Docker Magento Deployment with Kubernetes

Magento is a powerful and flexible platform for building eCommerce applications. However, deploying Magento in a cloud-native environment requires robust tools and best practices to ensure high availability, scalability, and smooth development workflows. Two technologies that make this possible are Docker and Kubernetes. This guide will walk through the process of containerizing Magento with Docker and orchestrating its deployment using Kubernetes in a production-ready setup.

Why Use Docker for Magento?

Docker enables you to bundle Magento, along with all its required software libraries and tools, into containerized environments. These containers are isolated, lightweight, and portable, helping developers maintain environmental consistency across machines and teams. Advantages of using Docker for Magento:

Identical setup in every environment.

Faster onboarding with pre-built container images.

Isolated dependencies, avoiding version conflicts.

Sample Dockerfile to Run Magento

Below is an example Dockerfile to prepare a Magento containerized image:

`
# Start from PHP 8.1 FPM base image 
FROM php:8.1-fpm 
# Install required PHP extensions and tools 
RUN apt-get update && apt-get install -y \ 
	git unzip libzip-dev libpng-dev libonig-dev libxml2-dev \ 
	&& docker-php-ext-install pdo_mysql zip gd 
 
# Set working directory 
WORKDIR /var/www/html 
 
# Copy project files into the container 
COPY . . 
 
# Install dependencies using Composer 
RUN composer install 
 
# Expose port 9000 for PHP-FPM 
EXPOSE 9000 
 
# Start PHP-FPM server 
CMD ["php-fpm"]

Scaling Magento with Kubernetes

Kubernetes (K8s) simplifies running Magento containers at scale by handling automatic scaling of pods, self-healing in case of failures, and rolling deployments without downtime.

Essential Kubernetes Concepts for Magento

Pods: Run your Magento containers.

Services: Provide stable endpoints to access pods.

PersistentVolumes: Retain MySQL data or media assets.

Kubernetes Deployment YAML for Magento App

Here’s an example deployment to run a Magento app on Kubernetes:

`
# Magento application deployment 
apiVersion: apps/v1 
kind: Deployment 
metadata: 
  name: magento-app-deployment 
spec: 
  replicas: 2 
  selector: 
	matchLabels: 
  	component: magento-app 
  template: 
	metadata: 
  	labels: 
    	component: magento-app 
	spec: 
  	containers: 
  	- name: magento-container 
    	image: custom-registry/magento:latest 
    	ports: 
    	- name: http 
      	containerPort: 9000

Architecture Overview

A typical Magento stack deployed in Kubernetes includes:

PHP-FPM Pods for serving Magento code.

MySQL for the backend database.

Redis for cache and session handling.

Elasticsearch for product search.

RabbitMQ for async operations like order queues.

Persistent Volume for MySQL.

Below is a PersistentVolumeClaim (PVC) definition used for MySQL database storage

`
apiVersion: v1 
kind: PersistentVolumeClaim 
metadata: 
  name: magento-mysql-claim 
spec: 
  accessModes: 
	- ReadWriteOnce 
  resources: 
	requests: 
  	storage: 20Gi

MySQL Deployment for Magento. Here’s how you can deploy MySQL in Kubernetes

# MySQL deployment with volume and credentials

`
apiVersion: apps/v1 
kind: Deployment 
metadata: 
  name: magento-mysql 
spec: 
  replicas: 1 
  selector: 
	matchLabels: 
  	component: mysql-db 
  template: 
	metadata: 
  	labels: 
    	component: mysql-db 
	spec: 
  	containers: 
  	- name: mysql-instance 
    	image: mysql:5.7 
    	env: 
    	- name: ROOT_DB_PASSWORD 
      	valueFrom: 
        	secretKeyRef: 
          	name: mysql-auth 
          	key: root-pass 
    	volumeMounts: 
    	- name: mysql-storage 
      	mountPath: /var/lib/mysql 
  	volumes: 
  	- name: mysql-storage 
    	persistentVolumeClaim: 
      	claimName: magento-mysql-claim

Automating Deployments with CI/CD

To streamline deployment, use CI/CD pipelines. These automate: Building Docker

Running unit or integration tests, pushing images to a registry deploying via kubectl or Helm.

GitHub Actions Workflow for Magento CI/CD

# Automated pipeline for Magento app deployment

`
name: Magento AutoDeploy 
on: 
  push: 
	branches: 
	- main 
jobs: 
  magento-deploy: 
	runs-on: ubuntu-latest 
	steps: 
	- name: Sync Source Code 
  	uses: actions/checkout@v3 
	- name: Assemble Docker Image 
  	run: docker build -t magento-app:latest . 
	- name: Transfer Image to Repo 
  	run: docker push magento-app:latest 
	- name: Launch to Kubernetes 
  	run: kubectl apply -f ./kube/deployment.yaml

Docker Magento Setup – Scale Your Store Easily

The Way Forward

By containerizing Magento and leveraging Kubernetes, organizations can achieve a modern and robust infrastructure that is scalable, fault-tolerant, and developer-friendly. CI/CD tools, such as GitHub Actions, further reduce manual deployment effort, enabling the continuous delivery of features with confidence. Whether you’re building a small eCommerce site or scaling to millions of users, combining Docker, Kubernetes, and CI/CD provides the backbone for secure and efficient Magento operations.
