Installing IBM Spectrum Scale Container Storage Interface driver using CLIs

Before you install IBM Spectrum Scale Container Storage Interface driver, ensure that the prerequisites are met. For more information, see Performing pre-installation tasks.

Note: This procedure is applicable for both Kubernetes and Red Hat® OpenShift®. For Red Hat OpenShift, replace "kubectl" with "oc" in all the commands.

Installing IBM Spectrum Scale Container Storage Interface driver by using Operator involves the following phases:

Deploy the Operator on your cluster.
Use the Operator for deploying IBM Spectrum Scale Container Storage Interface driver.

Phase 1: Deploying the Operator

To deploy Operator on your cluster, do the following steps:

Create a namespace.

kubectl create namespace ibm-spectrum-scale-csi-driver

Note: For Red Hat OpenShift, use this command.

oc new-project ibm-spectrum-scale-csi-driver

Download the operator manifest.

For CSI 2.6.0, issue the following command:

curl -O https://raw.githubusercontent.com/IBM/ibm-spectrum-scale-csi/v2.6.0/generated/installer/ibm-spectrum-scale-csi-operator.yaml

For CSI 2.6.1, issue the following command:

curl -O https://raw.githubusercontent.com/IBM/ibm-spectrum-scale-csi/v2.6.1/generated/installer/ibm-spectrum-scale-csi-operator.yaml

If you are using an OCP cluster with RHEL nodes, issue the following command for CSI 2.6.0:

curl -O https://raw.githubusercontent.com/IBM/ibm-spectrum-scale-csi/v2.6.0/generated/installer/ibm-spectrum-scale-csi-operator-ocp-rhel.yaml

If you are using an OCP cluster with RHEL nodes, issue the following command for CSI 2.6.1:

curl -O https://raw.githubusercontent.com/IBM/ibm-spectrum-scale-csi/v2.6.1/generated/installer/ibm-spectrum-scale-csi-operator-ocp-rhel.yaml

Note: See Offline Installation and Upgrade for additional steps required for offline upgrade.

Issue the following command to apply the operator manifest to deploy the operator.
```
kubectl create -f ibm-spectrum-scale-csi-operator.yaml
```
For OCP cluster with RHEL nodes, issue the following command:
```
kubectl create -f ibm-spectrum-scale-csi-operator-ocp-rhel.yaml
```

Verify that the Operator is deployed, and the Operator pod is in running state.

kubectl get pod,deployment -n ibm-spectrum-scale-csi-driver


NAME                                                   READY   STATUS    RESTARTS    AGE
pod/ibm-spectrum-scale-csi-operator-6ff9cf6979-v5g4c   1/1     Running      0        6d3h

NAME                                                   READY   UP-TO-DATE  AVAILABLE AGE
deployment.apps/ibm-spectrum-scale-csi-operator        1/1        1            1     6d3h

Phase 2: Deploying IBM Spectrum Scale Container Storage Interface driver

Now that the Operator is up and running, you must access the Operator's API and request a deployment by using the CSIScaleOperator custom resource.

Do the following steps:

Create a secret with IBM Spectrum Scale GUI server’s credentials in the ibm-spectrum-scale-csi-driver namespace. For more information, see Secrets.
Note: If you are using a remote cluster setup, then create a secret object for the GUI server of each cluster.

Download the sample custom resource file on your cluster.

curl -O https://raw.githubusercontent.com/IBM/ibm-spectrum-scale-csi/v2.6.0/operator/config/samples/csiscaleoperators.csi.ibm.com_cr.yaml

Modify the parameters in the file to suit your environment. For more information, see Operator.
Apply the custom resource file to deploy IBM Spectrum Scale Container Storage Interface driver.
```
kubectl apply -f csiscaleoperators.csi.ibm.com_cr.yaml
```

Verify that the IBM Spectrum Scale Container Storage Interface driver is installed, Operator and driver resources are ready, and pods are in running state.


kubectl get pod,daemonset,deployment -n ibm-spectrum-scale-csi-driver
