Deploy a Middleman site by building it server-side on a Git post-receive (making deployment as easy as "git push").

post-receive.sh

#!/bin/sh

# Simply point your virtualhost to the GIT_WORK_TREE below, with "/build" appended. (ex: /path/to/webroot/example.com/build)
# This is how I manage all of my sites. I highly recommend this setup.

GIT_WORK_TREE=/path/to/webroot/example.com # Set this to your webroot path (sans build)
export GIT_WORK_TREE
git checkout -f

# Enter Directory
cd $GIT_WORK_TREE

# Install Gems
bundle install

# Build Middleman
bundle exec middleman build
