Docker php:8.2-apache on Alpine Linux

Example PHP-FPM 8.2-apache setup for Docker, build on Alpine Linux. The image is only +/- 25MB large.

Built on the lightweight and secure Alpine Linux distribution
Very small Docker image size (+/-65MB)
Uses PHP 8.2 for better performance, lower cpu usage & memory footprint
Multi-arch support: 386, amd64, arm/v6, arm/v7, arm64, ppc64le, s390x
Optimized for 100 concurrent users
Optimized to only use resources when there's traffic (by using PHP-FPM's ondemand PM)
Use of runit instead of supervisord to reduce memory footprint
The servers Nginx, PHP-FPM 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

Usage

Start the Docker container:

docker run -p 80:8080 kerstinsieren/alpine-phpfpm-nginx-baseimage

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 8080:80 -v ~/my-codebase:/var/www/html kerstinsieren/alpine-phpfpm-nginx-baseimage
