Google Cloud Marketplace
This document provides instructions for installing Portworx with Google Kubernetes Engine (GKE)from Google Cloud Marketplace.
Prerequisites
Before installing Portworx Enterprise, ensure that you meet the following prerequisites:
- Environment requirements:
- Image type: Only GKE clusters provisioned on Ubuntu Node Images support Portworx. You must specify the Ubuntu node image when you create clusters.
- Resource requirements:
- A GCP GKE cluster that meets the prerequisites.
- Machine type: n1-standard-4 (4 vCPUs and 4 GB memory)
- For production environments, Portworx recommends 3 Availability Zones (AZs) with one node per zone
- Portworx recommends creating a zonal cluster. For instructions on creating a cluster, refer to the GCP documentation.
- Permissions: Portworx requires access to the Google Cloud APIs to provision & manage disks. Make sure that the user or service account creating the GKE cluster has the following roles:
- Compute Admin
- Service Account User
- Kubernetes Engine Cluster Viewer
Install Portworx
Navigate to the GCP Marketplace
Use the search bar at the top of the Marketplace console to search for Portworx. A list of all Portworx offerings will appear. Select your desired offering.
From the selected offering catalog, click CONFIGURE.
On the Deploy Portworx Enterprise page, change the Namespace field value from default to portworx by selecting portworx from the dropdown menu. Note that
portworxshould be an existing namespace in your environment.noteDo not deploy Portworx in the
defaultnamespace as it may cause failures.Specify your cluster details and click DEPLOY to install Portworx.
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 kubectl get pods command to list and filter the results for Portworx pods:
kubectl get pods -n <px-namespace> -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 kubectl exec command, specifying the pod name you retrieved in the previous section:
kubectl exec <pod-name> -n <px-namespace> -- /opt/pwx/bin/pxctl status

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-dbdefault StorageClass and save the file:kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: px-check-pvc
spec:
storageClassName: px-csi-db
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2GiRun the
kubectl applycommand to create a PVC:kubectl apply -f <your-pvc-name>.yamlpersistentvolumeclaim/example-pvc created
Verify your StorageClass and PVC

kubectl get storageclasscommand:kubectl get storageclassNAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
