Questions tagged [amazon-eks]

Amazon Elastic Kubernetes Service (EKS) is a part of Amazon Web Services (AWS) and provides a fully managed Kubernetes platform, with the ability to have your containers deployed across a EC2 backed solution or as a serverless solution with AWS Fargate. Use this tag for programming-related questions specific to the EKS environment.

Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service.

In most cases EKS acts like a standard Kubernetes installation, and questions labeled with will frequently also be tagged . You do not need if you can easily reproduce your issue in a local Kubernetes environment like Docker Desktop or Minikube but in production you happen to be using EKS.

Remember that Stack Overflow questions must specifically be programming-related. Questions about setting up EKS clusters, configuring IAM roles, and other cluster-level configuration are off-topic for Stack Overflow. Depending on the specific question another Stack Exchange site like Server Fault or DevOps.SE may be a better place to ask.
