Integrating Kubernetes with AWS Container Registry (ECR)

Pre-Lab Preparation

  • Amazon EKS Cluster is running

  • kubectl is configured

  • AWS CLI is configured

  • Docker is installed

  • EC2 administration server is available

  • ECR permissions are available

Task 1: Verify AWS and Kubernetes Connectivity

Verify AWS account:

aws sts get-caller-identity

Verify EKS cluster:

kubectl cluster-info

Verify nodes:

kubectl get nodes

Task 2 : Create Amazon ECR Repository

Open AWS Console.

Navigate to: Elastic Container Registry (ECR)

Click: Create Repository

Repository Configuration

Repository Name: opsmate

Click: Create Repository

After creation, copy Repository URI.

Example:123456789012.dkr.ecr.us-east-1.amazonaws.com/opsmate

Keep this value for later steps.

Task 3 : Create Sample OpsMate Application

Create project directory

mkdir opsmate
cd opsmate

git clone https://github.com/mantu0tech/front-end.git

Task 4: Create Dockerfile

Create Dockerfile

Task 5: Build Docker Image

Build image

docker build -t opsmate:v1 .

Verify image

docker images

Test locally

docker run -d -p 3000:3000 opsmate:v1

Open browser:http://localhost:3000

Task 6 :  Authenticate Docker with ECR

Login to ECR

aws ecr get-login-password --region ap-south-1 | docker 
login --username AWS
 --password-stdin 051826716700.dkr.ecr.ap-south-1.amazonaws.com

Task 7: Tag Docker Image

Tag image with repository URI

docker tag opsmate:v1 051826716700.dkr.ecr.ap-south-1.amazonaws.com/opsmate:v1

Verify

docker images

Task 8: Push Image to ECR

Push image

docker push 123456789012.dkr.ecr.us-east-1.amazonaws.com/opsmate:v1

Verify image upload: AWS Console →ECR → Repositories → opsmate

Task 9: Create Namespace for OpsMate

Create namespace:

kubectl create namespace opsmate

Verify:

kubectl get ns

Set namespace context

kubectl config set-context --current --namespace=opsmate

Task 10: Create Kubernetes Deployment

Create deployment file:

nano deployment.yaml

Apply deployment

kubectl apply -f deployment.yaml

Task 11: Expose Application

Create service

nano service.yaml

Apply service

kubectl apply -f service.yaml

Task 12 : Verify Application Access

Open browser:

Task 13 : Verify Running Resources

Check Pods

kubectl get pods -o wide

Check Logs

kubectl logs opsmate-app-974887687-qd4cl

Check all resources

kubectl get all

Describe Deployment

kubectl describe deployment opsmate-app

 

Great job!

  • Created Amazon ECR repository

  • Built OpsMate Docker image

  • Authenticated Docker with ECR

  • Tagged and pushed images to ECR

  • Created Kubernetes Deployment using ECR image

  • Exposed application using LoadBalancer Service

  • Verified application accessibility

  • Updated application image and performed deployment update
