Docker PHP-FPM 7.3 & Nginx 1.16 on Alpine Linux

Example PHP-FPM 7.3 & Nginx 1.16 setup for Docker, build on Alpine Linux. The image is only +/- 35MB large.

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

• Built on the lightweight and secure Alpine Linux distribution
• Very small Docker image size (+/-35MB)
• Uses PHP 7.3 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 to your needs

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).

Usage

Start the Docker container:

docker run -p 80:8080 wuxyyin/docker-php-nginx:tagname

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:/app wuxyyin/docker-php-nginx:tagname

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" wuxyyin/docker-php-nginx:tagname

PHP configuration:

docker run -v "`pwd`/php-setting.ini:/etc/php7/conf.d/settings.ini" wuxyyin/docker-php-nginx:tagname

PHP-FPM configuration:

docker run -v "`pwd`/php-fpm-settings.conf:/etc/php7/php-fpm.d/server.conf" wuxyyin/docker-php-nginx:tagname

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