PHP Docker and containerization

Docker enables consistent, portable deployment of PHP applications across different environments through containerization. It simplifies deployment, testing and scalability: Install Docker on your local machine. Create a PHP container that contains a Dockerfile with instructions for building the container. Run the container, exposing ports to access the application. For Laravel applications, install dependencies and run docker-compose up to build and run the container. Docker offers many benefits, including portability, scalability, security, faster development and testing.

PHP Docker and Containerization

Introduction

Docker is a platform that enables containers for applications ization to provide consistent, portable software delivery across a variety of environments. For PHP applications, Docker simplifies deployment, testing, and scalability, making it an invaluable tool for modern application development.

Install Docker

Install Docker on your local machine. For detailed instructions, see [Docker official documentation](https://docs.docker.com/install/).

Building PHP Containers

1. Create a Dockerfile with the following content:

FROM php:8.0-apache

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

COPY . /var/www/html

2. Create a php-app directory that contains your PHP application files.

Run Container

Use the following commands to build and run the container:

docker build -t php-app .
docker run -p 80:80 php-app

Practical Case: Deploying Laravel Application

1. Create a Laravel project.

2. In Dockerfile, add the following lines to install the Laravel dependencies:

RUN composer install

3. Run docker-compose up to build and run the container.
4. To access your application, navigate in your browser to http://localhost/ or your server’s IP address.

Benefits

Using Docker to containerize PHP applications has many benefits, including:

• Consistent and portable Deployment
• Easy scalability and failover
• Improved security
• Faster development and testing cycles
