Typesafe activator , play framework applications deployed to Pivotal Cloud Foundry

I decided to quickly build an application using Typesafe activator for a play framework scala application and deploy it to Pivotal Cloud Foundry. You can read more about Typesafe activator below.

https://typesafe.com/activator

Here are the steps to deploy a scala play framework application created using Typesafe activator. I created a basic hello world scala application with the play framework. The purpose here is what is needed to get it deployed on Pivotal Cloud Foundry.

Note: Assumes we have created an application with name "hello-play-scala" and we are in that actually directly as we create files for deployment.

1. Create a distribution ZIP file as follows once you have finished developing your application

> ./activator dist

2. Create a manifest file as follows which refers to the DIST zip file created in #1 above.

applications:
- name: pas-helloworld-scala
  memory: 756M
  instances: 1
  host: pas-helloworld-scala
  domain: apj.fe.pivotal.io
  path: ./target/universal/hello-play-scala-1.0-SNAPSHOT.zip

3. Create a build.sh file, make it executable. This simple shell script is going to call sbt/activator

java -jar activator-launch-1.2.12.jar dist

4. Deploy as shown below.
