Portworx Operator Add-on

Versions Supported​

The default installation of Portworx /w Operator will deploy the following components in the Kubernetes cluster:

  • Portworx Operator

  • StorageCluster resource that tells the Operator how to deploy and configure Portworx.

  • StorageClass resource for dynamic provisioning of PersistentVolumes`` using the pxd.portworx.com` provisioner.

  • Stork. Portworx's storage scheduler for Kubernetes.


License Model​

This pack can install Portworx in three different licensing modes:

  • Essentials: a free Portworx license with limited functionality that allows you to deploy a small production or proof-of-concept workloads. Essentials limits capacity and advanced features, but otherwise functions the same way as the fully featured Portworx Enterprise version of Portworx.

  • Enterprise: the fully featured version of Portworx. If you install this model without a valid key, Portworx will automatically enter a 30-day trial mode.

  • Enterprise SaaS PAYG: the fully featured version of Portworx but using a SaaS license key that allows unlimited use and in-arrears billing. If you install this model without a valid key, Portworx will automatically enter a 30-day trial mode.

Use the presets in the pack user interface to select which license model you want to use, then update the charts.portworx-generic.license section for your chosen license model.


license:
  type: essentials
  essentials:
    # Base64-decoded value of the px-essen-user-id value in the px-essential secret
    # Find your Essentials Entitlement ID at https://central.portworx.com/profile
    userId: 1234abcd-12ab-12ab-12ab-123456abcdef
    # Base64-decoded value of the px-osb-endpoint value in the px-essential secret
    # Leave at the default value unless there are special circumstances
    endpoint: https://pxessentials.portworx.com/osb/billing/v1/register

Storage Specification​

You can install Portworx in a variety of storage configurations.

  • Existing disks (generic): This mode does not integrate with any particular storage solution, it uses existing disks available on the nodes.

  • AWS Cloud Storage: This mode integrates with Amazon EBS block volumes and allows AWS EKS and EC2 based Kubernetes clusters to dynamically attach EBS volumes to worker nodes for Portworx.

  • Azure Cloud Storage: This mode integrates with Azure block storage and allows Azure AKS and regular Azure Kubernetes clusters to dynamically attach Azure block storage to worker nodes for Portworx.

  • Google Cloud Storage: This mode integrates with Google persistent disks and allows GKE and regular Google Kubernetes clusters to dynamically attach persistent disks to worker nodes for Portworx.

  • VMware vSphere Datastores: This mode integrates with VMware vSphere storage and allows Kubernetes clusters on vSphere to dynamically attach vSAN and regular Datastore disks to worker nodes for Portworx.

  • Pure Storage Flash Array: This mode integrates with Pure Storage Flash Arrays and allows Kubernetes clusters to dynamically attach Flash Array disks over iSCSI to worker nodes for Portworx.

tip

Use the presets in the pack user interface to select which storage specification you want to use, then update the charts.portworx-generic.storageCluster section to your specific needs.

Select the tab below for the storage specification you want to use. Use the example YAML as a starting point for your configuration.


storageCluster:
  spec:
    # Use the Portworx Spec Builder at https://central.portworx.com/landing/login to define custom configurations, then paste the spec section here

Etcd​

Portworx Enterprise supports multiple etcd scenarios. Portworx will default to an internal key-value store (KVDB).

Kvdb and Etcd Presets​

The following pack presets are available for configuring etcd.

The pack defaults to the Use Internal Kvdb option. You can change to a different preset if you need to connect to an external etcd server.

storageCluster:
  spec:
    kvdb:
      internal: true

Integration With External Etcd​

Use the following steps to integrate Portworx to an external etcd server by following the steps below.

  1. During the cluster profile creation, select the Portworx pack and click on the Presets button in the top right corner of the pack user interface.

  2. Select the Use External Kvdb over HTTP or Use External Kvdb over SSL preset in the pack UI. If your external etcd server requires certificate authentication, select Use External Kvdb over SSL preset.

  3. Configure the external etcd endpoints in the YAML parameter block named charts.portworx-generic.storageCluster.spec.kvdb.endpoints.

  4. If you selected the Use External Kvdb over SSL preset, you will also need to configure the charts.portworx-generic.externalKvdb section. Set charts.portworx-generic.externalKvdb.useCertsForSSL to true to enable certificate authentication. Input your SSL certificates in the cacert, cert, and key sections of charts.portworx-generic.externalKvdb. The preset will give you cropped example values that you can overwrite with your actual PEM certificates. Leave the charts.portworx-generic.storageCluster.spec.kvdb.endpoints option to its default of px-kvdb-auth. The name of the Kubernetes secret will automatically get created by this pack.

warning

When inserting SSL certificate values into the YAML. Ensure you follow the provided indentation style. Otherwise, SSL certificates will not be imported correctly and will result in Portworx deployment failure.


Terraform​

Use the following Terraform code to interact with the Portworx Operator pack in your Terraform scripts.

data "spectrocloud_registry" "public_registry" {
  name = "Public Repo"
}

data "spectrocloud_pack_simple" "portworx-operator" {
  name    = "csi-portworx-add-on"
  version = "3.0.0"
  type = "operator-instance"
  registry_uid = data.spectrocloud_registry.public_registry.id
}
