使用 java 客户端从 Kubernetes 命名空间中删除轮廓 httpproxy

Question

I am working on the K8s implementation using kubernetes java client. I am looking for the solution to delete Contour HTTPProxy which are in invalid state. However I am not able to figure out how to do it with help of Java Client.

I am aware that we can delete the ingress using below code

k8sClient.extensions().ingresses().withName("my-ingress").delete();

Any help on how to delete Contour HTTPProxy object from K8s namespace using java client will be appreciated?

Contour HTTPProxy seems to be a custom resource . You can either use our typed(required CustomResource POJOs) or typeless API(CustomResource manipulation using raw maps) for deleting HTTPProxy.

Here is an example of doing it using the typeless API(based on KubernetesClient v5.4.1):

try (KubernetesClient client = new DefaultKubernetesClient()) {
    CustomResourceDefinitionContext context = new CustomResourceDefinitionContext.Builder()
            .withKind("HTTPProxy")
            .withPlural("httpproxies")
            .withGroup("projectcontour.io")
            .withVersion("v1")
            .withScope("Namespaced")
            .build();

    boolean isDeleted = client.customResource(context).inNamespace("default").withName("root").delete();
    if (!isDeleted) {
        logger.warn("Unable to Delete HTTPProxy {} in {} namespace", "root", "default");
    }
    logger.info("HTTPProxy {} successfully deleted.", "root");
} catch (KubernetesClientException exception) {
    logger.error("Exception in interacting with Kubernetes API", exception);
}
