Deploying a Pedestal application to Bluemix

Create the pedestal app

If you haven't already, create a Pedestal application with Leiningen:

lein new pedestal-service the-next-big-server-side-thing

Make it use VCAP_APP_PORT as the server port

Bluemix apps have to bind to the port provided in the VCAP_APP_PORT environment variable. Otherwise, Bluemix won't know how to talk to the app and will report that the app failed to start.

Edit service.clj and replace

::bootstrap/port 8080})

with

::bootstrap/port (Integer. 
                   (let [port (System/getenv "VCAP_APP_PORT")]
                     (or port "8080") ))})

Add a manifest

Add a manifest.yml file to your project directory:

---
applications:
- name: application-name
  memory: 512M
  host: host-name
  stack: cflinuxfs2
  instances: 1
  path: .
  buildpack: https://github.com/heroku/heroku-buildpack-clojure.git

This tells Bluemix to use a custom buildpack for Clojure and the cflinuxfs2 stack, which gives us Ubuntu 14.04 instead of the default 10.04. Can you believe Bluemix is still using 10.04 by default? That's not even supported anymore!

Login to Bluemix and push the app

Login, push...

cf login
cf push

... and go to host-name.ng.mybluemix.net.
