Kubernetes Upgrade

Use the Kubernetes tab to manage Kubernetes versions. The tab displays a list of nodes, Kubernetes versions, and whether an upgrade is needed. All nodes must be running the same Kubernetes version.

You can upgrade Kubernetes while working either online or offline:

• For online upgrades—The updated Kubernetes version gets downloaded from Docker Hub automatically when you upgrade.
• For offline upgrades—You must upload a Kubernetes package manually before you complete the upgrade.

Before You Begin

When the status message indicates that you need to upgrade Kubernetes, before you upgrade, go to Dashboard > Deployment Health and verify the following:

• Verify the system is in a healthy state.
• Verify all nodes are on the same version of software.
• Verify Deployment Health has all Operational indicators as (Green) NTP is reachable, Kubernetes nodes are healthy, Kubernetes HA cluster is healthy, Load-balancing services are properly configured and accessible.

To upgrade Kubernetes:

1. Go to Administration > System > Software Upgrade.
2. Select the Kubernetes tab.
3. Complete the upgrade using an online or offline upgrade method:
   • For online upgrades—Select UPGRADE and then select OK to begin the upgrade.
   • For offline upgrades—Upload a Kubernetes resource package manually, using either of these methods:
     • Select (Upload Kubernetes resource package zip file) and then browse to the image file and select it.
     • Select the image file from your desktop and drag it into the Upload Kubernetes resource package zip file area on Universal Compute Platform.
     The upgrade begins automatically after the image upload completes.
