Verifying pod is created: |
``` bash |
$ kubectl get pod pvpod |
NAME READY STATUS RESTARTS AGE |

### Using Dynamic Provisioning |
Using Dynamic Provisioning and Storage Classes you don't need to |
create Portworx volumes out of band and they will be created automatically. |
#### Storage Class |
Using Storage Classes objects an admin can define the different classes of Portworx Volumes |
that are offered in a cluster. Following are the different parameters that can be used to define a Portworx |
Storage Class |
* `fs`: filesystem to be laid out: none|xfs|ext4 (default: `ext4`) |
* `block_size`: block size in Kbytes (default: `32`) |
* `repl`: replication factor [1..3] (default: `1`) |
* `io_priority`: IO Priority: [high|medium|low] (default: `low`) |
* `snap_interval`: snapshot interval in minutes, 0 disables snaps (default: `0`) |
* `aggregation_level`: specifies the number of replication sets the volume can be aggregated from (default: `1`) |
* `ephemeral`: ephemeral storage [true|false] (default `false`) |
1. Create Storage Class. |
See example: |
```yaml |
kind: StorageClass |
apiVersion: storage.k8s.io/v1beta1 |
metadata: |
name: portworx-io-priority-high |
provisioner: kubernetes.io/portworx-volume |
parameters: |
repl: "1" |
snap_interval: "70" |
io_priority: "high" |
``` |
[Download example](portworx-volume-sc-high.yaml?raw=true) |
Creating the storageclass: |
``` bash |
$ kubectl create -f examples/volumes/portworx/portworx-volume-sc-high.yaml |
``` |
Verifying storage class is created: |
``` bash |
$ kubectl describe storageclass portworx-io-priority-high |
Name: portworx-io-priority-high |
IsDefaultClass: No |
Annotations: <none> |
Provisioner: kubernetes.io/portworx-volume |
Parameters: io_priority=high,repl=1,snapshot_interval=70 |
No events. |
``` |
2. Create Persistent Volume Claim. |
See example: |
```yaml |
kind: PersistentVolumeClaim |
apiVersion: v1 |
metadata: |
name: pvcsc001 |
annotations: |
volume.beta.kubernetes.io/storage-class: portworx-io-priority-high |
spec: |
accessModes: |
- ReadWriteOnce |
resources: |
requests: |
storage: 2Gi |
``` |
[Download example](portworx-volume-pvcsc.yaml?raw=true) |
Creating the persistent volume claim: |
``` bash |
$ kubectl create -f examples/volumes/portworx/portworx-volume-pvcsc.yaml |
``` |
Verifying persistent volume claim is created: |
``` bash |
$ kubectl describe pvc pvcsc001 |
