Application Code SHOULD Be SIMPLE

$ minishift profile set 'devnation-demo'
$ minishift config set cpus 2
$ minishift config set vm-driver virtualbox
$ minishift config set memory 4GB
$ minishift start
$ eval (minishift oc-env) # fish shell!
$ oc new-project devnation

Demo

Set up minishift

$ mkdir myapp && cd myapp
$ npm install -g express-generator
$ express .
$ code-insiders package.json # "PORT=8080 node ./bin/www"
$ npx nodeshift --strictSSL=false --expose

Demo

Create and Deploy an App
