===============================
Create Persistent Volume Claims
===============================
Container images have an ephemeral file system by default. For data to
survive beyond the lifetime of a container, it can read and write files to
a persistent volume obtained with a |PVC| created to provide persistent
storage.
.. rubric:: |context|
The following steps create two 1Gb persistent volume claims.
.. rubric:: |proc|
.. _storage-configuration-create-persistent-volume-claims-d891e32:
#. Create the **test-claim1** persistent volume claim.
#. Create a yaml file defining the claim and its attributes.
For example:
.. code-block:: none
~(keystone_admin)]$ cat <<EOF > claim1.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: test-claim1
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: general
EOF
#. Apply the settings created above.
.. code-block:: none
~(keystone_admin)]$ kubectl apply -f claim1.yaml
persistentvolumeclaim/test-claim1 created
#. Create the **test-claim2** persistent volume claim.
#. Create a yaml file defining the claim and its attributes.
For example:
.. code-block:: none
~(keystone_admin)]$ cat <<EOF > claim2.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: test-claim2
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: general
EOF
#. Apply the settings created above.
.. code-block:: none
~(keystone_admin)]$ kubectl apply -f claim2.yaml
persistentvolumeclaim/test-claim2 created
.. rubric:: |result|
Two 1Gb persistent volume claims have been created. You can view them with
the following command.
.. code-block:: none
~(keystone_admin)]$ kubectl get persistentvolumeclaims
