AWS EKS Setup and Deployment of "2048"

This guide will walk you through setting up an AWS EKS cluster using the eksctl command-line utility and deploying the game "2048".

Prerequisites

Before you begin, ensure you have the following installed and configured:

• AWS CLI: The AWS Command Line Interface should be installed and configured with your user account.
• IAM Permissions: Ensure your AWS user account has the necessary IAM permissions to create and manage EKS resources.
• eksctl: The eksctl command-line tool must be installed.
• kubectl: The Kubernetes CLI tool kubectl should be installed.
• helm: The Helm package manager must be installed.

Setup Instructions

1. Create the EKS Cluster

Run the following command to create your EKS cluster:

eksctl create cluster --name <clusterName> \
--region <regionName> \
--nodegroup-name <nodeGroupName> \
--node-type <instanceType> \
--nodes <numberOfNodes> \
--nodes-min <minimumNumberOfNodes> \
--nodes-max <maximumNumberOfNodes>

Example:

eksctl create cluster --name demo-game-2048 \
--region us-east-1 \
--nodegroup-name game-2048-nodes \
--node-type t2.large \
--nodes 2 \
--nodes-min 2 \
--nodes-max 4

The cluster creation process may take up to 15 minutes.

2. Update kubectl Configuration

Once the cluster is ready, update your kubectl configuration to point to the new cluster:

aws eks update-kubeconfig --name <clusterName> \
--region <clusterRegion>

Example:

aws eks update-kubeconfig --name demo-game-2048 \
--region us-east-1

3. Apply Deployment Configuration

Apply the deployment configuration, namespace, service, and ingress resources from the full_2048.yaml file:

kubectl apply -f <fileLocationwithFileName>

Example:

kubectl apply -f ./full_2048.yaml

4. Associate IAM OIDC Provider with the Cluster

Associate an IAM OIDC provider with your cluster to allow it to access AWS resources (e.g., AWS ALB):

eksctl utils associate-iam-oidc-provider --name <clusterName> \
--region <clusterRegion> \
--approve

Example:

eksctl utils associate-iam-oidc-provider --name demo-game-2048 \
--region us-east-1 \
--approve

5. Create IAM Policy

Create an IAM policy using the provided JSON file:

aws iam create-policy --policy-name <policyName> \
--policy-document <urlOrFileLocation>

Example (assuming the policy file is downloaded):

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

6. Create IAM Service Account and Attach Policy

Create an IAM service account and attach the IAM policy created in the previous step:

eksctl create iamserviceaccount \
--cluster <clusterName> \
--region <clusterRegion> \
--namespace kube-system \
--name <serviceAccountName> \
--role-name <roleName> \
--attach-policy-arn arn:aws:iam::<yourAccountID>:policy/<policyName> \
--approve

Example:

eksctl create iamserviceaccount \
--cluster demo-game-2048 \
--region us-east-1 \
--namespace kube-system \
--name aws-load-balancer-controller \
--role-name AWSLoadBalancerControllerRole \
--attach-policy-arn arn:aws:iam::2222111333:policy/AWSLoadBalancerControllerPolicy \
--approve

7. Install AWS Load Balancer Controller

Add the Helm repository and install the AWS Load Balancer Controller:

helm repo add eks https://aws.github.io/eks-charts
helm repo update eks
helm install aws-load-balancer-controller eks/aws-load-balancer-controller \
-n kube-system \
--set clusterName=<clusterName> \
--set serviceAccount.create=false \
--set serviceAccount.name=<serviceAccountName>

Example:

helm install aws-load-balancer-controller eks/aws-load-balancer-controller \
-n kube-system \
--set clusterName=demo-game-2048 \
--set serviceAccount.create=false \
--set serviceAccount.name=aws-load-balancer-controller

To get the public accessible URL, run:

kubectl get ingress -n game-2048

---

That's it! Your AWS EKS cluster is now set up, and the game "2048" is deployed.
