Production Ready EKS CoreDNS Configuration

October 18, 2023February 26, 2021

As a “Managed Kubernetes” offering, AWS EKS comes with some essential core services, like CoreDNS. (kube-proxy etc.) CoreDNS is an open source DNS service with Kubernetes plugin for service discovery and by default it’s a DNS server for most of the Kubernetes distribution. Service discovery is actually the main motivation behind hosting a DNS server inside the Kubernetes cluster, otherwise all DNS queries would go to external DNS server.

Purpose of each components can be listed as; AWS Web Application Firewall: CloudFront S3 As on this post we won’t look at origin/resource of CloudFront, we can start configuration with CloudFront. Creating S3 Bucket Although it’s not something to learn on this port, as we’ll give reference to this post, it’s nice to put S3 code here as …
