Install Portworx on Red Hat OpenShift Services on AWS

Prerequisites

You must have a Red Hat OpenShift Services on AWS (ROSA) cluster deployed on infrastructure that meets the minimum requirements for Portworx
Your cluster must be running OpenShift 4 or higher
Your instance size must be at least m5.xlarge with 3 compute nodes and have 3 availability zones
Your cluster must meet AWS prerequisites for ROSA
Ensure that OCP service is enabled from your AWS console
AWS CLI installed and configured
ROSA CLI installed and configured
Ensure that any underlying nodes used for Portworx in OCP have Secure Boot disabled

Configure your environment

Follow the instructions in this section to setup your environment before deploying Portworx on a Red Hat OpenShift Services on AWS (ROSA) cluster.

Create an IAM policy

Follow these instructions from your AWS IAM console to grant the required permissions to Portworx:

From the IAM page, click Roles in the left pane.
On the Roles page, type your cluster name in the search bar and press enter. Click your cluster’s worker role from the search results.
From the worker role summary page, click Add permissions on the Permissions subpage, and then click Create inline policy from the dropdown menu.

Copy and paste the following into the JSON tab text-box and click Review policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
            "Effect": "Allow",
            "Action": [
              "ec2:AttachVolume",
              "ec2:ModifyVolume",
              "ec2:DetachVolume",
              "ec2:CreateTags",
              "ec2:CreateVolume",
              "ec2:DeleteTags",
              "ec2:DeleteVolume",
              "ec2:DescribeTags",
              "ec2:DescribeVolumeAttribute",
              "ec2:DescribeVolumesModifications",
              "ec2:DescribeVolumeStatus",
              "ec2:DescribeVolumes",
              "ec2:DescribeInstances",
              "autoscaling:DescribeAutoScalingGroups"
            ],
            "Resource": [
              "*"
            ]
        }
    ]
}

Provide Name and click Create policy. Once your policy is successfully created for your cluster’s worker role, it will be listed in the Permissions policies section.

Open ports for worker nodes

Perform the following to add the inbound rules so that the AWS EC2 instance uses your specified security groups to control the incoming traffic.

From the EC2 page of your AWS console, click Security Groups, under Network & Security, in the left pane.
On the Security Groups page, type your ROSA cluster name in the search bar and press enter. You will see a list of security groups associated with your cluster. Click the link under Security group ID of your cluster’s worker security group:
From your security group page, click Actions in the upper-right corner, and choose Edit inbound rules from the dropdown menu.
Click Add Rule at the bottom of the screen to add each of the following rules:
- Allow inbound Custom TCP traffic with Protocol: TCP on ports 17001 - 17022
- Allow inbound Custom TCP traffic with Protocol: TCP on port 20048
- Allow inbound Custom TCP traffic with Protocol: TCP on port 111
- Allow inbound Custom UDP traffic with Protocol: UDP on port 17002
- Allow inbound NFS traffic with Protocol: TCP on port 2049
Make sure to specify the security group ID of the same worker security group that is mentioned in step 2.
Click Save rule.

Install Portworx

Follow the instructions in this section to deploy Portworx.

Generate Portworx spec

Navigate to PX-Central and log in, or create an account.
Select Portworx Enterprise from the Product Catalog page.
On the Product Line page, choose any option depending on which license you intend to use, then click Continue to start the spec generator.
For Platform, choose AWS. Under Distribution Name, select Red Hat OpenShift Service on AWS (ROSA). Enter your cluster’s Kubernetes version, then click Save Spec to generate the specs.

Log in to OpenShift UI

Log in to the OpenShift console by following the quick access instructions on the Accessing your cluster quickly page in the Red Hat OpenShift Service on AWS documentation.

Install Portworx Operator using the OpenShift UI

From your OpenShift console, select OperatorHub in the left pane.
On the OperatorHub page, search for Portworx and select the Portworx Enterprise or Portworx Essential card:
Click Install:
The Portworx Operator begins to install and takes you to the Install Operator page. On this page, select the A specific namespace on the cluster option for Installation mode. Select the Create Project option from the Installed Namespace dropdown:
On the Create Project window, enter the name as portworx and click Create to create a namespace called portworx.
Click Install to install Portworx Operator in the portworx namespace.

Apply Portworx spec using OpenShift UI

Once the Operator is installed successfully, create a StorageCluster object from the same page by clicking Create StorageCluster:
On the Create StorageCluster page, choose YAML view to configure a StorageCluster.
Copy and paste the above Portworx spec into the text-editor, and click Create to deploy Portworx:
Verify that Portworx has deployed successfully by navigating to the Storage Cluster tab of the Installed Operators page. Once Portworx has been fully deployed, the status will show as Online:

Verify your Portworx installation

Once you’ve installed Portworx, you can perform the following tasks to verify that Portworx has installed correctly.

Verify if all pods are running

Enter the following oc get pods command to list and filter the results for Portworx pods:

oc get pods -n portworx -o wide | grep -e portworx -e px

Note the name of one of your px-cluster pods. You’ll run pxctl commands from these pods in following steps.

Verify Portworx cluster status

You can find the status of the Portworx cluster by running pxctl status commands from a pod. Enter the following oc exec command, specifying the pod name you retrieved in the previous section:

Create your first PVC

For your apps to use persistent volumes powered by Portworx, you must use a StorageClass that references Portworx as the provisioner. Portworx includes a number of default StorageClasses, which you can reference with PersistentVolumeClaims (PVCs) you create. For a more general overview of how storage works within Kubernetes, refer to the Persistent Volumes section of the Kubernetes documentation.

Perform the following steps to create a PVC:

Create a PVC referencing the px-csi-db default StorageClass and save the file:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
    name: px-check-pvc
spec:
    storageClassName: px-csi-db
    accessModes:
        - ReadWriteOnce
    resources:
        requests:
            storage: 2Gi

Run the oc apply command to create a PVC:

oc apply -f <your-pvc-name>.yaml

persistentvolumeclaim/example-pvc created

Verify your StorageClass and PVC

Enter the following oc get storageclass command, specify the name of the StorageClass you created in the steps above:

oc get storageclass <your-storageclass-name>

NAME                   PROVISIONER        RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
example-storageclass   pxd.portworx.com   Delete          Immediate           false                  24m

oc will return details about your storageClass if it was created correctly. Verify the configuration details appear as you intended.

Enter the oc get pvc command, if this is the only StorageClass and PVC you’ve created, you should see only one entry in the output:

oc get pvc <your-pvc-name>

NAME          STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS           AGE
example-pvc   Bound    pvc-dce346e8-ff02-4dfb-935c-2377767c8ce0   2Gi        RWO            example-storageclass   3m7s

oc will return details about your PVC if it was created correctly. Verify the configuration details appear as you intended.
