Azure Kubernetes Service upgrade

Azure Kubernetes Service (AKS) cluster requires regular updates to the Kubernetes versions. Using the latest AKS version supported by Cloudera avoids compatibility issues between Cloudera Data Warehouse (CDW) and Azure resources.

Using the Azure CLI or Azure portal to upgrade the AKS cluster is not supported. CDW automatically provisions the latest supported AKS version when you activate an environment in CDW. AKS 1.29 is provisioned automatically when you activate your environment from CDW using release 1.9.1-b233 (released July 26, 2024) and onwards.

To upgrade to the latest AKS, you must deactivate and reactivate your CDW environment. To restore the state of your CDW cluster after reactivation, Cloudera recommends using the backup-restore functionality. For more information, see Backing up and restoring CDW.
