## Create EKS cluster
eksctl create cluster --name multiappelb --node-type t2.large --nodes 1 --nodes-min 1 --nodes-max 2 --region us-east-1 --zones=us-east-1a,us-east-1b,us-east-1c

## Get EKS Cluster service
eksctl get cluster --name multiappelb --region us-east-1

## Update Kubeconfig 
aws eks update-kubeconfig --name multiappelb

## Get EKS Pod data.
kubectl get pods --all-namespaces

## Delete EKS cluster
eksctl delete cluster --name multiappelb --region us-east-1

##################### Commands to follows #####################################################################################
## AWS CLI to create repository.
aws ecr create-repository --repository-name green
aws ecr create-repository --repository-name yellow

## Get variables required next run.
$AWS_REGION="us-east-1"
$AWS_REGISTRY_ID="357171621133"
$AWS_ECR_REPO="357171621133.dkr.ecr.us-east-1.amazonaws.com"

## Authenticate your docker to ecr == > gives encrypted password for docker
aws ecr get-login-password --region us-east-1

## Final Authenticate to ecr
aws ecr --region us-east-1 | docker login -u AWS -p <Above encrytped password> 357171621133.dkr.ecr.us-east-1.amazonaws.com/yellow
aws ecr --region us-east-1 | docker login -u AWS -p <Above encrytped password> 357171621133.dkr.ecr.us-east-1.amazonaws.com/green

## Build , Tag and Push the image yellow
cd yellow/
docker build . -t yellow
docker tag yellow:latest 357171621133.dkr.ecr.us-east-1.amazonaws.com/yellow:latest
docker push 357171621133.dkr.ecr.us-east-1.amazonaws.com/yellow:latest

## Pre-requisite links
https://docs.aws.amazon.com/eks/latest/userguide/getting-started-eksctl.html

## Have Helm installed in your VM
helm version --short

## What Kubernetes Ingress
"Kubernetes Ingress is an API object that provides routing rules to manage external user`s access to the services in a Kubernetes cluster,
typically via HTTPS/HTTP"

## Get EKS Cluster service
eksctl get cluster --name multiappelb --region us-east-1

## Create IAM OIDC provider
eksctl utils associate-iam-oidc-provider --region us-east-1 --cluster multiappelb --approve

## Create an IAM policy called
aws iam create-policy --policy-name AWSLoadBalancerControllerIAMPolicy --policy-document file://iam_policy.json

## Create a IAM role and ServiceAccount
eksctl create iamserviceaccount --cluster multiappelb --namespace kube-system --name aws-load-balancer-controller --attach-policy-arn arn:aws:iam::357171621133:policy/AWSLoadBalancerControllerIAMPolicy --override-existing-serviceaccounts --approve

## Install the TargetGroupBinding CRDs
kubectl apply -k github.com/aws/eks-charts/stable/aws-load-balancer-controller/crds?ref=master
kubectl get crd

## Deploy the Helm chart
helm repo add eks https://aws.github.io/eks-charts

## Configure AWS ALB (Apllication Load Balancer) to sit infront of Ingress
helm upgrade -i aws-load-balancer-controller eks/aws-load-balancer-controller -n kube-system --set clusterName=multiappelb --set serviceAccount.create=false --set serviceAccount.name=aws-load-balancer-controller

kubectl -n kube-system rollout status deployment aws-load-balancer-controller

## Deploy Sample Application
kubectl apply -f .\color-app.yaml

## Verify Ingress
kubectl get ingress/color-app-ingress -n color-app

## Get Ingress URL
kubectl get ingress/color-app-ingress -n color-app -o jsonpath='{.status.loadBalancer.ingress[0].hostname}'

## Get EKS Pod data.
kubectl get pods --all-namespaces

## Delete EKS cluster
eksctl delete cluster --name multiappelb --region us-east-1
