This is an automation of EKS and resource creation in AWS. I've used terraform to init the EKS cluster.

In order to launch the cluster following commands are useful.

This will basicaly plan the infrastructure change that the Terraform is going to apply by using 'apply' command.

terraform init -input=false
terraform plan 

This will actually execute the 'Apply' and create the EKS cluster. It will do all the resource creation that mentioned in previous step.

terraform apply

You need to save the output of the EKS cluster after terraform creates it.

mkdir ~/.kube
terraform output -raw kubeconfig>~/.kube/config

Note: After you create the cluster you need to install kubectl. This config file will be used to connect to the cluster.

You may need to create ingress controller first using helm <install helm and IAM authenticator>

curl -L https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/download/v0.3.0/heptio-authenticator-aws_0.3.0_linux_amd64 -o /usr/local/bin/aws-iam-authenticator && chmod +x /usr/local/bin/aws-iam-authenticator
curl https://get.helm.sh/helm-v3.5.2-linux-amd64.tar.gz | tar xvz && mv linux-amd64/helm /usr/bin/helm && chmod +x /usr/bin/helm

Install ingress controller

helm repo add nginx-stable https://helm.nginx.com/stable
helm repo update
helm install my-release nginx-stable/nginx-ingress

Create the depoyments, services, pods, and ingress using kubectl ( all the YAML available in kubemanifests dir will be applied.

kubectl apply -f ./kubemanifests

Delete the running services, pods, pvc, ingress

kubectl delete -f ./kubemanifests

This will destroy the infrastructure in one go. It will actualy plan the destruction of the resources and on confirmation it will actually remove the resource that has been created using 'apply'.

This will showcase the list of resources that terraform can destroy on destroy command next.

terraform plan -destroy -out tfdestroy

Destroy the infrastructure EKS. It will delete the cluster and remove the resources it created earlier.

terraform destroy
