Lighttpd and PHP running on Docker Example

Note: 1 of this post’s 7 links are now broken — mostly dead 2008–2013 feed-syndication infrastructure (FeedBurner, Gawker, AOL’s old blog network, Pheedo, Yahoo Pipes). Left as originally published.

Here is a low resource Lighttpd with PHP Docker image running on Alpine Linux, only ~37MB image.

Github = https://github.com/alastairhm/alpine-lighttpd-php
Docker Hub = https://hub.docker.com/r/alastairhm/alpine-lighttpd-php/

Create an example PHP file in your local directory

echo "<?php phpinfo(); ?>" >> index.php

Then start the Docker image;

docker run --name "my-lighttpd-php" -p 8000:80 -v $(pwd):/var/www alastairhm/alpine-lighttpd-php

Browse to http://localhost:8000/

Testing Docker Puppet Module

This module https://github.com/garethr/garethr-docker lets you install and control Docker using Puppet.

For example this Vagrant setup spins up an Ubuntu VM and then using the Docker module spins up a Jenkins build server Docker container with a few simple commands;

include docker
docker::image { 'jenkins': }
docker::run { ‘some-jenkins’:
image => ‘jenkins’,
ports => ‘8080:8080’,
volumes => ‘/vagrant/jenkins’,
use_name => true,
}
