|
Create ReadWriteOnce 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 show an example of creating two 1GB |PVCs| with
|
|
ReadWriteOnce accessMode.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
|
|
.. _storage-configuration-create-readwriteonce-persistent-volume-claims-d891e32:
|
|
|
|
#. Create the **rwo-test-claim1** Persistent Volume Claim.
|
|
|
|
|
|
#. Create a yaml file defining the claim and its attributes.
|
|
|
|
For example:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ cat <<EOF > rwo-claim1.yaml
|
|
kind: PersistentVolumeClaim
|
|
apiVersion: v1
|
|
metadata:
|
|
name: rwo-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 rwo-claim1.yaml
|
|
|
|
persistentvolumeclaim/rwo-test-claim1 created
|
|
|
|
#. Create the **rwo-test-claim2** Persistent Volume Claim.
|
|
|
|
|
|
#. Create a yaml file defining the claim and its attributes.
|
|
|
|
For example:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ cat <<EOF > rwo-claim2.yaml
|
|
kind: PersistentVolumeClaim
|

persistentvolumeclaim/rwo-test-claim2 created

|
|
.. rubric:: |result|
|
|
|
|
Two 1Gb |PVCs| have been created. You can view the |PVCs| using
|
|
the following command.
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ kubectl get persistentvolumeclaims
