Deploying Super Mario Game on Kubernetes (EKS)

Mario is widely considered the most famous video game character in history. He has appeared in a variety of merchandise, such as clothing and collectible items, and people and places have been nicknamed after him. He has also inspired a considerable amount of unofficial media.

Steps:

1. Ec2 Instance
2. IAM role
3. Cluster Provision
4. Terraform
5. Elastic Kubernetes Service (Amazon EKS)

Create a Ec2 Instance

1. Sign in to AWS Console
2. Navigate to EC2 Dashboard
3. Launch Instance
4. Choose an Amazon Machine Image (AMI) → you can choose “Ubuntu” image.
5. Choose an Instance Type → Select t2.micro as your instance type.
6. Configure Instance Details
7. Add Tags (Optional)
8. Configure Security Group
9. Review and Launch
10. Select Key Pair
11. Access the EC2 Instance

Create IAM role

Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. With IAM, you can centrally manage permissions that control which AWS resources users can access.

Role → Create role → AWS service → Service (Ec2) → Permission (Administrator access) → Create a role

Attach this role to Ec2 instance

Actions → Security → Modify IAM role

Select the Role that created earlier and click on Update IAM role.

Cluster provision

1. Now clone this Repo.
   git clone https://github.com/Ibrahimsi/k8s-mario.git
2. Provide the executable permission to script.sh file, and run it

chmod +x script.sh

Run the Script

./script.sh

This script will install AWS cli, Kubectl, Terraform

./script.sh run the command

#!/bin/bash
# Install AWS CLI 
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
sudo apt-get install unzip -y
unzip awscliv2.zip
sudo ./aws/install

# Install kubectl
sudo apt update
sudo apt install curl -y
curl -LO https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl
sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
kubectl version --client

# Install Terraform
sudo apt install wget -y
wget -O- https://apt.releases.hashicorp.com/gpg | sudo gpg --dearmor -o /usr/share/keyrings/hashicorp-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
sudo apt update && sudo apt install terraform -y

echo "Installation completed successfully."

Check Version

aws --version
kubectl version --client
terraform --version

Change directory into the EKS-TF

NOTE: Don’t forgot to change the s3 bucket name in the backend.tf file

Terraform

Initializes the Terraform working directory, downloading any necessary provider plugins

terraform init

Terraform Validate runs checks that verify whether a configuration is syntactically valid and internally consistent, regardless of any provided variables or existing state.

terraform validate

Terraform plan command creates an execution plan, which lets you preview the changes that Terraform plans to make to your infrastructure.

When Terraform creates a plan it → Reads the current state of any already-existing remote objects to make sure that the Terraform state is up-to-date.

Run terraform apply to provision cluster

terraform apply --auto-approve

It will take more than 10 minutes

Elastic Kubernetes Service (Amazon EKS)

Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes service that makes it easy for you to run Kubernetes on AWS and on-premises.

EKS provides an integrated console for Kubernetes clusters. Cluster operators and application developers can use EKS as a single place to organize, visualize, and troubleshoot your Kubernetes applications running on Amazon EKS.

The EKS console is hosted by AWS and is available automatically for all EKS cluster

Update the Kubernetes configuration and make sure change your desired region.

aws eks update-kubeconfig --name EKS_CLOUD --region ap-south-1

Kubernetes Deployment tells Kubernetes how to create or modify instances of the pods that hold a containerized application. Deployments can help to efficiently scale the number of replica pods, enable the rollout of updated code in a controlled manner, or roll back to an earlier deployment version if necessary.

kubectl apply -f deployment.yaml  #to check the deployment
kubectl get all

List down all the pods, services, statefulsets etc…,

Service.yaml is a method for exposing a network application that is running as one or more Pods in your cluster.

kubectl apply -f service.yaml
kubectl get all

Describe the service and copy the LoadBalancer Ingress

kubectl describe service mario-service

Paste the ingress link in a browser and you will see the Mario game.

Remove the service and deployment first

kubectl delete service mario-service
kubectl delete deployment mario-deployment

Destroy the cluster

terraform destroy --auto-approve
