Containerizing & Orchestrating a Full-Stack E-commerce Platform with Docker and Kubernetes

Jenkins

Source: Dev.to | Jan 10, 2026 (UTC)

The diagram below provides a visual representation of the services used in this setup to deploy the EasyShop application. This project is hosted on a local Virtual machine, which serves as the base infrastructure. We utilize Docker to build application images and to run Kind (Kubernetes in Docker), which creates a lightweight Kubernetes cluster within the Local VM.

The application images are stored in Docker Hub. Within the Kind cluster, external traffic is managed by the NGINX Ingress Controller, which routes requests to the EasyShop application pods. The application then connects to a MongoDB StatefulSet for data persistence.

What Do We Need?

  • Local VM (Ubuntu x64): A virtual machine running Ubuntu x64 acts as the primary infrastructure. It serves as the host for deploying the cluster and running all necessary Docker commands.
  • Git & GitHub: Git is used for version control to manage the codebase locally, while GitHub serves as the remote repository to host the source code of the EasyShop application.
  • Docker: Used to containerize the application by building Docker Images from the Dockerfile. It is also required to run the Kind nodes, which operate as Docker containers.
  • Docker Hub: The container registry used to store and share the built images (Application and Migration images), making them accessible to the cluster.
  • Kind (Kubernetes in Docker): A tool for running local Kubernetes clusters using Docker container “nodes”. It simulates the production environment inside your local VM.

Prerequisites Installation:

Linux:

Install Docker

curl -fsSL https://get.docker.com -o get-docker.sh sudo sh get-docker.sh rm get-docker.sh

Enter fullscreen mode

Exit fullscreen mode

Install Kind

curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.27.0/kind-linux-amd64 chmod +x ./kind sudo mv ./kind /usr/local/bin/kind

Enter fullscreen mode

Exit fullscreen mode

Install kubectl

curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl" chmod +x kubectl sudo mv ./kubectl /usr/local/bin/kubectl

Exit fullscreen mode

Environment Setup

  1. Clone the repository and navigate to the project directory

git clone https://github.com/YadneshR/Easy_Shop_Containerization_and_Orchestration.git cd EasyShop

Enter fullscreen mode

Exit fullscreen mode

  1. Build and Push Docker Images

First, login to Docker Hub (create an account at hub.docker.com if you haven’t :

docker login

Enter fullscreen mode

Exit fullscreen mode

Build Application Image

# Build the application image docker build -t your-dockerhub-username/easyshop:latest .

Enter fullscreen mode

Exit fullscreen mode

# Push to Docker Hub docker push your-dockerhub-username/easyshop:latest

Enter fullscreen mode

Exit fullscreen mode

Build Migration Image

# Build the migration image docker build -t your-dockerhub-username/easyshop-migration:latest -f Dockerfile.migration /scripts .

Enter fullscreen mode

Exit fullscreen mode

# Push to Docker Hub docker push your-dockerhub-username/easyshop-migration:latest

Enter fullscreen mode

Exit fullscreen mode

Kind Cluster Setup

Create new cluster

kind create cluster --name easyshop --config kubernetes/00-kind-config.yaml

Enter fullscreen mode

Exit fullscreen mode

This command creates a new Kind cluster using our custom configuration with one control plane.

Create namespace

kubectl apply -f kubernetes/01-namespace.yaml

Enter fullscreen mode

Exit fullscreen mode

Setup storage

kubectl apply -f kubernetes/02-mongodb-pv.yaml kubectl apply -f kubernetes/03-mongodb-pvc.yaml

Enter fullscreen mode

Exit fullscreen mode

Create ConfigMap

Create kubernetes/04-configmap.yaml with the following content:

apiVersion: v1 kind: ConfigMap metadata: name: easyshop-config namespace: easyshop data: MONGODB_URI: "mongodb://mongodb-service:27017/easyshop" NODE_ENV: "production" NEXT_PUBLIC_API_URL: "http://easyshop.local/api" # Add custom local domain or EC2 ip NEXTAUTH_URL: "http://easyshop.local" # Add custom local domain or EC2 ip NEXTAUTH_SECRET: "Generate your own NEXTAUTH secret" JWT_SECRET: "Generate your own JWT secret"

Enter fullscreen mode

Exit fullscreen mode

ADD CUSTOM DOMAIN IF ON LOCAL VM

vim /etc/hosts

Enter fullscreen mode

Exit fullscreen mode

Add this line at the bottom in the file

127.0.0.1 easyshop.local

Enter fullscreen mode

Exit fullscreen mode


Verify :

ping easyshop.local

Enter fullscreen mode

Exit fullscreen mode

To generate secure secret keys, use these commands in your terminal:

# For NEXTAUTH_SECRET openssl rand -base64 32 # For JWT_SECRET openssl rand -hex 32

Enter fullscreen mode

Exit fullscreen mode

After making changes in configmap.yml

kubectl apply -f kubernetes/04-configmap.yaml

Enter fullscreen mode

Exit fullscreen mode

Setup configuration

kubectl apply -f kubernetes/05-secrets.yaml

Enter fullscreen mode

Exit fullscreen mode

Deploy MongoDB

kubectl apply -f kubernetes/06-mongodb-service.yaml kubectl apply -f kubernetes/07-mongodb-statefulset.yaml

Enter fullscreen mode

Exit fullscreen mode

Deploy EasyShop

Make necessary changes such as:

kubectl apply -f kubernetes/08-easyshop-deployment.yaml

Enter fullscreen mode

Exit fullscreen mode

kubectl apply -f kubernetes/09-easyshop-service.yaml

Enter fullscreen mode

Exit fullscreen mode

Install NGINX Ingress Controller

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml

Enter fullscreen mode

Exit fullscreen mode

Deploy Ingress and HPA

Make necessary changes such as:

kubectl apply -f kubernetes/10-ingress.yaml kubectl apply -f kubernetes/11-hpa.yaml

Enter fullscreen mode

Exit fullscreen mode

Update Migration Job with your docker image :

apiVersion: batch/v1 kind: Job metadata: name: db-migration namespace: easyshop spec: template: spec: containers: - name: migration image: your_username/easyshop-migration:latest # update with the name that you have build. imagePullPolicy: Always env: - name: MONGODB_URI value: "mongodb://mongodb-service:27017/easyshop" restartPolicy: OnFailure

Enter fullscreen mode

Exit fullscreen mode

# Run database migration kubectl apply -f kubernetes/migration-job.yaml

Enter fullscreen mode

Exit fullscreen mode


Verify it on your machine browser

http://easyshop.local

Enter fullscreen mode

Exit fullscreen mode
