?? "Mastering AWS EKS with Fargate – A Step-by-Step Guide!"

Steps to Set Up AWS EKS with Fargate and Deploy an Application

? 1. Install and configure AWS CLI

• Install AWS CLI (aws configure to set up credentials).
• Ensure IAM user has necessary permissions (EKS, Fargate, IAM, S3, etc.).

? 2. Install and configure eksctl, then create an EKS cluster with Fargate

• Install eksctl and verify it (eksctl version).
• Create an EKS cluster with Fargate using:

eksctl create cluster --name my-cluster --region us-east-1 --fargate        

? 3. Install kubectl and connect to the cluster

• Install kubectl and verify (kubectl version).
• Update Kubeconfig:

aws eks update-kubeconfig --region us-east-1 --name my-cluster        

• Check cluster connectivity:

  kubectl get nodes        

? 4. Add an ALB (Application Load Balancer) with Helm and create IAM roles

• Install Helm and add AWS Load Balancer Controller:

helm repo add eks https://aws.github.io/eks-charts 
helm repo update        

• Create an IAM OIDC provider (if not created by eksctl):

 eksctl utils associate-iam-oidc-provider --region us-east-1 --cluster my-cluster --approve        

• Create IAM policies for ALB Controller:

curl -o iam-policy.json https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/main/docs/install/iam_policy.json aws iam create-policy --policy-name AWSLoadBalancerControllerIAMPolicy --policy-document file://iam-policy.json        

• Create IAM roles and associate them with ALB Controller.

curl -o iam-policy.json https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/main/docs/install/iam_policy.json
aws iam create-policy --policy-name AWSLoadBalancerControllerIAMPolicy --policy-document file://iam-policy.json
        

? 5. Install Ingress Controller and deploy the application

• Install ALB Ingress Controller:

helm install aws-load-balancer-controller eks/aws-load-balancer-controller \
  --set clusterName=my-cluster \
  --set serviceAccount.create=false \
  --set serviceAccount.name=aws-load-balancer-controller \
  -n kube-system
        

• Deploy the application using Kubernetes manifests:

kubectl apply -f deployment.yaml
kubectl apply -f service.yaml
