Amazon EKS with Terraform
In this section, we will create a managed K8s cluster in AWS so that we can use it in a real-time scenario to bootstrap ready-to-use K8s clusters in production environments. We will describe Amazon EKS, which is the managed K8s cluster of AWS, and how we can provision it with IaC and, more specifically, with Terraform.
Getting familiar with Amazon EKS
Most of the cloud providers have implemented managed K8s and they offer a fully managed control plane. AWS has Amazon EKS, which provides a fully managed and highly available control plane (K8s API server nodes and an etcd cluster).
Amazon EKS helps us to operate and maintain K8s clusters in AWS without a hassle. The API server, scheduler, and kube-controller-manager run in a VPC (https://aws.github.io/aws-eks-best-practices/reliability/docs/controlplane/#eks-architecture) managed by AWS in an auto-scaling group and different Availability Zones in an AWS Region. The following architecture diagram gives...
