<p>I'm trying to use kubernetes with a spring boot application and use mysql. But i found this error on minikube dashboard:</p>
<pre><code>0/1 nodes are available: 1 pod has unbound immediate PersistentVolumeClaims.Back-off restarting failed container    
</code></pre>
<p>A secret file is created for boath user and admin and a configMap file also to map the spring boot image to the service of mysql.
Mysql deployement file is:</p>

<p>I'm new with kubernetes and I can't find solution.</p>

<p>You need to create a PV to satisfy the PVC. If you apply the below PV it should work.</p>
<pre><code>apiVersion: v1
kind: PersistentVolume
metadata:
  name: task-pv-volume
  labels:
    type: local
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: &quot;/mnt/data&quot;
</code></pre>
<p>Please note below points</p>
<ol>
<li>Usage of <code>hostPath</code> is not recommended in production</li>
<li><code>capacity</code> of PV and PVC needs to match</li>
<li><code>accessModes</code> of PV and PVC needs to match</li>
</ol>
