Azure Kubernetes Service—Retiring support for Kubernetes versions 1.11 and 1.12

Updated: 30 September, 2019

On Monday, 9th December 2019 (09-12-2019), we are removing support for Kubernetes versions older than the latest version (N) and two minor versions prior (N-2), because support for Kubernetes 1.15 will become available on that date. Customers running Kubernetes versions older than Kubernetes 1.13.x must upgrade by Monday, 9th December 2019, to remain in support. After that date, customers will be asked to upgrade to a supported version when they open new Azure support requests. Please note: this date is specific to AKS and is not related to any upstream or community dates for Kubernetes 1.15.

We are making this change now to align more closely with the upstream Kubernetes project and to provide a more consistent experience for customers with regards to bug fixes, security patches and component compatibility.

With this change, AKS will support the current generally available Kubernetes release and the two previous minor versions (N-2). Historically, AKS has supported the current generally available release of Kubernetes, as well as the three prior minor versions (N-3). When a new minor version is released, the oldest minor version is removed.

After Monday, 9th December 2019, the supported Kubernetes minor releases will be:

  • 1.13.x
  • 1.14.x
  • 1.15.x

To verify what versions are available in your region:

```
az aks get-upgrades --resource-group myResourceGroup --name myAKSCluster --output table
```

To upgrade your clusters using the Azure CLI:

```
az aks upgrade --resource-group myResourceGroup --name myAKSCluster --kubernetes-version <NEW VERSION>
```

For additional information, please see the AKS Kubernetes support policy.

If you have questions, please contact us.
