Building a Production-Ready Kubernetes Cluster on AWS EKS

A comprehensive guide to setting up a production-grade Kubernetes cluster on Amazon EKS. Learn how to integrate essential components like Karpenter for efficient node provisioning, Istio for service mesh, ArgoCD for GitOps deployments, AWS Load Balancer Controller for external access, and EFS CSI Driver for persistent storage.

BotKube

In this comprehensive guide, we’ll walk through setting up a production-ready Kubernetes cluster on Amazon EKS (Elastic Kubernetes Service). We’ll explore each component and understand why they’re essential for a robust, scalable, and maintainable infrastructure.

Effortless EKS Monitoring with ChatOps using Botkube

ChatOps allows us to operate DevOps tools using chat clients. Implementing ChatOps with EKS is painless using BotKube. This tool lets us monitor and debug our K8S cluster. The app integrates with Slack, Teams, etc. So, for example, we could view our K8S deployments with a simple command on Slack or view logs in real-time. Also, give us recommendations for standard practice, such avoid using the latest containers image versions.

BotKube

This updated version revisits a blog post I authored two years ago, during which time Botkube has incorporated additional features and undergone changes to its installation process. Also, this post show how to do it with AWS EKS, but is similar for any K8S flavor.

AWS Ingress controller integration with External DNS and ACM on EKS

Integrating the AWS Ingress controller with External DNS and ACM streamlines the exposure of multiple applications via a single Application Load Balancer (ALB), offering a cost-effective solution by consolidating resources. This approach not only automates DNS record creation with ExternalDNS and Route53, directly within Kubernetes for enhanced efficiency but also ensures secure connections through SSL termination with AWS Certificate Manager (ACM). This cost-saving integration facilitates seamless and secure access to services on EKS clusters, showcasing the efficiency and financial advantages of leveraging these combined technologies for optimal application management.

Ingress

This POC demonstrates the integration of Amazon EKS with the Application Load Balancer (ALB) Ingress Controller. The primary goal is to expose multiple applications through a single ALB efficiently. This setup utilizes ExternalDNS in conjunction with Route53 to dynamically create DNS records using Ingress annotations within Kubernetes.
