Important Service Updates

  • AKS has updated supported versions as announced in this service update and AKS issue to move from the "N-3" to "N-2" window. Starting December 9th, 2019 AKS has removed support for anything older than K8s 1.13 and scoped the active support window to K8s 1.13, 1.14, and 1.15.
  • K8s 1.16 introduces API deprecations which will impact user workloads as described in this AKS issue. When AKS supports this version user action is required to remove dependencies on the deprecated APIs to avoid disruption to workloads. Ensure you have taken this action prior to upgrading to K8s 1.16 when it is available in AKS.
