Host pi
  HostName raspberrypi.local
  User pi

set up the deploy dir on the pi

mkdir -p /home/pi/deploy/pi-time

Make a bare repo on the pi

mkdir -p /home/pi/git-repos/pi-time
cd /home/pi/git-repos/pi-time

git init --bare

vi hooks/post-receive

Put this in the hooks/post-receive:

#!/usr/bin/env bash
 
set -u
set -e

NODE_JS_HOME=/home/pi/node-v0.10.16-linux-arm-pi

PATH=$PATH:$NODE_JS_HOME/bin
export GIT_WORK_TREE="/home/pi/deploy/pi-time"
export NODE_VERSION="0.10"
 
echo "--> Checking out..."
git checkout -f
 
echo "--> Installing libraries..."
cd "$GIT_WORK_TREE"
npm install

echo "--> Stopping app"
node_modules/forever/bin/forever stop led-server.coffee

echo "--> Starting app"
node_modules/forever/bin/forever start -c node_modules/coffee-script/bin/coffee led-server.coffee
 

Make the post-receive hook executable:

chmod +x post-receive

Add the remote on the dev machine

git remote add pi ssh://pi/home/pi/git-repos/pi-time

git remote -v

git push pi master

set up the deploy junk
