What is Amazon EKS Upgrade Insights?

Upstream Kubernetes releases 2-3 new versions every year. Kubernetes APIs continue to get deprecated and removed in each release. Any application using a removed API risks disruption if it’s not upgraded to supported APIs before Kubernetes upgrade. EKS Upgrade Insights highlights deprecated and removed APIs being used by applications. According to AWS: “Upgrade insights scans cluster’s audit logs for events related to APIs that have been deprecated. These events include information about who initiated it (i.e., the caller) and the Kubernetes resource(s) that it was initiated against. Upgrade Insights presents this information to you in a concise and easily consumable way so you can identify and remediate the appropriate resources before executing the upgrade.” The information can also be retrieved programmatically using the Amazon EKS API or the AWS Command Line Interface (AWS CLI). Insight statuses:
  • Error: Impacted in the next version (N+1).
  • Warning: Impacted in a future version (N+2 or more).
  • Passing: No issues detected.
  • Unknown: Unable to determine impact.

How does Chkk Upgrade Copilot use Amazon EKS Upgrade Insights?

For EKS customers, Chkk uses EKS Upgrade Insights to detect Kubernetes APIs that have been deprecated and can cause application failures. Chkk also uses EKS Insights about version skew between control plane and kubelet versions in it’s Upgrade Plans. While API deprecations/removals and version skew are critical to identify and address before an upgrade, there are many other dependencies, incompatibilities, and safety/availability risks across layers of infrastructure (cloud substrate, control plane, nodes, add-ons, application services, Kubernetes operators, and applications) that must be addressed to derisk upgrades. For reference, a typical cluster Upgrade Plan from Chkk comprises 80+ steps. API deprecations/removals and version skew are only relevant for a handful of these steps.
