example 1 with Lister

use of io.kubernetes.client.informer.cache.Lister in project java by kubernetes-client.

the class InformerExample method main.

public static void main(String[] args) throws Exception {

    ApiClient apiClient = coreV1Api.getApiClient();
    OkHttpClient httpClient = apiClient.getHttpClient().newBuilder().readTimeout(0, TimeUnit.SECONDS).build();

    SharedInformerFactory factory = new SharedInformerFactory(apiClient);
    // Node informer
    SharedIndexInformer<V1Node> nodeInformer = factory.sharedIndexInformerFor(// the informer-factory.
    (CallGeneratorParams params) -> {
        return coreV1Api.listNodeCall(null, null, null, null, null, null, params.resourceVersion, null, params.timeoutSeconds, params.watch, null);
    }, V1Node.class, V1NodeList.class);
    nodeInformer.addEventHandler(new ResourceEventHandler<V1Node>() {

        @Override
