Caddy, PHP, MySQL, and phpMyAdmin Docker Stack

This repository provides a Docker-based stack with Caddy as the web server, PHP for backend processing, MySQL for the database, and phpMyAdmin for database management.

Prerequisites

Before you start, make sure you have the following installed on your system:

• Docker
• Docker Compose

Services Overview

• PHP: PHP 8.1-FPM is used for backend processing.
• MySQL: MySQL 8.0 serves as the database.
• Caddy: Caddy is used as the web server to serve static files and handle PHP requests.
• phpMyAdmin: phpMyAdmin is included for easy database management.

Directory Structure

. ├── Dockerfile # Docker configuration for PHP service ├── Caddyfile # Configuration for Caddy server ├── docker-compose.yml # Docker Compose configuration ├── public/ # Public directory where the website is served from │ └── index.php # Example PHP file └── README.md # This file

Installation and Setup

1. Clone this repository: git clone https://github.com/vovka93/caddy-php-mysql-stack.git cd caddy-php-mysql-stack

2. Make sure you have the required files (Dockerfile, Caddyfile, and docker-compose.yml) in the project directory.

3. Build and start the services: docker-compose up -d

4. Check if all containers are running: docker-compose ps

5. Access the services:

   • PHP application: Go to http://localhost in your browser.
   • phpMyAdmin: Go to http://localhost:8080 and log in using the following credentials:
     • Username: root
     • Password: rootpassword (as defined in docker-compose.yml)

Managing Containers

• To stop the containers: docker-compose down

• To restart the containers after changes: docker-compose up -d

• To view logs for a specific service (e.g., PHP): docker-compose logs php

Customization

Environment Variables

You can modify the MySQL environment variables in the docker-compose.yml file to use different database credentials:

environment: MYSQL_ROOT_PASSWORD: rootpassword MYSQL_DATABASE: mydatabase MYSQL_USER: user MYSQL_PASSWORD: password

Adding PHP Extensions

To install additional PHP extensions, modify the Dockerfile:

RUN apt-get update && apt-get install -y

&& docker-php-ext-install

Caddy Configuration

Modify the Caddyfile for custom routing or SSL configuration. Example:

:80 { root * /var/www/html/public php_fastcgi php:9000 file_server }

Troubleshooting

• Database connection errors: Ensure the MySQL credentials are correctly set and the MySQL service is running: docker-compose ps

• Port conflicts: Make sure the ports 80, 443, and 8080 are not being used by other applications on your host machine.

• View container logs: Check logs of the failing container for errors: docker-compose logs
