Kubernetes 1.21 went out of upstream support in June, 2021. AWS EKS is maintaining support for 1.21 until February 15th, 2023. Bottlerocket will end support of our K8s 1.21 variants at that time.
While you’ll still be able to launch *-k8s-1.21 nodes beyond February 15th, 2023, we’ll no longer provide updated *-k8s-1.21 images, and the Bottlerocket repositories will no longer receive new updates for nodes running K8s 1.21 variants.
We recommend you replace existing Bottlerocket K8s 1.21 nodes with a newer variant - ideally the latest your Kubernetes cluster supports.
For instructions on how to migrate your aws-k8s-1.21 nodes to newer supported versions, please consult the EKS documentation for updating clusters or reach out to us through your AWS support channels for additional questions.
