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.

  1. 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
  2. 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:

  1. 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
  2. Apply the storageclass.yaml file:

    kubectl apply -f storageclass.yaml
