Upgrade your AKS cluster to a supported Kubernetes version You're receiving this notice because you currently use Azure Kubernetes Service (AKS). AKS is retiring v1.21.x on 31 July 2022. We've detected that one or more AKS clusters in your subscription(s) are using Kubernetes v1.21.x or lower. To stay within supported versions and service-level agreements (SLA) you have up to 30 days after the version is removed to upgrade. To avoid ever falling out of support and to keep up with Kubernetes versions, we recommend turning on auto-upgrade. Recommended action Please upgrade your clusters to 1.22.x or higher by 31 July 2022. More information To keep up to date with all AKS releases, subscribe to the AKS Releases page. To know when the next versions will be introduced or retired, check the Kubernetes release calendar for AKS. If you have questions, get answers from community experts in Microsoft Q&A. If you have a support plan and you need technical help, please contact us.
