Deprecation Notice

Bottlerocket 1.0.8 is the last release where we plan to support the Kubernetes 1.15 variant, aws-k8s-1.15. Kubernetes 1.15 is no longer receiving support upstream. We recommend replacing aws-k8s-1.15 nodes with a later variant, preferably aws-k8s-1.19 if your cluster supports it. See this issue for more details.
