• Git
• Java 8
• Spring Boot CLI

• Create a free account on Pivotal Web Services
• install the Cloud Foundry CLI

To follow the simple Spring Boot CLI example:

• in a new file called hi.groovy type:

@RestController class GreetingsRestController { @RequestMapping("/hi/{name}") def hi(@PathVariable String name){ [ greeting : "Hello, "+name+"!" ] } } 

• from the terminal in the same directory as the newly created hi.groovy, run spring jar hi.jar hi.groovy
• you'll be given a .jar that you can execute: java -jar hi.jar

• cf login to ensure that you've authenticated against your Pivotal Web Services account. My session looked like this, yours will feature your own Cloud Foundry credentials.

> cf login API endpoint> api.run.pivotal.io Email> MY_EMAIL@HOST.com Password> Authenticating...

• cf push -p hi.jar SOME_NAME_YOU_MAKEUP_HERE - the SOME_NAME_YOU_MAKEUP_HERE is arbitrary; it'll inform the URL that's used to mount the application and as such it shares a shared global (DNS) namespace
