This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

Create ReadWriteMany 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
|
|
volume obtained with a Persistent Volume Claim (PVC) created to provide
|
|
persistent storage.
|
|
|
|
.. rubric:: |context|
|
|
|
|
For multiple containers to mount the same PVC, create a PVC with accessMode of
|
|
ReadWriteMany (RWX).
|
|
|
|
The following steps show an example of creating a 1GB |PVC|
|
|
with ReadWriteMany accessMode.

|
|
|
|
#. Create the **rwx-test-claim** Persistent Volume Claim.
|
|
|
|
#. Create a yaml file defining the claim and its attributes. For example:
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ cat <<EOF > rwx-claim.yaml
|
|
kind: PersistentVolumeClaim

name: rwx-test-claim

spec:
|

accessModes:
|
|
- ReadWriteMany
|
|
resources:
|
|
requests:
|
|
storage: 1Gi

|
storageClassName: cephfs
|

EOF
|
|
|
|
#. Apply the settings created above.
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ kubectl apply -f rwx-claim.yaml
|
|
persistentvolumeclaim/rwx-test-claim created
|
|
|
|
1GB PVC has been created. You can view the PVCs using the following command.
|
|
|
|
.. code-block:: none
|
|
|
|
~(keystone_admin)]$ kubectl get persistentvolumeclaims
