如何配置Docker容器以使用Kubernetes Client API

Question

我使用Java Kubernetes Client API在集群中创建一个pod

@PostMapping(value = "/pod/add")
public V1Pod deployPod() throws IOException, ApiException{

    ApiClient client = Config.defaultClient();
    Configuration.setDefaultApiClient(client);


    CoreV1Api api = new CoreV1Api();


    V1ObjectMeta meta = new V1ObjectMeta();
    meta.name("ms2-pod");
    Map<String, String> labels = new HashMap<>();
    labels.put("app", "ms2-pod");
    meta.labels(labels);


    V1ContainerPort port = new V1ContainerPort();
    port.containerPort(9090);

    V1Container container = new V1Container();
    container.name("ms2-container");
    container.image("ms2");
    container.imagePullPolicy("IfNotPresent");
    container.ports(Arrays.asList(port));


    V1PodSpec spec = new V1PodSpec();
    spec.containers(Arrays.asList(container));

    V1Pod podBody = new V1Pod();
    podBody.apiVersion("v1");
    podBody.kind("Pod");
    podBody.metadata(meta);
    podBody.spec(spec);


    V1Pod pod = api.createNamespacedPod("default", podBody, null, null, null);

    return pod;

}

所以在运行docker容器并调用EndPoint [url = / pod / add]

时出现错误

  

java.net.ConnectException：无法连接到localhost / 127.0.0.1：8080“

注意：我可以正常使用其他不使用API​​的端点
