Azure Kubernetes Service: Kubernetes 1.9 end-of-life notice
Published date: April 26, 2019
On April 24, 2019, Azure Kubernetes Service (AKS) released Kubernetes 1.13 support in general availability (GA). According to our policy for supported versions, this means that Kubernetes 1.9 support is reaching end of life.
Customers running 1.9 clusters now have 30 days (May 25, 2019) to upgrade to a supported Kubernetes version (1.10, 1.11, 1.12, or 1.13). During this deprecation period, you can continue to create new 1.9.x clusters. But on May 25, 2019, 1.9.x will be removed from the portal and CLI/APIs.
After May 25, 2019, version 1.9 will not be supported. When opening new Azure support requests, users running 1.9 clusters will be asked to upgrade to a supported version.
