<p>files stored on PV persistent storage by pod application are not visible on host machine. Configuration shows no errors. Config - single pv, pvc, pod.
I am quite new to this environment.</p>

<p>pv:</p>

<pre><code>apiVersion: v1
kind: PersistentVolume
metadata:

<p>So I have no idea why aaa is not visible on the host machine in google cloud - as I think 'aaa' file should be here.</p>

<p>I think the issue is caused by on what host you examine the directory contents.</p>

<ul>
<li>You've executed the last command on the "cloudshell" VM which is only meant for interacting with GCP and is not a cluster node.</li>
<li>And you should rather inspect it on a cluster node.</li>
<li>To inspect the state of the cluster node you should do something like this:</li>
</ul>

<pre><code>$ gcloud compute instances list
