Deploying Tetris on Kubernetes with Argo CD

Prerequisites

Before we begin, make sure you have the following:

1. An AWS account.

2. eksctl installed on your local machine.

3. kubectl installed on your local machine.

4. Git for version control.

5. https://archive.eksworkshop.com/intermediate/290_argocd/configure/

Step 1: Create an EKS Cluster

Use the following eksctl command to create an EKS cluster named "dev" in the EU (Stockholm) region with a managed node group:

eksctl create cluster --name dev --region eu-north-1 --nodegroup-name workers --node-type t3.medium --nodes 2 --nodes-min 2 --nodes-max 2 --managed

Wait for the cluster to be provisioned before proceeding.

Step 2: Install Argo CD

Create a namespace for Argo CD and apply the installation manifests:

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml

Patch the Argo CD service to use a LoadBalancer:

kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'

Retrieve the external IP or DNS of the Argo CD server:

kubectl get svc argocd-server -n argocd -o=jsonpath='{.status.loadBalancer.ingress[0].hostname}'

Now, you can access the Argo CD UI using the provided external IP or DNS.

export ARGO_PWD=`kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d`
echo $ARGO_PWD

Step 3: Deploy Tetris Game with Argo CD

Clone the Tetris game repository:

git clone https://github.com/muhammadhassanb111/tetris-game/tree/main
