Install Portworx on-prem using the Operator

This topic provides instructions for installing Portworx with Kubernetes on-prem using the Operator.

Install

Airgapped clusters: If your nodes are airgapped and don’t have access to common internet registries, first follow Airgapped clusters to fetch Portworx images.

Install the Operator

Enter the following kubectl create command to deploy the Operator:
```
kubectl create -f https://install.portworx.com/?comp=pxoperator
```

Generate the specs

To install Portworx with Kubernetes, you must generate Kubernetes manifests that you will deploy in your cluster.

Navigate to PX-Central and log in, or create an account, then follow the process to generate a spec.

NOTE: If you’re using a cloud provider and you use the Customize option when generating your spec, do not add volumes of different types when configuring storage devices during spec generation. For example, do not add both GP2 and GP3 for AWS, standard and ssd for GCP, or Standard and Premium for Azure. This can cause performance issues and errors.

Deploy the Operator

To deploy the Operator, run the command that PX-Central provided, which looks similar to the following:

kubectl apply -f 'https://install.portworx.com/<portworx_version>?comp=pxoperator&kbver=<k8s-version>&ns=portworx'

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

To deploy the StorageCluster, run the command that PX-Central provided, which looks similar to the following:

kubectl apply -f “https://install.portworx.com/<portworx_version>?operator=true&mc=false&kbver=1.25.0&ns=portworx&b=true&kd=type%3Dgp3%2Csize%3D150&s=%22type%3Dgp3%2Csize%3D150%22&c=px-cluster-0584f7f1-b6be-4608-800c-2ac5fb8069e0&stork=true&csi=true&mon=true&tel=false&st=k8s&promop=true'

Apply the specs

Apply the generated specs to your cluster.

kubectl apply -f px-spec.yaml

Monitor the Portworx nodes

Enter the following kubectl get command and wait until all Portworx nodes show as ready in the output:
```
kubectl -n kube-system get storagenodes -l name=portworx
```

Enter the following kubectl describe command with the name of one of the Portworx nodes to show the current installation status for individual nodes:

kubectl -n kube-system describe storagenode <portworx-node-name>
