Docker PHP-FPM 7.2 & Nginx 1.14 on Alpine Linux

Example PHP-FPM 7.2 & Nginx 1.14 setup for Docker, build on Alpine Linux. The image is only +/- 35MB large.

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

• Built on the lightweight and secure Alpine Linux distribution
• Very small Docker image size (+/-35MB)
• Uses PHP 7.2 for better performance, lower cpu usage & memory footprint
• Optimized for 100 concurrent users
• Optimized to only use resources when there's traffic (by using PHP-FPM's ondemand PM)
• The servers 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

Breaking changes (26/01/2019)

Please note that the new builds since 26/01/2019 are exposing a different port to access Nginx. To be able to run Nginx as a non-privileged user, the port it's running on needed to change to a non-privileged port (above 1024).

The last build of the old version that exposed port 80 was trafex/alpine-nginx-php7:ba1dd422

Usage

Start the Docker container:

docker run -p 80:8080 trafex/alpine-nginx-php7
