While using the go-client API after I use the api.PersistentVolumeClaims(namespace).Create(createOpts) call the PersistentVolumeClaim appears as a resource but stays in the Pending state. I do not see any events when using kubectl describe pvc, I also don't see any Volumes being created etc.

$ kubectl describe pvc --namespace=test -R
Name:          93007732-9d8c-406e-be99-f48faed3a061

The code I am using is as follows:

        volume, errGo := uuid.NewRandom()                                                                                                                                                 
        if errGo != nil {                                                                                                                                                                 
                job.failed = kv.Wrap(errGo).With("stack", stack.Trace().TrimRuntime())                                                                                                    
                return job.failed                                                                                                                                                         
        }                                                                                                                                                                                 
        job.volume = volume.String()

        fs := v1.PersistentVolumeFilesystem
        createOpts := &v1.PersistentVolumeClaim{
                ObjectMeta: metav1.ObjectMeta{
                        Name:      job.volume,
                        Namespace: job.namespace,
                        UID:       types.UID(job.volume),
                },
                Spec: v1.PersistentVolumeClaimSpec{
                        AccessModes: []v1.PersistentVolumeAccessMode{v1.ReadWriteOnce},
                        Resources: v1.ResourceRequirements{
                                Requests: v1.ResourceList{
                                        v1.ResourceName(v1.ResourceStorage): resource.MustParse("10Gi"),
                                },
                        },
                        VolumeName: job.volume,
                        VolumeMode: &fs,
                },
                Status: v1.PersistentVolumeClaimStatus{
                        Phase:       v1.ClaimBound,
                        AccessModes: []v1.PersistentVolumeAccessMode{v1.ReadWriteOnce},
                        Capacity: v1.ResourceList{
                                v1.ResourceName(v1.ResourceStorage): resource.MustParse("10Gi"),
                        },
                },
        }

        api := Client().CoreV1()
        if _, errGo = api.PersistentVolumeClaims(namespace).Create(createOpts); errGo != nil {
                job.failed = kv.Wrap(errGo).With("stack", stack.Trace().TrimRuntime())
                return job.failed
        }

I have tried to find good examples for using the Create API with persistent volumes but most examples appear to be for watchers etc and so I spent quite sometime trying to reverse engineer code leading me explicitly setting the Status but this appears to have had zero impact. I also tried defaulting the VolumeMode within the Spec which did not help.

The examples I have read come from:

https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/volume/persistentvolume/framework_test.go
https://godoc.org/k8s.io/api/core/v1#PersistentVolumeSpec
https://github.com/vladimirvivien/k8s-client-examples/tree/master/go/pvcwatch
https://medium.com/programming-kubernetes/building-stuff-with-the-kubernetes-api-part-4-using-go-b1d0e3c1c899

Does anyone know of actually example code for these APIs that goes beyond unit testing within the _test.go files, or can anyone provide any hints as to how to get the creation process actually rolling within the cluster ? I have assumed that the downstream resources needed for example the Volume etc are automatically provisioned when I attempt to create the Claim resource.

Many Thanks for taking a look if you got this far...
