Auto Scale DNS using kubernetes and CI/CD deployment using gitlab
Imagine that your application can automatically add another container to serve more request and delete unused container when requests are declining, with this approach, you can preserve the resources for another application and also decrease the bill for cloud resource usage. With kubernetes, you can achieve this using HPA (Horizontal pod autoscaler) or using vertical autoscaler. But in this tutorial, we will only show how to use HPA. The case for this tutorial is to autoscale DNS to serve approximately thousand users. We need external Load Balancer to forward requests to kubernetes.
