### Background

I've recently become acquainted with Pivotal Web Services (PWS) - or more specifically, Pivotal Cloud Foundry (PCF). I've racked up quite a monthly bill running a few apps on Heroku with SSL. It's been worth it - its JTBD is DevOps - and I'm willing to pay for it. Pivotal Web Services is a hosted version of the open source Cloud Foundry platform, and is provides similar PaaS functionality.

This post documents some of the resources I read getting a Rails and Ember application running with PostGIS, in the cloud.

### Learning the Ropes

PCF has a command line tool, `cf`, which is similar to Heroku's `heroku`. `cf push` pushes the current working folder to a location that is specified in a `manifest.yml` file.

### Gotchas

Heroku's buildpack outlines a few things, including a postInstall script in package.json that calls /bin/heroku_install.  Turns out, Heroku doesn't really require it, but PCF did.

I also ran into an issue around Heroku's Multi Buildpack and discovered while it currently does work in PCF, a change has been made that has yet to be deployed, and the change will break the Multi Buildpack that I'm currently using.  A workaround for my very-specific `ember-cli-rails` issue is TBD.

#### Notes

When deploying a worker, make sure manifest.yml has:

`no-route: true` and `set-health-check: none`

#### Note: Disable Health Check for a Worker Application

`cf set-health-check app-name none`
