How to create ingress in Kubernetes V1.23.1 version ?

See original GitHub issue

I referred to the sample code, but it did not compile successfully. I am using Kubernetes-Client version 5.12.1

Ingress ingress = new IngressBuilder() .withNewMetadata().withName("test-ingress").addToAnnotations("nginx.ingress.kubernetes.io/rewrite-target", "/").endMetadata() .withNewSpec() .addNewRule() .withNewHttp() .addNewPath() .withPath("/testPath").withNewBackend().withServiceName("test").withServicePort(new IntOrString(80)).endBackend() .endPath() .endHttp() .endRule() .endSpec() .build(); client.network().ingress().inNamespace("default").create(ingress);

But I compiled successfully in V4.12.0 using the following methods: client.extensions().ingresses().createorreplace (ingress);

The error message is related to PUT performed by createOrReplace. See #3896 and related issues. Fabric8 6 will have basic support for server side apply #3334 - until then you may want to use something like:

// build the ingress keeping the other parts of the existing spec
Ingress buildOrEdit(IngressBuilder builder) {
  return builder.withNewMetadata().withName("test-ingress").addToAnnotations("nginx.ingress.kubernetes.io/rewrite-target", "/").endMetadata()
                .editOrNewSpec()
                .withRules(new IngressRuleBuilder()
                .withNewHttp()
                .addNewPath().withPathType("Prefix")
                .withPath("/"+"fims-web"+"/(.+)").withBackend(new IngressBackend())
                .endPath()
                .endHttp()
                .build())
                .endSpec()
                .build();
}

var ingresses = client.network().v1().ingresses().inNamespace("default");

try {
  ingresses.edit(i -> buildOrEdit(new IngressBuilder(i)));
} catch (KubernetesClientException e) {
  if (e.getCode() != 404) {
    throw e;
  }
  ingresses.create(buildOrEdit(new IngressBuilder());
}

This avoids a PUT on replace and when the diff is computed for an edit the buildOrEdit function will make sure that generated fields are retained.
