Introduction to External DNS in Kubernetes

In this tutorial, i will Introduce to External DNS in Kubernetes and how to automatically create DNS records in Kubernetes using External DNS

Are you running your workloads in GKE / EKS / AKS? Do you use Services of type LoadBalancer? If yes then this is the right article for you. Let us suppose you have a web application running in your Kubernetes Cluster. You might have a public-facing load balancer so that your application is accessible to the entire world. Imagine you have a domain name called kubernetesisgreat.com and you want to map that to your public-facing load balancer provisioned by Kubernetes. For this, you can either use a gcloud command or maybe do it manually. Now, what if you have hundreds of projects and thousands of DNS records to be created? What if the LoadBalancer Endpoint changes? How do you keep a track of hundreds of thousands of DNS records? Here come external-dns to the picture. ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way. ExternalDNS synchronizes exposed Kubernetes Services and Ingresses with DNS providers. ExternalDNS supports multiple DNS providers. A few of them are

1. Google Cloud DNS
2. AWS Route53
3. Azure DNS
4. Digital Ocean, etc.
