## Portworx |
[Portworx](http://www.portworx.com) can be used as a storage provider for your Kubernetes cluster. Portworx pools your servers capacity and turns your servers |
or cloud instances into converged, highly available compute and storage nodes |
## Prerequisites |
- A Portworx instance running on all of your Kubernetes nodes. For |
more information on how you can install Portworx can be found [here](http://docs.portworx.com) |
## Examples |
The following examples assumes that you already have a running Kubernetes cluster with Portworx installed on all nodes. |
### Using Pre-provisioned Portworx Volumes |
Create a Volume using Portworx CLI. |
On one of the Kubernetes nodes with Portworx installed run the following command |
```shell |
/opt/pwx/bin/pxctl volume create <vol-id> --size <size> --fs <fs-type> |
``` |
#### Running Pods |
Create Pod which uses Portworx Volumes |
Example spec: |
```yaml |
apiVersion: v1 |
kind: Pod |
metadata: |
name: test-portworx-volume-pod |
spec: |
containers: |
- image: registry.k8s.io/test-webserver |
name: test-container |
volumeMounts: |
- mountPath: /test-portworx-volume |
name: test-volume |
volumes: |
- name: test-volume |
# This Portworx volume must already exist. |
portworxVolume: |
volumeID: "<vol-id>" |
fsType: "<fs-type>" |
``` |
[Download example](portworx-volume-pod.yaml?raw=true) |
Make sure to replace <vol-id> and <fs-type> in the above spec with |
the ones that you used while creating the volume. |
Create the Pod. |
``` bash |
$ kubectl create -f examples/volumes/portworx/portworx-volume-pod.yaml |
``` |
Verify that pod is running: |
```bash |
$ kubectl.sh get pods |
NAME READY STATUS RESTARTS AGE |
test-portworx-volume-pod 1/1 Running 0 16s |
``` |
#### Persistent Volumes |
1. Create Persistent Volume. |
Example spec: |
```yaml |
apiVersion: v1 |
kind: PersistentVolume |
metadata: |
name: <vol-id> |
spec: |
capacity: |
storage: <size>Gi |
accessModes: |
- ReadWriteOnce |
persistentVolumeReclaimPolicy: Retain |
