Kubernetes issue with user permission

Citrus Version 3.3.0

Question Hi, i am trying to test a Kubernetes client.I use the default Fabric8 Kubernetes Client that is supported by Citrus v3.3.0:

@Configuration
public class EndpointConfig {
    @Bean
    public KubernetesClient k8sClient() {
        return new KubernetesClientBuilder()
                .build();
	}		
}	

And these are my tests

public class SampleConnectionToKubernetesIT extends TestNGCitrusSpringSupport {

    @CitrusEndpoint
    private KubernetesClient k8sClient;

    @CitrusResource
    private TestContext context;


    // This works
    @Test(priority = 1, description = "TestInfo")
    @CitrusTest
    public void TestInfo() {
        run(kubernetes().info()
                .validate((info, context) -> Assert.assertEquals(info.getResult().getApiVersion(), "v1")));
    }

 
    // This returns the exception below
    @Test(priority = 2, description = "TestPods")
    @CitrusTest
    public void TestPods() {
        run(kubernetes()
                .client(k8sClient)
                .pods()
                .list()
                .validate("$..status.phase", "Running"));
    }
  
}

The exception for the “TestPods” test is the below:

ERROR LoggingReporter:267 - TEST FAILED SampleConnectionToKubernetesIT.listPodsTest <com.ccneb.ssv> Nested exception is:

(myurl and myuser are placeholders)

I saw that the kubernetes client embedded in Citrus is really outdated (v1.4.34) since the official fabric8 kubernetes client now is v6.1.1.

What I’ve tried so far I have tried add explicity the Fabric8 kubernetes client v2.0.6 and higher but the execution does not start at all, since it fails in Citrus beforeSuite method.

This is the exception:

Any ideas how to overcome the issue?

we really need to update the Kubernetes client library! I am pretty sure that the Kubernetes API has evolved a lot and the client needs to be updated.
