### Breaking changes (26/01/2019)
### Docker Hub repository name change
Since we switched to PHP8 the repository name [trafex/alpine-nginx-php7](https://hub.docker.com/r/trafex/alpine-nginx-php7) didn't make sense anymore.
Because you can't change the name of the repository on Docker Hub I created a new one.

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).
From now on this image can be pulled from Docker Hub under the name [trafex/php-nginx](https://hub.docker.com/r/trafex/php-nginx).

The last build of the old version that exposed port 80 was `trafex/alpine-nginx-php7:ba1dd422`
The old repository will still be available and kept up to date with [trafex/php-nginx](https://hub.docker.com/r/trafex/php-nginx).

## Usage

Start the Docker container:

docker run -p 80:8080 trafex/alpine-nginx-php7
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/alpine-nginx-php7
docker run -p 80:8080 -v ~/my-codebase:/var/www/html trafex/php-nginx

## Configuration
In [config/](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/alpine-nginx-php7
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/php7/conf.d/settings.ini" trafex/alpine-nginx-php7
docker run -v "`pwd`/php-setting.ini:/etc/php7/conf.d/settings.ini" trafex/php-nginx

PHP-FPM configuration:

docker run -v "`pwd`/php-fpm-settings.conf:/etc/php7/php-fpm.d/server.conf" trafex/alpine-nginx-php7
docker run -v "`pwd`/php-fpm-settings.conf:/etc/php7/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_
