Docker PHP-FPM 8.3 & Nginx 1.26 on Alpine Linux

Example PHP-FPM 8.3 & Nginx 1.26 container image for Docker, built on Alpine Linux.

Repository: https://github.com/TrafeX/docker-php-nginx

Built on the lightweight and secure Alpine Linux distribution
Multi-platform, supporting AMD4, ARMv6, ARMv7, ARM64
Very small Docker image size (+/-40MB)
Uses PHP 8.3 for the best performance, low CPU usage & memory footprint
Optimized for 100 concurrent users
Optimized to only use resources when there's traffic (by using PHP-FPM's on-demand process manager)
The services Nginx, PHP-FPM and supervisord run under a non-privileged user (nobody) to make it more secure
The logs of all the services are redirected to the output of the Docker container (visible with docker logs -f <container name>)
Follows the KISS principle (Keep It Simple, Stupid) to make it easy to understand and adjust the image to your needs

I can help you with Containerization, Kubernetes, Monitoring, Infrastructure as Code and other DevOps challenges.

Goal of this project

The goal of this container image is to provide an example for running Nginx and PHP-FPM in a container which follows the best practices and is easy to understand and modify to your needs.

Usage

Start the Docker container:

docker run -p 80:8080 trafex/php-nginx

See the PHP info on http://localhost, or the static html page on http://localhost/test.html

Or mount your own code to be served by PHP-FPM & Nginx

docker run -p 80:8080 -v ~/my-codebase:/var/www/html trafex/php-nginx

Versioning

Major or minor changes are always published as a release with correspondending changelogs. The latest tag is automatically updated weekly to include the latests patches from Alpine Linux.

Configuration

In config/ you'll find the default configuration files for Nginx, PHP and PHP-FPM. If you want to extend or customize that you can do so by mounting a configuration file in the correct folder;

Nginx configuration:

docker run -v "`pwd`/nginx-server.conf:/etc/nginx/conf.d/server.conf" trafex/php-nginx

PHP configuration:

docker run -v "`pwd`/php-setting.ini:/etc/php83/conf.d/settings.ini" trafex/php-nginx

PHP-FPM configuration:

docker run -v "`pwd`/php-fpm-settings.conf:/etc/php83/php-fpm.d/server.conf" trafex/php-nginx

Note; Because -v requires an absolute path I've added pwd in the example to return the absolute path to the current directory
