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 :abbr:`PVC (Persistent Volume Claim)` created to provide
|
|
persistent storage.
|
|
|
|
.. rubric:: |context|
|
|
|
|
The following steps create two 1Gb persistent volume claims.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
.. _kubernetes-user-tutorials-creating-persistent-volume-claims-d385e32:
|
|
|
|
#. Create the **test-claim1** persistent volume claim.
|
|
|
|
|
|
#. Create a yaml file defining the claim and its attributes.
|
|
|
|
For example:
|
|
|
|
.. code-block:: yaml
|
|
|
|
~(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:: yaml
|
|
|
|
~(keystone_admin)$ cat <<EOF > claim2.yaml
|
|
kind: PersistentVolumeClaim
|
|
apiVersion: v1
|
|

|
|
name: test-claim2

|
|
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
