Please upgrade all Kubernetes 1.10.x clusters to a supported version (1.11, 1.12, 1.13, or 1.14) by October 25, 2019.
Azure Kubernetes Service (AKS) released support for Kubernetes 1.14 on August 5, 2019. Because we support three previous minor versions, per our Kubernetes version support policy, support for Kubernetes 1.10.x clusters will end on October 25, 2019. You will still be able to create new 1.10.x clusters until that date, however, 1.10.x will be removed from the Azure portal, CLI, and APIs at that time.
After October 25, 2019, you’ll be asked to upgrade to a supported version when you open new Azure support requests.
If you have questions, please contact us.
