AWS DevOps Agent for EKS: Automating Incident Response with Kubernetes Operator

Amazon Elastic Kubernetes Service (EKS) environments often experience pod failures due to OOMKilled or IP exhaustion. Engineers spend time troubleshooting, including collecting pod logs, analyzing Kubernetes events, and checking node system logs. To address this issue, AI-based tools like K8sGPT and Amazon Bedrock Agent have been used. However, these tools have limitations, such as not providing end-to-end automated investigation processes. To overcome these limitations, AWS introduced the AWS DevOps Agent, which connects various sources like code repositories, observability tools, and CI/CD pipelines to analyze the root cause of incidents. The DevOps Agent Operator is a Kubernetes Operator that automatically detects EKS cluster pod failures and triggers the DevOps Agent investigation. This article explains how to build an automated incident response pipeline using the DevOps Agent Operator.
