Examples with Watch org.apache.flink.kubernetes.kubeclient.KubernetesSharedWatcher.Watch used on opensource projects

Example 1 with Watch

use of org.apache.flink.kubernetes.kubeclient.KubernetesSharedWatcher.Watch in project flink by apache.

the class KubernetesSharedInformerITCase method testWatchWithBlockHandler.

@Test
public void testWatchWithBlockHandler() throws Exception {
    try (KubernetesConfigMapSharedWatcher watcher = client.createConfigMapSharedWatcher(labels)) {
        final String configMapName = getConfigMapName(System.currentTimeMillis());
        final long block = 500;
        final long maxUpdateVal = 30;
        final TestingBlockCallbackHandler handler = new TestingBlockCallbackHandler(block, maxUpdateVal);
        final Watch watch = watcher.watch(configMapName, handler, watchCallbackExecutorService);
        createConfigMap(configMapName);
        for (int i = 1; i <= maxUpdateVal; i++) {
            updateConfigMap(configMapName, ImmutableMap.of("val", String.valueOf(i)));
        }
        try {
            handler.expectedFuture.get(120, TimeUnit.SECONDS);
        } catch (TimeoutException e) {
            fail("expected value: " + maxUpdateVal + ", actual: " + handler.val);
        }
        try {
            handler.assertFuture.get(2 * block, TimeUnit.MILLISECONDS);
        } catch (TimeoutException e) {
        // expected
        }
        watch.close();
    }
}

Example 2 with Watch

use of org.apache.flink.kubernetes.kubeclient.KubernetesSharedWatcher.Watch in project flink by apache.

the class KubernetesSharedInformerITCase method watchInRange.

private void watchInRange(KubernetesConfigMapSharedWatcher watcher, List<TestingCallbackHandler> callbackHandlers, List<Watch> watchers, int start, int end) {
    for (int i = start; i < end; i++) {
        final String name = getConfigMapName(i % 10);
        final TestingCallbackHandler handler = new TestingCallbackHandler(name);
        callbackHandlers.add(handler);
        final Watch watch = watcher.watch(name, handler, watchCallbackExecutorService);
        watchers.add(watch);
    }
}
