Prerequisites

• Terraform >=v0.12 https://www.terraform.io/downloads.html
• AWS CLI https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html aws configure
• AWS IAM Authenticator https://docs.aws.amazon.com/eks/latest/userguide/install-aws-iam-authenticator.html
• kubectl https://kubernetes.io/docs/tasks/tools/install-kubectl/
• wget (required for the eks module) https://www.gnu.org/software/wget/

1. Fulfil variables.tf file to add your credentials to AWS and change defined names as desired.

Check if all data have being filled

$ terraform init $ terraform plan

Roll it up - It should take about 10 min to be done

$ terraform apply

Configure cluster's credentials

$ terraform output kubeconfig > kubeconfig

Confirm by

$ kubectl config view

At this point you won't see any nodes or pods. To get that, configure configmap of authentication

$ terraform output config-map-aws-auth > aws-auth.yaml && kubectl apply -f aws-auth.yaml

Check until nodes are ready

$ kubectl get nodes -w

Results: EKS Cluster Creating Steps

• Create ServiceRole - Give the master control-place permission to create cluster on behalf of you
• Create VPC - Create subnets to allow a HA network for your worker nodes exposing them via gateway
• Create Cluster - EKS with a HA ETCD and Master Control-Plane
• Provision Worker Nodes - Provision EC2 instances with a configuration file allows them communicate with EKS
• Apply AWS-Auth - Allow your instances to connect with EKS
• Apply app/ data;
