Containerized Deployments: A Step-by-Step Guide to Deploying A Docker Image Using ECS and 2048 Game Application using EKS

#webdev #kubernetes #containers #aws

Introduction

Containerization has revolutionized the way we deploy applications, providing a lightweight, portable, and efficient way to package software. AWS offers two powerful container orchestration services: Elastic Container Service (ECS) and Elastic Container Service for Kubernetes(EKS). In this guide, we'll walk through the process of deploying a docker image using ECS and a game application using EKS. Without wasting much time, let's dive in to today's project.

Part 1: Deploying A Docker Image Using ECS

Step 1: Create an ECS Cluster

Login to your AWS Management Console
Search for ECS and click on it
Click on cluster by your left
Click on create cluster
Name your cluster

Click on create

After creating the cluster, click on ECR by your left ( open it in a new tab)
Click on get started
Click on repositories by your left
click on create repository and create

Open your terminal (preferably, using AWS CLI)
Clone or fork this GitHub repo GitHub, then click on command.md
Copy the login command from command.md
paste it on your terminal -Remove.dkr.ecr.amazonaws.com
Go to the repository you created in your AWS
Copy the repo URL and paste it where you remove those things, and put your AWS region where you see region close to /docker
Go back to the GitHub and copy the command for build docker image from command.md and paste it in your terminal
Remove.dkr.ecr.amazonaws.com and replace it with your repo URL.
Go back to the GitHub and copy the push image command, and paste it in your terminal
Remove the.dkr.ecr.amazonaws.com and replace it with your repo URL. Remove the dot (.) by the end of latest then hit enter
After creating and pushing, go back to your ECR, click on task definition by your left
Click on create task definition
Name the task
Scroll down to memory and reduce it (optional though)
Scroll down to task execution role
Click the drop-down button and select create new role (because we want to integrate cloud watch)
Scroll down to container details
Name the container
Paste your repo URL in image URL at the end of the URL, put :latest
Put your port number under container port
Choose http under app protocol
Click on create
After creating the task definition, click on it to see if it is active
If it is active, click on deploy drop down above and select run task
Under existing cluster put your cluster
Then click on create

Part 2: Deploying 2048 Game Application Using EKS

Step 1: Install EKSCTL

Before installing EKSCTL, ensure you have AWS CLI installed and configured in your laptop
After installing your EKSCTL, open it and create cluster
Here is the command for your Cluster creation Cluster. Behind --name, remove demo-cluster and put the name of what you want to name your cluster. Where you see region, remove US-east-1 and put your region then hit enter

Go to your AWS, search for cluster, you will see your cluster

Note: Using EKSCTL to create cluster is very fast because it will create everything including network automatically

Go to your AWS Management Console and search for EKS, and click on it
You will see your cluster you just created
Go back to your EKSCTL and type aws eks update-kubeconfig--name your cluster name--region your region, then hit enter
Now let's deploy our app
Go to the GitHub
Click on 2048-app-deploy
Copy everything under create fargate profile
Paste it in your EKSCTL

Change the region to your region and the cluster name hit enter
Go to your cluster in your AWS, scroll down to fargate profile to see if the fargate profile you created is there

Cluster and fargate created
Go to the GitHub, and click on 2048-app
Copy deploy the deployment URL
Paste it in your EKSCTL enter ( this is to deploy ingress)
Type kubectl get pods -n game-2048 -w enter (to see if the ingress has been created)

Type kubectl get svc -n gameb-2048 enter (to see if the service is running)
Type kubectl get ingress -n game-2048 enter

Now let's create ingress controller
Go to GitHub
Click on configure oidc connector.md
Copy the command to configure IAM OIDC PROVIDER (eksctl utils associate)

Paste it in your EKSCTL terminal. Change the cluster name to your cluster name
Go to here GitHub
Click on alb controller and copy the command for download IAM policy
Paste it in your EKSCTL terminal enter
Go back to the alb controller in the GitHub, cpy the create IAM Role command
Paste it in your EKSCTL terminal
Where you see put your AWS account ID there. Put your cluster name where you see cluster name
Copy the helm command from alb controller too
paste it in your EKSCTL terminal
Go to your cluster in your AWS
Click on network
Copy the VPC info
Go back to your EKSCTL terminal, remove the VPC id you see and paste yours
Put your region
Put your cluster name enter
Go to your AWS cluster, click on network and you will see your VPC created
