How do you set up FuelPHP with Docker for development?

To set up FuelPHP with Docker for development, follow these detailed steps:

1. Create a Dockerfile

The first step is to create a Dockerfile that will define your application’s environment. In this example, we are using the official PHP image with Apache and setting up PDO for MySQL:

Example

<?php
# Use the PHP 7.4 Apache image
FROM php:7.4-apache

# Install necessary PHP extensions
RUN docker-php-ext-install pdo pdo_mysql

# Copy all files from the current directory to /var/www/html in the container
COPY . /var/www/html

# Set the working directory in the container
WORKDIR /var/www/html
?>

This Dockerfile:

  • Uses PHP 7.4 with Apache as the base image.
  • Installs PDO extensions for MySQL to connect to databases.
  • Copies your application code from your local machine into the container’s /var/www/html directory.

2. Create a Docker Compose File

Next, create a docker-compose.yml file to orchestrate your services. This file will define the services (e.g., the web app) and how they interact.

Example

<?php
version: '3.8'
services:
  app:
    build: .
    ports:
      - "8080:80"
    volumes:
      - .:/var/www/html
    environment:
      - APACHE_DOCUMENT_ROOT=/var/www/html/public
?>

Key points in this configuration:

  • build: . tells Docker Compose to build the image using the Dockerfile in the current directory.
  • Ports: 8080:80 maps port 80 of the container to port 8080 on your local machine. You will access the app via http://localhost:8080.
  • Volumes: This mounts the current directory into the container, so any changes you make to your local files will immediately reflect in the container.
  • APACHE_DOCUMENT_ROOT: This sets the Apache document root to the public folder, which is the default for FuelPHP applications.

3. Set Up Your FuelPHP Application

Now, create or clone your FuelPHP application in the same directory where the Dockerfile and docker-compose.yml are located. You can clone an existing FuelPHP repository or create a new one:

Example

git clone https://github.com/fuel/fuel fuelphp-app
cd fuelphp-app

Ensure the public directory exists, as that’s where FuelPHP serves content.

4. Run Docker

Open your terminal, navigate to the project directory (where the Dockerfile and docker-compose.yml are), and run the following command to start your application:

Example

docker-compose up -d
  • -d runs the containers in detached mode, meaning the app will run in the background.

Docker will build your image, create the container, and start your FuelPHP app.

5. Access the Application

After Docker finishes setting up, open a browser and go to:

Example

http://localhost:8080

Example Project Structure:

Here’s how your project structure will look after completing the above steps:

Example

fuelphp-app/
│
├── Dockerfile
├── docker-compose.yml
├── public/
│   └── index.php
├── fuel/
├── app/
└── other_fuelphp_files

6. Additional Configuration (Optional)

  • Database Setup: If your FuelPHP app requires a database, you can add a MySQL service to your docker-compose.yml like this:

Example

version: '3.8'
services:
  app:
    build: .
    ports:
      - "8080:80"
    volumes:
      - .:/var/www/html
    environment:
      - APACHE_DOCUMENT_ROOT=/var/www/html/public

  db:
    image: mysql:5.7
    volumes:
      - db-data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root_password
      MYSQL_DATABASE: fuelphp_db
      MYSQL_USER: fuelphp_user
      MYSQL_PASSWORD: user_password

volumes:
  db-data:

FuelPHP Configuration: Update fuel/app/config/development/db.php with your database credentials:

Example

return array(
  'default' => array(
    'type' => 'mysql',
    'connection'  => array(
      'hostname' => 'db',
      'database' => 'fuelphp_db',
      'username' => 'fuelphp_user',
      'password' => 'user_password',
    ),
  ),
);
