1. Create EKS cluster.

eksctl create cluster --name <cluster-name> --region <region-code> --fargate

2. Create a fargate profile for the namespace.

eksctl create fargateprofile \
    --cluster <cluster-name> \
    --region <region> \
    --name <name of profile> \
    --namespace <name of the namespace>

3. Deploy using the helm chart.

Use this repo for helm chart.

helm install v0.1.0 ./1-tier-chart

4. Install AWS ALB Controller.

   1. Create an IAM OIDC provider.

   eksctl utils associate-iam-oidc-provider \
   --region <region-code> \
   --cluster <your-cluster-name> \
   --approve
   

   2. Install the IAM Policy.

   curl -o iam-policy.json https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/v2.8.2/docs/install/iam_policy.json 
   

   3. Create the IAM Policy

   aws iam create-policy \
   --policy-name AWSLoadBalancerControllerIAMPolicy \
   --policy-document file://iam-policy.json
   

   4. Create an IAM role and Kubernetes ServiceAccount for the LBC.

   eksctl create iamserviceaccount \
   --cluster=<cluster-name> \
   --namespace=kube-system \
   --name=aws-load-balancer-controller \
   --attach-policy-arn=arn:aws:iam::<AWS_ACCOUNT_ID>:policy/AWSLoadBalancerControllerIAMPolicy \
   --override-existing-serviceaccounts \
   --region <region-code> \
   --approve
   

Ensure the IAM Policy is attached to the role

5. Install Controller
- Add the Helm repo
```
helm repo add eks https://aws.github.io/eks-charts
```

- Install
```
helm install aws-load-balancer-controller eks/aws-load-balancer-controller -n kube-system --set clusterName=<cluster-name> --set serviceAccount.create=false --set serviceAccount.name=aws-load-balancer-controller --set region=<region of cluster> --set vpcId=<vpc id of cluster>
```

- Wait for the installation of controller
```
kubectl get deploy -n kube-system -w
```

- Check the ingress resource to view the loadbalancer DNS
```
kubectl get ingress -n motd-ns
```

- View logs of controller if alb is not created
```
kubectl logs -n kube-system -l app.kubernetes.io/name=aws-load-balancer-controller
```
