/*
|
|
* This test checks that various VolumeSources are working.
|
|
*
|
|
* There are two ways, how to test the volumes:
|
|
* 1) With containerized server (NFS, Ceph, Gluster, iSCSI, ...)
|
|
* The test creates a server pod, exporting simple 'index.html' file.
|
|
* Then it uses appropriate VolumeSource to import this file into a client pod
|
|
* and checks that the pod can see the file. It does so by importing the file
|
|
* into web server root and loadind the index.html from it.
|
|
*
|
|
* 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 outside of Kubernetes (Cinder, ...)
|
|
* Appropriate server (e.g. OpenStack Cinder) must exist somewhere outside
|
|
* the tested Kubernetes cluster. The test itself creates a new volume,
|
|
* and checks, that Kubernetes can use it as a volume.
