WordPress Docker Setup

This repository contains a Docker setup for deploying a WordPress site with Nginx as a reverse proxy and Let's Encrypt for SSL certificates. It uses Docker Compose to manage multiple services, including WordPress, MySQL, Nginx, and Let's Encrypt.

Overview

The setup includes the following services:

• WordPress: The WordPress application, built from a custom Dockerfile.
• MySQL: A MySQL database for WordPress.
• Nginx Proxy: An Nginx reverse proxy to handle incoming requests and route them to the WordPress container.
• Let's Encrypt: A companion container for automatically managing SSL certificates.

Prerequisites

• Docker: Install Docker
• Docker Compose: Install Docker Compose

Configuration

Dockerfile

The Dockerfile is used to build a custom WordPress image. It copies your WordPress code into the image and sets the correct file permissions.

docker-compose.yml

The docker-compose.yml file defines the services and their configurations:

• nginx-proxy: Handles HTTP and HTTPS traffic and routes requests to the appropriate container.
• letsencrypt: Manages SSL certificates for the domain specified in VIRTUAL_HOST.
• wordpress: Runs the WordPress application using the custom image built from the Dockerfile.
• db: Provides a MySQL database for WordPress.

Volumes

The setup uses Docker volumes to persist data:

• wordpress_data: Stores WordPress files.
• db_data: Stores MySQL data.
• nginx_certs, nginx_vhost, nginx_html: Used by Nginx and Let's Encrypt.

Getting Started

1. Clone the Repository

   git clone https://github.com/roshank8s/wordpress-docker-image-build-ssl.git
   cd wordpress-docker-image-build-ssl
   

Update the Configuration

Edit the docker-compose.yml file to set your domain and email address for Let's Encrypt. Ensure your WordPress code is placed in the directory specified in the Dockerfile.

Build and Start the Services

docker-compose up --build -d

This command builds the custom WordPress image and starts all the services in detached mode.

Access Your WordPress Site

Open your web browser and navigate to your domain (e.g., http://www.example.com). You should see the WordPress setup page.

Updating Your WordPress Code

To update your WordPress code, modify the files in the directory specified in the Dockerfile and rebuild the image:

docker-compose build wordpress docker-compose up -d

Troubleshooting

Check Logs: Use docker-compose logs to view logs for debugging. Restart Services: Restart services with docker-compose restart.
