Install Portworx on Anthos bare metal or VMware cluster using the spec generator

This guide provides instructions for installing Portworx on Anthos.

Prerequisites

  • Anthos cluster
  • Your cluster must meet the requirements for installing a Portworx cluster.

Install Portworx on an Anthos cluster

Perform the following steps to install Portworx.

Get your Kubernetes version

Run this command to get the Kubernetes version installed on your cluster for use in the later section:

(kubectl version --short 2>&1 || kubectl version) | awk -Fv '/Server Version: / {print $3}'

Generate the specs

  1. Navigate to Portworx Central and login, or create an account.

  2. Select the Get Started button

  3. In the Product Line page -> Portworx Enterprise section, select Continue.

  4. In the Generate Spec page -> Step 1: Select Your Platform section -> Platform dropdown menu, you can select Google Cloud from the CLOUD section or vSphere or Pure FlashArray from the ON-PREMISES section.

    • If you select vSphere, then specify the vCenter endpoint and datastore prefix.
  5. In the Step 2: Select Kubernetes Distribution section -> Distribution Name dropdown menu, select Anthos as your distribution:

  6. Enter other relevant details, such as Cluster Selector Label and Namespace.

    • Cluster Selector Label: By assigning this label to a cluster, you can specify that certain configurations or software installations should only be applied to clusters that match the label criteria. For example, when installing Portworx on an Anthos cluster, you might want to target only those clusters that are designated for storage-intensive applications. To achieve this, you can use the Cluster Selector Label to mark these specific clusters. For instance, label your target cluster with a specific selector:

      metadata:
      labels:
      configmanagement.gke.io/cluster-selector: storage-intensive

      In your Portworx installation configuration, specify that it should only be applied to clusters with the storage-intensive label. This ensures that Portworx is only installed on clusters designated for storage-heavy workloads, optimizing resource usage and deployment strategies across your Anthos environment.

  7. In the Step 3: Summary section -> K8S Version field, enter the complete Kubernetes version string that you retrieved in the previous section. Also, you can modify the cluster name prefix if required.

  8. Select Save Spec to generate the specs.

    note

    Review all default configurations in the Summary section. Select Customize and proceed to the subsequent pages if you need to modify any storage and network related configurations. After modifying the configurations, you can select Finish to generate the spec.

Apply the specs

Apply the Portworx Operator and StorageCluster specs you generated in the section above using the following steps:

  1. Run the following wget command by replacing the <cluster-name> with your cluster name:

    wget -O portworx-anthos-storage-intensive-2024-02-13-05-04-27.zip 'https://install.portworx.com/3.1?operator=true&mc=false&kbver=1.25.0&ns=portworx&b=true&iop=6&s=%22size%3D150%22&pureSanType=ISCSI&c=px-cluster-<cluster-name>&acr=storage-intensive&ctl=true&stork=true&csi=true&mon=true&tel=true&st=k8s&promop=true'
  2. Extract the .zip file in the wget command:

    unzip portworx-anthos-storage-intensive-2024-02-13-05-04-27.zip

    You will get the px-operator and storage-cluster YAML files.

  3. Run the following command to deploy the Portworx Operator:

    kubectl create -f px-operator-portworx-local-px-int-2024-02-21-09-42-55.yaml
    serviceaccount/portworx-operator created
    clusterrole.rbac.authorization.k8s.io/portworx-operator created
    clusterrolebinding.rbac.authorization.k8s.io/portworx-operator created
    deployment.apps/portworx-operator created
  4. Run the following command to deploy the StorageCluster:

    kubectl create -f storage-cluster-<px-namespace>-local-px-int-2024-02-21-09-42-55.yaml
    storagecluster.core.libopenstorage.org/px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-f50775cb041b created

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:

  1. 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
  2. Run the kubectl apply command to create a PVC:

    kubectl apply -f <your-pvc-name>.yaml
    persistentvolumeclaim/px-check-pvc created

Verify your StorageClass and PVC

  1. Enter the kubectl get storageclass command:

    kubectl get storageclass
    NAME                                 PROVISIONER                     RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE

    px-csi-db-cloud-snapshot-encrypted pxd.portworx.com Delete Immediate true 43d
    px-csi-db-encrypted pxd.portworx.com Delete Immediate true 43d
    px-csi-db-local-snapshot pxd.portworx.com Delete Immediate true 43d

    px-db-cloud-snapshot kubernetes.io/portworx-volume Delete Immediate true 43d
    px-db-cloud-snapshot-encrypted kubernetes.io/portworx-volume Delete Immediate true 43d
    px-db-encrypted kubernetes.io/portworx-volume Delete Immediate true 43d
    px-db-local-snapshot kubernetes.io/portworx-volume Delete Immediate true 43d
    px-db-local-snapshot-encrypted kubernetes.io/portworx-volume Delete Immediate true 43d
    px-replicated kubernetes.io/portworx-volume Delete Immediate true 43d
    px-replicated-encrypted kubernetes.io/portworx-volume Delete Immediate true 43d
    stork-snapshot-sc stork-snapshot Delete Immediate true 43d

    kubectl returns details about the StorageClasses available to you. Verify that px-csi-db appears in the list.

  2. Enter the kubectl get pvc command. If this is the only StorageClass and PVC that you've created, you should see only one entry in the output:

    kubectl get pvc <your-pvc-name>
    NAME          STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS           AGE
    px-check-pvc Bound pvc-xxxxxxxx-xxxx-xxxx-xxxx-2377767c8ce0 2Gi RWO example-storageclass 3m7s

    kubectl returns details about your PVC if it was created correctly. Verify that the configuration details appear as you intended.
