Upgrade PX-Central on-premises

If you’ve installed PX-Central using Helm, you can use Helm to upgrade it as well.

Prerequisites

You must have PX-Central with a Helm-based install.

Upgrade

Follow the steps in this section to upgrade PX-Central using Helm.

1. Update your Helm repos:

   helm repo update

2. Retrieve all custom values you used during install. Enter the following helm get values command to generate a YAML file, adjusting the values of the <namespace> and <release-name> parameters to match your environment:

   helm get values --namespace <docs-namespace> <release-name> -o yaml > values.yaml

   oidc:
       centralOIDC:
           defaultPassword: examplePassword
           defaultUsername: exampleUser
   operatorToChartUpgrade: true
   persistentStorage:
       enabled: true
       storageClassName: px-sc
   pxbackup:
       orgName: exampleOrg
   pxcentralDBPassword: exampleDbPassword
   

   Note the following about this example output:

   • The persistentStorage.storageClassName field displays the name of your storage class (px-sc).
   • The persistentStorage.enabled: true field indicates that persistent storage is enabled.
   • The pxbackup.orgName field displays the name of your organization (my-organization)

3. Delete the post install hook job:

   kubectl delete job pxcentral-post-install-hook --namespace <namespace>

4. Run the helm upgrade command, using the -f flag to pass the custom values.yaml file you generated above and replacing <namespace> with your namespace:

   helm upgrade px-backup portworx/px-backup --namespace <namespace>  -f values.yaml
