AWS recently announced their roadmap to updating managed EKS clusters. Overall it’s solid, and will be a great way to keep up with GKE. We recently upgraded our clusters from 1.14 to 1.15, and the process was very straightforward. Amazon’s documentation is clear about the DNS, CNI, kube-proxy, and other kube-system components that need to be upgraded before the masters.
Our Helm charts and manifests are up-to-date with current API versions, so upgrading to 1.16 should be a quiet affair. Overall we’re enjoying the hosted EKS, and will report back on future cluster upgrades
