WordPress Composer Kubernetes Setup

This repository contains a WordPress setup using Composer for dependency management, Docker for local development, and Kubernetes for production deployment.

Prerequisites

1. Install required software:
   • Docker Desktop
   • Git

That's it! No need for PHP or Composer locally - everything is handled via Docker.

Initial Setup

1. Clone the repository:

git clone [repository-url]
cd wordpress-composer-k8s

2. Create the required directory structure:

mkdir -p web/app/plugins
mkdir -p config/nginx

3. Start the local environment:

docker-compose -f docker-compose.override.yml up -d

4. Access WordPress at http://localhost:8080

How it works

• The Dockerfile uses a multi-stage build:
  1. First stage uses the Composer image to install dependencies
  2. Second stage uses WordPress PHP-FPM image
  3. All PHP and Composer operations happen inside Docker containers
• No need to install PHP or Composer locally
• All dependencies are managed within Docker

Production Deployment

Option 1: Manual Deployment

1. Ensure you have access to a Kubernetes cluster
2. Deploy using Helm:

helm install wordpress ./helm/wordpress

Option 2: Automated Deployment

1. Push your code to GitHub
2. The GitHub Actions workflow will automatically:
   • Build a Docker image
   • Push to Docker Hub
   • Deploy to your Kubernetes cluster
