Upgrade Portworx on Kubernetes using the Operator

caution

If you're upgrading OpenShift to 4.3, you must change Portworx before you can do so. See the Preparing Portworx to upgrade to OpenShift 4.3 page for details.

If you're using the Portworx Operator, you can upgrade or change your Portworx version at any time by modifying the StorageCluster spec. In addition to managing a Portworx cluster, the Operator also manages the following other components in the Portworx platform:

• Stork
• Autopilot

For simplicity, the Portworx Operator handles the component upgrades without user intervention. When Portworx upgrades, the Operator upgrades the installed components to the recommended version as well.

Prerequisites

• You must already be running Portworx through the Operator, this method will not work for other Portworx deployments.
• You must be running the latest available version of the Operator.

• For an air-gapped environment, complete the instructions in the Get the updated container images section.

Prepare Anthos environments

If you're not running Portworx on Anthos, skip this section.

If your Portworx cluster is managing the underlying storage devices in an Anthos deployment, add the following annotation to the StorageCluster spec to ensure that during an Anthos or a Portworx upgrade, Portworx does not failover the internal KVDB to a storageless node:

portworx.io/misc-args: "-rt_opts wait-before-retry-period-in-secs=360"

Upgrade Portworx

Upgrade Portworx

note

• If using configmap, update the version manifest for Portworx Operator. Otherwise, you might not see the expected image versions.
• If you override the default PodDisruptionBudget in OpenShift platforms, ensure that the storage-pdb-min-available value is greater than or equal to OCP's MCP maxUnavailable.
• If you override the default PodDisruptionBudget in GKE environments, ensure that the maxUnavailable is less than the storage-pdb-min-available value for a balanced speed and disruption. Portworx by Pure Storage recommends using the following configurations for surge upgrades:
  • maxSurge=1
  • maxUnavailable=0

1. Identify Your StorageCluster:

   Retrieve the name of your Portworx storage cluster within the appropriate namespace:

   kubectl get storagecluster -n <px-namespace>

   NAME                                            STATUS   VERSION   AGE
   px-cluster-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx Online   2.10.3    43d

   If your cluster is installed in a different namespace, specify it using the -n flag.

2. Edit the StorageCluster:

   Modify the StorageCluster resource to update Portworx to the desired version:

   kubectl edit storagecluster -n <px-namespace> <storagecluster-name>

   In the editor, change the spec.image field to your desired Portworx version:

   apiVersion: core.libopenstorage.org/v1
   kind: StorageCluster
   metadata:
      name: portworx
      namespace: <px-namespace>
   spec:
      image: portworx/oci-monitor:<desired-version>
   note

   To look up recent versions, refer to the Portworx release notes

3. Verify the Upgrade:

   Confirm the upgrade by checking the Portworx version on the nodes:

   kubectl get storagenodes -n <px-namespace> -l name=portworx

   NAME       ID                                     STATUS   VERSION          AGE
   node-1-1   xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx   Online   <desired-version>   10d

note

For air-gapped clusters, if you do not see the expected image versions that you have configured in the configmap, you should edit the StorageCluster to include the autoUpdateComponents: Once parameter. This will force Portworx Operator to reconcile all the components and retrieve the correct images.
