Announcing Node Health Monitoring and Auto-Repair for Amazon EKS

Amazon Elastic Kubernetes Service (Amazon EKS) now monitors the health of the EC2 instances (nodes) in EKS clusters for Kubernetes-specific health issues and automatically takes action to repair them if they become unhealthy. This helps you achieve higher availability for your Kubernetes applications and reduces the operational overhead required to keep cluster infrastructure performing optimally.

Managing the nodes where Kubernetes applications run to ensure they remain resilient to errors can be challenging and operationally intensive. This launch streamlines cluster infrastructure maintenance by continuously monitoring the health of the nodes within an EKS cluster, automatically detecting health issues and replacing nodes with issues when they arise. You can enable this feature’s health monitoring and repair capabilities by installing the new EKS node monitoring agent add-on in new or existing EKS clusters and then enabling node auto-repair in the EKS managed node group APIs or AWS Console. EKS Auto Mode comes with both the node monitoring agent and node auto-repair enabled.

EKS node health monitoring and auto-repair is available today at no additional cost in all AWS Regions, except AWS GovCloud (US) and China Regions.
