Null response when try to create a replicationController

[bengong2015]

It was successful when I tried to create service, but I found the function of create service does not check the http status code = 201 so that it exposed exception: 'Failed: Created'. I fixed this. When I tried to create or update a replicationControllers, a kubernetesClientException exposed : SEVERE: Replication Controller [wildfly11-rc] creation failed. Null response received. com.github.kubernetes.java.client.exceptions.KubernetesClientException: Replication Controller [wildfly11-rc] creation failed. at com.github.kubernetes.java.client.KubernetesApiClient.handleNullResponse(KubernetesApiClient.java:459) at com.github.kubernetes.java.client.KubernetesApiClient.createReplicationController(KubernetesApiClient.java:221) at com.sipm.bcf.ac.server.action.StartAppAction.createReplicationController(StartAppAction.java:62) at com.sipm.bcf.ac.server.action.StartAppAction.start(StartAppAction.java:28) at com.sipm.bcf.ac.server.action.StartAppAction.main(StartAppAction.java:93)

The method of createController: protected boolean createReplicationController(){ rc = new ReplicationController(); State desiredState = new State(); rc.setId(imageName+"-rc"); desiredState = new State(); desiredState.setReplicas(replicas); Selector selector = new Selector(); selector.setName(imageName+"-sc"); desiredState.setReplicaSelector(selector); //---------------------------------- Pod podTemplate = new Pod(); State podState = new State(); Manifest manifest = new Manifest(); manifest.setId(imageName+"-rc"); Container container = new Container(); container.setName(imageName); container.setImage(registryUrl+"/"+imageName); Port p = new Port(); p.setContainerPort(containerPort); container.setPorts(Collections.singletonList(p)); manifest.setContainers(Collections.singletonList(container)); podState.setManifest(manifest); podTemplate.setDesiredState(podState); podTemplate.setLabels(new Label(imageName+"-sc")); //----------------------------------- desiredState.setPodTemplate(podTemplate); rc.setDesiredState(desiredState); rc.setLabels(new Label(imageName+"-sc")); try { client.createReplicationController(rc); } catch (KubernetesClientException e) { e.printStackTrace(); return false; } return true; } I used api v1beta1 (endpointurl="http://202.120.11.50:8080/api/v1beta1/"). The version of kubernetes is v0.15.0. I guess it's caused by the kube-api changed some attributes of creating RC since it was failed when I tried to create RC by creating a json file with v1beta1 schema on master and create it by command which was successful in v0.6.

@bengong2015 thanks for reporting the issue. Could you send a fix as a PR? I don't have time to spend on this right now :-(
