Kubernetes Version Upgrade Distributed Cloud Orchestration Overview

For an orchestrated Kubernetes version upgrade across a , you need to first create a Kubernetes Version Upgrade Distributed Cloud Orchestration Strategy, or plan, for the automated Kubernetes version upgrade procedure orchestrated across all subclouds of the Distributed Cloud system.

You must use the dcmanager CLI tool to create, and then apply the upgrade strategy. A created strategy can be monitored with the show command. For more information, see Kubernetes Version Upgrade Distributed Cloud Orchestration Procedure <configuring-kubernetes-update-orchestration-on-distributed-cloud>.

Kubernetes upgrade orchestration automatically iterates through all managed online subclouds.

The specific steps involved in a Kubernetes Version Upgrade Distributed Cloud Orchestration for a single or group of hosts in each subcloud includes:

  1. Create the subcloud kube upgrade strategy based on the new version installed as part of the platform.
  2. Apply the subcloud kube upgrade strategy.
