Portworx Encrypted Volumes
Portworx has two different kinds of encrypted volumes:
-
Encrypted Volumes
Encrypted volumes are regular volumes which can be accessed from only one node.
-
Encrypted Sharedv4 Volumes
Encrypted sharedv4 volume allows access to the same encrypted volume from multiple nodes.
Using a StorageClass parameter, you can tell Portworx to encrypt all PVCs created using that StorageClass. Portworx uses a cluster wide secret to encrypt all the volumes created using the secure StorageClass.
Step 2: Create a StorageClass
Create a storage class with the secure
parameter set to true
.
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: px-secure-sc
provisioner: pxd.portworx.com
parameters:
secure: "true"
repl: "3"
To create a sharedv4 encrypted volume set the sharedv4
parameter to true
as well.
Step 3: Create Persistent Volume Claim
Create a PVC that uses the above px-secure-sc
storage class.
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: secure-pvc
spec:
storageClassName: px-secure-sc
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2Gi
Step 4: Verify the volume
Once the PVC has been created, verify the volume created in Portworx is encrypted:
