This article demonstrates a containerized full-stack application deployment on AWS EKS, covering local container testing, pushing images to ECR, and Helm-based deployment.
You Should Know:
1. Building and Testing Containers Locally
Use Docker to build and test containers before pushing them to AWS ECR.
Build Docker image docker build -t ecommerce-app:latest . Run container locally for testing docker run -d -p 8080:80 ecommerce-app:latest Verify running containers docker ps
2. Pushing Images to AWS ECR
Authenticate Docker with AWS ECR and push your image.
Login to AWS ECR aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin 123456789012.dkr.ecr.us-east-1.amazonaws.com Tag and push the image docker tag ecommerce-app:latest 123456789012.dkr.ecr.us-east-1.amazonaws.com/ecommerce-app:latest docker push 123456789012.dkr.ecr.us-east-1.amazonaws.com/ecommerce-app:latest
- Deploying on EKS Using Terraform or eksctl
Option 1: Using eksctl (Quick Setup)
Create EKS cluster eksctl create cluster --name ecommerce-cluster --region us-east-1 --nodegroup-name workers --node-type t3.medium --nodes 3 Update kubeconfig aws eks --region us-east-1 update-kubeconfig --name ecommerce-cluster
Option 2: Using Terraform (Infrastructure as Code)
provider "aws" {
region = "us-east-1"
}
module "eks" {
source = "terraform-aws-modules/eks/aws"
cluster_name = "ecommerce-cluster"
cluster_version = "1.27"
subnets = ["subnet-12345678", "subnet-87654321"]
vpc_id = "vpc-12345678"
node_groups = {
eks_nodes = {
desired_capacity = 3
max_capacity = 5
min_capacity = 1
instance_type = "t3.medium"
}
}
}
4. Helm Deployment for EKS
Install Helm and deploy the application.
Install Helm curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 chmod 700 get_helm.sh ./get_helm.sh Add Helm repo and deploy helm repo add bitnami https://charts.bitnami.com/bitnami helm install ecommerce-app bitnami/nginx
5. Verifying Deployment
Check Kubernetes pods and services.
kubectl get pods kubectl get svc
What Undercode Say:
Deploying containerized apps on AWS EKS requires mastering Docker, Kubernetes, and Helm. Automating deployments with Terraform ensures scalability, while eksctl simplifies quick setups. Always test locally before cloud deployment.
Expected Output:
NAME READY STATUS RESTARTS AGE ecommerce-app-5f8b6c4d6-2q7xv 1/1 Running 0 2m NAME TYPE CLUSTER-IP EXTERNAL-IP ecommerce-app LoadBalancer 10.100.10.123 a1b2c3d4e5f6.us-east-1.elb.amazonaws.com
Prediction:
AWS EKS adoption will grow as Kubernetes becomes the standard for cloud-native deployments. Expect tighter integration between ECR, EKS, and CI/CD pipelines for faster DevOps workflows.
