ApiClient client = Config.defaultClient();
            // infinite timeout
            OkHttpClient httpClient = client.getHttpClient().newBuilder().connectTimeout(0, TimeUnit.SECONDS)
                .readTimeout(0, TimeUnit.SECONDS).build();
            client.setHttpClient(httpClient);
            io.kubernetes.client.openapi.Configuration.setDefaultApiClient(client);
            logger.info("use inCluster mode");
            logger.info("KUBERNETES_SERVICE: "+client.getBasePath());
            return new CoreV1Api(client);
I made sure the network was working

I use the code is very simple
V1PodList list = coreV1Api.listNamespacedPod(serviceName, DEFAULT_PRETTY, false, null, null, null, null, null,
            null, 10, false);
Throws an exception

Additional context

Add any other context about the problem here.
          
It appears that you are setting your timeouts to zero seconds? I don't think that is what you want (and I suspect that is what is causing the problem)
Why are you setting timeouts, it shouldn't be needed.

That's not the point. It's the same no matter how many settings you have. I've already debugged it

            return e.getMessage();
when I use it this way, there are still mistakes
          
i use kubernetes-client
    @RequestMapping("/inNamespaceList")
    public Object test(@RequestParam(required = false, defaultValue = "luc") String namespace) {
        final ConfigBuilder configBuilder = new ConfigBuilder();
        try (KubernetesClient client = new DefaultKubernetesClient(configBuilder.build())) {
            // Creating namespace
            PodList podList = client.pods().inNamespace(namespace).list(new ListOptionsBuilder().withLimit(20L).build());
            return podList;
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
            Throwable[] suppressed = e.getSuppressed();
            if (suppressed != null) {
                for (Throwable t : suppressed) {
                    logger.error(t.getMessage(), t);
        return Collections.emptyList();
as expected, the pod list is returned
but in https://github.com/kubernetes-client/java

ConnectionShutdownException

I don't know what's going on, I've tested it from version 14-16

i use code：
    @RequestMapping("/listNamespacedPod")
    @ResponseBody
    public Object listNamespacedPod(@RequestParam(required = false, defaultValue = "luc") String namespace) {
        try {
            ApiClient client = Config.defaultClient();
            Configuration.setDefaultApiClient(client);
            CoreV1Api api = new CoreV1Api();
            V1PodList list =
                api.listNamespacedPod(namespace, "true", null, null, null, null, null, null, null, null, false);
            return list;
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
            return e.getMessage();
please help me looking ，thx all

Given the status quo, this problem is bound to arise
