→‎Storage using Volumes
Regel 287: Regel 287:


Make sure the other nodes can access it, by checking that <code>mkdir /persistent && mount -t nfs <ipaddress>:/persistent /persistent</code> works.
Make sure the other nodes can access it, by checking that <code>mkdir /persistent && mount -t nfs <ipaddress>:/persistent /persistent</code> works.
Now, we can create a PersistentVolume for this NFS mount using the following YAML file:
<pre>
apiVersion: v1
kind: PersistentVolume
metadata:
  name: mypersistentvolume
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: slow
  mountOptions:
    - hard
    - nfsvers=4.1
  nfs:
    path: /persistent
    server: <ipaddress>
</pre>
And we'll need to make a PersistentVolumeClaim to claim the volume for our node:
<pre>
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: myclaim
spec:
  accessModes:
    - ReadWriteMany
  volumeMode: Filesystem
  resources:
    requests:
      storage: 5Gi
  storageClassName: slow
  selector:
    matchLabels:
      release: "stable"
    matchExpressions:
      - {key: environment, operator: In, values: [dev]}
</pre>


Now we can go ahead and create our pod with this volume:
