How do I control a kubernetes PersistentVolumeClaim to bind to a specific PersistentVolume?
<p>I have multiple volumes and one claim. How can I tell the claim to which volume to bind to?</p>

<p>How does a <code>PersistentVolumeClaim</code> know to which volume to bind? Can I controls this using some other parameters or metadata?</p>

<p>I have the following <code>PersistentVolumeClaim</code>:</p>

<p>If I create the claim and the volume using:</p>

<pre><code>kubectl create -f pvc.json -f pv.json
</code></pre>

<p>I get the following listing of the volumes and claims:</p>

<pre><code>NAME                 LABELS                    CAPACITY   ACCESSMODES   STATUS    CLAIM                         REASON    AGE
default-drive-disk   name=default-drive-disk   10Gi       RWO           Bound     default/default-drive-claim             2s
NAME                  LABELS    STATUS    VOLUME               CAPACITY   ACCESSMODES   AGE
default-drive-claim   &lt;none&gt;    Bound     default-drive-disk   10Gi       RWO           2s
</code></pre>

<p>How does the claim know to which volume to bind?</p>
