Dockerized PHP Application with Nginx, MySQL, Redis, and PHPMyAdmin

This repository contains a Dockerized setup for a PHP application. It includes the following services:

• Nginx: Serves as the reverse proxy and web server.
• PHP-FPM: Runs your PHP application.
• MySQL: The database for storing application data.
• Redis: For in-memory caching.
• PHPMyAdmin: A web-based GUI for managing the MySQL database.

Configuration

.env File

The .env file is used to configure environment variables. Below is an example of its contents:

APP_NAME=my-app
PROJECT_HTTP_PORT=8080
ROOT_DIR=./src
MYSQL_PORT=3306
MYSQL_USER=root
MYSQL_ROOT_PASSWORD=securepassword
REDIS_PORT=6379
PHPMYADMIN_PORT=8081
PHPMYADMIN_FILE_UPLOAD=true
PHPMYADMIN_UPLOAD_LIMIT=10M
PHPMYADMIN_MEMORY_LIMIT=128M
PHPMYADMIN_POST_MAX_SIZE=20M
PHPMYADMIN_MAX_EXECUTION_TIME=60
PHPMYADMIN_PMA_ARBITARY=1

Usage

1.Clone the Repository:

git clone <repository-url>
cd <repository-name>

2.Build and Start the Services:

docker-compose up --build

3.Access the Application:

• PHP Application: http://localhost:8080 (default port)
• PHPMyAdmin: http://localhost:8081 (default port)

4.Stop the Services:

docker-compose down

Customization

• Modify Nginx Configuration : Edit the docker/nginx/app.conf file to update Nginx settings as needed.

• Modify PHP Configuration : Update docker/php/php.ini to change PHP settings such as memory limit, execution time, etc.

• Add More Services : Add additional services to the docker-compose.yml file as needed for your project.

Data Persistence

• MySQL Data: Stored in ./docker/.data/mysql (ensure this directory is backed up for persistent data).
• Application Code: Mapped from the host system using the ROOT_DIR variable in the .env file.

Troubleshooting

• Service Logs: To view logs for a specific service:

docker-compose logs <service-name>

• Rebuild Containers: If you encounter issues, rebuild the containers:

docker-compose up --build

• Database Connection Issues: Ensure the MySQL environment variables (MYSQL_USER, MYSQL_ROOT_PASSWORD) in the .env file are correctly set.
