Kubernetes Version Upgrade Distributed Cloud Orchestration Overview¶
Before you create a Kubernetes Version Upgrade Distributed Cloud Orchestration Strategy, ensure that the Kubernetes version on the System Controller has been upgraded using the procedure documented in Manual Kubernetes Version Upgrade.
For an orchestrated Kubernetes version upgrade across a Distributed Cloud, 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 Create Kubernetes Version Upgrade Cloud Orchestration Strategy.
Kubernetes upgrade orchestration automatically iterates through all managed online subclouds if you do not specify a group of subclouds to be upgraded.
The specific steps involved in a Kubernetes Version Upgrade Distributed Cloud Orchestration for a single or group of hosts in each subcloud includes:
Creating the subcloud kube upgrade strategy based on the new version installed as part of the platform.
Applying the subcloud kube upgrade strategy.
