To improve the stability and availability of the CoreDNS Deployment, versions v1.9.3-eksbuild.5 and later and v1.10.1-eksbuild.2 are deployed with a PodDisruptionBudget. If you’ve deployed an existing PodDisruptionBudget, your upgrade to these versions might fail. If the upgrade fails, completing one of the following tasks should resolve the issue:

  • When doing the upgrade of the Amazon EKS add-on, choose to override the existing settings as your conflict resolution option.
  • Remove your existing PodDisruptionBudget and try the upgrade again.
