Full Description

Convenient Php image with extensions

This image is designed for convenient development. Store PHP configs in your application CVS and mount to a container.
Added commonly used PHP extensions and libraries to official PHP-fpm images.
Small disk size thanks to alpine linux.

Windows Example

mkdir etc
docker run --rm -d -v c:\\www\\etc:/usr/local/etc grikdotnet/php:7.1-fpm-alpine 
... edit configs
docker-compose up


Assuming your document root folder is called wwroot\ and is located in your application folder.

  1. Create a local "etc" folder within your project
  2. Start a container with etc folder mounted, php configs will appear in a mounted folder
  3. Edit php.ini and fpm configs, enable or disable extensions by renaming files in etc/php/conf.d
  4. Restart the php-extensions container
  5. Commit php configs to the project VCS

If you use docker in Linux for development, it is convenient to have the user and group ID inside a docker container synchronized with the user and group ID in your system. Check www-data id in your system, and add yourself to the www-data group.

$ id www-data
uid=82(www-data) gid=82(www-data) groups=82(www-data),82(www-data)
$ sudo usermod -a -G www-data $(whoami)

The value is hard-coded by official image maintainers. It can be changed by extending the image.
