HPE and Red Hat have a long standing partnership to provide jointly supported software, platform and services with the absolute best customer experience in the industry.
Red Hat OpenShift uses open source Kubernetes and various other components to deliver a PaaS experience that benefits both developers and operations. This packaged experience differs slighty on how you would deploy and use the HPE volume drivers and this page serves as the authoritive source for all things HPE primary storage and Red Hat OpenShift.
Software deployed on OpenShift 4 follows the Operator pattern. CSI drivers are no exception.
Software delivered through the HPE and Red Hat partnership follows a rigorous certification process and only qualify what's listed in the following table.
|Status||Red Hat OpenShift||HPE CSI Operator||Container Storage Providers|
|Certified||4.2||1.2.0||Nimble, 3PAR and Primera|
|Certified||4.3||1.2.0||Nimble, 3PAR and Primera|
|Certified||4.3, 4.4||1.3.0||Nimble, 3PAR and Primera|
Check this table periodically for future releases.
Other combinations may work but will not be supported.
Both Red Hat Enterprise Linux and Red Hat CoreOS worker nodes are supported.
The HPE CSI Operator for Kubernetes needs to be installed through the interfaces provided by Red Hat. Do not follow the instructions found on OperatorHub.io.
The HPE CSI Driver needs to run in privileged mode and needs access to host ports, host network and should be able to mount hostPath volumes. Hence, before deploying HPE CSI Operator on OpenShift, please create the following
SecurityContextConstraints (SCC) to allow the CSI driver to be running with these privileges.
Download the SCC to where you have access to
oc and the OpenShift cluster:
curl -sL https://raw.githubusercontent.com/hpe-storage/co-deployments/master/operators/hpe-csi-operator/deploy/scc.yaml > hpe-csi-scc.yaml
my-hpe-csi-operator to the name of the project (e.g.
hpe-csi-driver below) where the CSI Operator is being deployed.
oc new-project hpe-csi-driver --display-name="HPE CSI Driver for Kubernetes" sed -i 's/my-hpe-csi-operator/hpe-csi-driver/g' hpe-csi-scc.yaml
Deploy the SCC:
oc create -f hpe-csi-scc.yaml securitycontextconstraints.security.openshift.io/hpe-csi-scc created
Make note of the project name as it's needed for the Operator deployment in the next steps.
At this time of writing (CSI Operator 1.2.0) the default
StorageClass being shipped with the CSI driver is not very useful for OpenShift as it doesn't allow applications to write in the
PersistentVolumes. Make sure to deploy a new
.parameters.fsMode set to
"0770". This caveat will be removed in subsequent releases.
- Learn how to create a base
StorageClassin using the CSI driver.
This provides an example Operator deployment using
oc. If you want to use the web console, proceed to the next section.
It's assumed the SCC has been applied to the project and have
kube:admin privileges. As an example, we'll deploy to the
hpe-csi-driver project as described in previous steps.
OperatorGroup needs to be created.
apiVersion: operators.coreos.com/v1 kind: OperatorGroup metadata: name: hpe-csi-driver-for-kubernetes namespace: hpe-csi-driver spec: targetNamespaces: - hpe-csi-driver
Next, create a
Subscription to the Operator.
apiVersion: operators.coreos.com/v1alpha1 kind: Subscription metadata: name: hpe-csi-operator namespace: hpe-csi-driver spec: channel: stable name: hpe-csi-operator source: certified-operators sourceNamespace: openshift-marketplace
The Operator will now be installed on the OpenShift cluster. Before instantiating a CSI driver, watch the rollout of the Operator.
oc rollout status deploy/hpe-csi-operator -n hpe-csi-driver Waiting for deployment "hpe-csi-operator" rollout to finish: 0 of 1 updated replicas are available... deployment "hpe-csi-operator" successfully rolled out
The next step is to create a
HPECSIDriver object. It's unique per backend CSP.
apiVersion: storage.hpe.com/v1 kind: HPECSIDriver metadata: name: csi-driver namespace: hpe-csi-driver spec: backendType: nimble imagePullPolicy: Always logLevel: info secret: backend: 192.168.1.1 create: true password: admin servicePort: '8080' username: admin storageClass: allowVolumeExpansion: true create: true defaultClass: false name: hpe-standard parameters: accessProtocol: iscsi fsType: xfs volumeDescription: Volume created by the HPE CSI Driver for Kubernetes
apiVersion: storage.hpe.com/v1 kind: HPECSIDriver metadata: name: csi-driver namespace: hpe-csi-driver spec: backendType: primera3par imagePullPolicy: Always logLevel: info secret: backend: 10.10.10.1 create: true password: 3pardata servicePort: '8080' username: 3paradm storageClass: allowVolumeExpansion: true create: true defaultClass: false name: hpe-standard parameters: accessProtocol: iscsi fsType: xfs volumeDescription: Volume created by the HPE CSI Driver for Kubernetes
OpenShift web console¶
Once the SCC has been applied to the project, login to the OpenShift web console as
kube:admin and navigate to Operators -> OperatorHub.
Search for 'HPE' in the search field.
Select the HPE CSI Operator and click 'Install'.
In the next pane, click 'Subscribe'.
The HPE CSI Operator is now installed.
Click the HPE CSI Operator, in the next pane, click 'Create Instance'.
Configure the instance with the desired values!.
The required parameters are
.spec.secret.backend and the credentials for the backend (
By navigating to the Developer view, it should now be possible to inspect the CSI driver and Operator topology.
At this point the CSI driver is managed like any other Operator on Kubernetes and the life-cycle management capabilities may be exlored further in the official Red Hat OpenShift documentation.
Customers still using OpenShift 3 may use any of the legacy FlexVolume drivers for managing persistent storage.
