Install Portworx on bare metal Kubernetes
This article provides instructions for installing Portworx on bare metal Kubernetes clusters using the Portworx Operator.
Prerequisites
- You must have a Kubernetes cluster deployed on infrastructure that meets the minimum requirements for Portworx.
- You must attach the backing storage disks to each worker node.
- You must have dedicated disk for internal kvdb.
- The KVDB device given above needs to be present only on 3 of your nodes and it should have a unique device name across all the KVDB nodes.
Install Portworx
Generate specs
To install Portworx with Kubernetes, you must first generate Kubernetes manifests that you will deploy in your cluster:
-
Navigate to Portworx Central and log in, or create an account.
-
Select Portworx Enterprise from the product catalog.
-
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, select DAS/SAN. Select None for Distribution Name, then click Save Spec to generate the specs.
Apply specs
Apply the Operator and StorageCluster specs you generated in the section above using the kubectl apply command:
-
Deploy the Operator:
kubectl apply -f 'https://install.portworx.com/<version-number>?comp=pxoperator'serviceaccount/portworx-operator created
podsecuritypolicy.policy/px-operator created
clusterrole.rbac.authorization.k8s.io/portworx-operator created
clusterrolebinding.rbac.authorization.k8s.io/portworx-operator created
deployment.apps/portworx-operator created -
Deploy the StorageCluster:
kubectl apply -f 'https://install.portworx.com/<version-number>?operator=true&mc=false&kbver=&b=true&c=px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-8dfd338e915b&stork=true&csi=true&mon=true&tel=false&st=k8s&promop=true'storagecluster.core.libopenstorage.org/px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-8dfd338e915b created
Monitor Portworx nodes
-
Enter the following
kubectl getcommand and wait until all Portworx nodes show asReadyorOnlinein the output:kubectl -n <px-namespace> get storagenodes -l name=portworxNAME ID STATUS VERSION AGE

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: 2Gi -
Run the
kubectl applycommand to create a PVC:kubectl apply -f <your-pvc-name>.yamlpersistentvolumeclaim/px-check-pvc created
Verify your StorageClass and PVC
-
Enter the
kubectl get storageclasscommand:kubectl get storageclassNAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
