This git repository is a sample Node application to help you get started with using Node on Red Hat's OpenShift PaaS.
The app uses canvas and nodejs to render multi-player pacman and uses socket.io ( http://www.socket.io ) to communicate between the players and viewers ( yeah, you get into viewing mode if its a full house ).
This app is a fork off the original pacman app (great job tjgillies!!) and has changes to use MongoDB in lieu of redis, use specific env variables for OpenShift + a few other improvements to make it a wee bit more resilient. The app is playable on Red Hat's OpenShift PaaS at: http://pacman-ramr.rhcloud.com:8000/
Okay, now onto how can you get this app running on OpenShift.
Create an account at http://openshift.redhat.com/
Create a namespace, if you haven't already do so
rhc domain create -n <yournamespace>
Create a nodejs-0.6 application (you can name it anything via -a)
rhc app create -a pacman -t nodejs-0.6
Add MongoDB support to your application
rhc app cartridge add -a pacman -c mongodb-2.2
Add this github pacman repository
cd pacman
git remote add upstream -m master git://github.com/ramr/pacman.git
git pull -s recursive -X theirs upstream master
Then push the repo to OpenShift
git push
That's it, you can now checkout your application on either of the experimental websocket enabled ports:
http://pacman-$yournamespace.rhcloud.com:8000
OR
https://pacman-$yournamespace.rhcloud.com:8443
Note: If you connect to the standard 80/443 ports ( http[s]://pacman-$yournamespace.rhcloud.com ), the application will fallback to using xhr-polling.
