This sample app is based on the Pivotal Cloud Node.js Sample App at https://github.com/cloudfoundry-samples/cf-sample-app-nodejs
$ cf push
(See https://docs.cloudfoundry.org/buildpacks/node/node-tips.html)
After that, bind an existing Hazelcast service (e.g.,hcmc1) to the app and restart it.
$ cf bs cf-nodejs hzmc1
