Create app

$ oc login -u developer
$ oc project myproject


# fork https://github.com/openshift/nodejs-ex
$ git clone https://github.com/openshift/nodejs-ex
$ cd nodejs-ex/
$ hub fork

$ oc new-app -f openshift/templates/nodejs.json -p NAME=luebken-app,SOURCE_REPOSITORY_URL=git@github.com:luebken/nodejs-ex.git

Edit app

# change index.html
$ git add .
$ git commit -m "a commit"
$ git push origin master

# since the local cluster is not reachable from Github we need to start builds manually 
$ oc start-build nodejs-example

Understanding the template

• The nodejs template has the following kubernetes objects: Service, Route, ImageStream, BuildConfig, DeploymentConfig

what about a echo "oc start-build nodejs-example" >.git/hooks/post-commit after you have clone the git repository? This will eliminate the need to manually start a build, but at the same time it will build on each commit...
