This is a special case that both kubelet and the volume driver should support, because users might expect it. One Kubernetes mechanism to deploy pods like this is via pod affinity. However, strictly speaking the CSI spec does not allow this usage mode (see https://github.com/container-storage-interface/spec/pull/150) and there is an on-going debate to enable it (see https://github.com/container-storage-interface/spec/issues/178). Therefore this test gets skipped unless explicitly enabled for a driver. CSI drivers which create a block device for a remote volume in NodePublishVolume fail this test. They have to make the volume available in NodeStageVolume and then in NodePublishVolume merely do a bind mount (as for example in https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver/blob/master/pkg/gce-pd-csi-driver/node.go#L150).

/*

|
* This file defines various csi volume test drivers for TestSuites.
|
|
*
|
|
* There are two ways, how to prepare test drivers:
|
|
* 1) With containerized server (NFS, Ceph, Gluster, iSCSI, ...)
|
|
* It creates a server pod which defines one volume for the tests.
|
|
* These tests work only when privileged containers are allowed, exporting
|
|
* various filesystems (NFS, GlusterFS, ...) usually needs some mounting or
|
|
* other privileged magic in the server pod.
|
|
*
|
|
* Note that the server containers are for testing purposes only and should not
|
|
* be used in production.
|
|
*
|
|
* 2) With server or cloud provider outside of Kubernetes (Cinder, GCE, AWS, Azure, ...)
|
|
* Appropriate server or cloud provider must exist somewhere outside
|
|
* the tested Kubernetes cluster. CreateVolume will create a new volume to be
|
|
* used in the TestSuites for inlineVolume or DynamicPV tests.
