PHP-FPM Docker Image on Alpine
This is a simple PHP-FPM installation running on Alpine Linux. It utilizes the official alpine:3.7 release and installs PHP packages via apk, the Alpine Linux package manager. Please see the Dockerfile for a list of PHP packages installed. The current apk version for PHP is 7.1.14.
This image is created to enhance my own workflow. You are more than welcome to use it, if you are interested. NOTE: the image size reported by the MicroBadger.com badge above is WRONG. The current image size is 108 MB.
To use this image in your own Dockerfiles, add it to your FROM statement:
I have customized the shell by adding
aliases.sh to the
/etc/profile.d directory and enabling the
color_prompt.sh file. Be aware that I prefer
vi keybindings. If you prefer the default
emacs keybindings, type
set -o emacs at the command prompt.
This image is designed to work with my
jkilbride/nginx-alpine. It creates a volume in the
/var/www directory and copies the
info.php file to
nginx image is configured with
/var/www/app/webroot as its document root. To run these two images together, type
docker-compose up -d and point your web browser to
http://[your-docker-host]:8080/info.php. You should see the output of the
For a more interesting example, you can inject your own codebase into the
/var/www/app/webroot directory of this image using a bind mount or a data volume. See the Docker documentation on volumes for more info. This is meant to be a simple example of connecting
alpine, and can be used as the starting point for much more complex environments.
After much trial and error, I have discovered that the
php-debug package for Atom will not listen on the 172.x.x.x network created by
docker-compose. In order to get XDebug working with Atom, I had to supply a different IP address for my debug client in the
xdebug.ini file. Please see the comments in this file to get XDebug working with your client. I am using the Mac OS X native Docker tools. YMMV.

As Alpine Linux uses musl, you may run into some issues with environments expecting glibc-like behaviour (for example, Kubernetes). Some of these issues are documented here:
