Step 4: StorageClass Setup

In the previous section, you saved the Kubernetes token in a secret called px-user-token in the kube-system namespace. Now you can create a StorageClass which points Portworx to authenticate the request using the token in the that secret.

Portworx validates requests to manage volumes using the token saved in the secret referenced by the StorageClass. As you create more StorageClasses, remember to reference the secret with the token to authenticate the requests. The example below demonstrates a StorageClass with token secrets added:

StorageClass for CSI

When using CSI, the StorageClass references the secret for the three types of supported operations: provision, node-publish (mount/unmount), and controller-expand.

Create the following storageclass.yaml file:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: px-storage
provisioner: pxd.portworx.com
parameters:
  repl: "1"
  csi.storage.k8s.io/provisioner-secret-name: px-user-token
  csi.storage.k8s.io/provisioner-secret-namespace: kube-system
  csi.storage.k8s.io/node-publish-secret-name: px-user-token
  csi.storage.k8s.io/node-publish-secret-namespace: kube-system
  csi.storage.k8s.io/controller-expand-secret-name: px-user-token
  csi.storage.k8s.io/controller-expand-secret-namespace: kube-system
allowVolumeExpansion: true

Apply the storageclass.yaml file:
```
kubectl apply -f storageclass.yaml
```

StorageClass for non-CSI

For StorageClasses using the (now deprecated as of Kubernetes v1.25.x onward) in-tree Portworx driver, the approach to leverage PX-Security is as follows:

Create the following storageclass.yaml file:

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: px-storage
provisioner: kubernetes.io/portworx-volume
parameters:
  repl: "1"
  openstorage.io/auth-secret-name: px-user-token
  openstorage.io/auth-secret-namespace: kube-system
allowVolumeExpansion: true

Apply the storageclass.yaml file:
```
kubectl apply -f storageclass.yaml
```
