Java on Engine Yard's cloud
Raw
gistfile1.md

EXPERIMENTAL AND UNOFFICIAL, don't expect support of any type from Engine Yard on this. This is just a crazy idea that came to my mind a few weeks ago.

Application configuration

  1. Compile the java web application and create an "exploded" war file with any tool you like better, if you use maven you can run "mvn war:exploded".
  2. Create a git repository for your exploded web application and push the compiled code.
  3. Add those files to the root of your repository:
  4. Go to Engine Yard AppCloud's dashboard and press the button "Create New Application", add the git url for your repository, select "Rack" as application type and submit the form.
  5. Select "Trinidad" as server stack for your new environment.
  6. Create your cluster in the next step, boot it and wait for the deploy to finish!

Database configuration

If you use an embedded database like HSQL you can skip this, your application should be already running.

If you want to use AppCloud's provided database (LIKELY) and you use Spring Framework, you can take advantage of this extension to be able to configure your datasource using the auto generated AppCloud's credentials:

Known issues

  • If the application registers components to the server's level, like JMX beans, the server can not redeploy it properly using the hot deploy because it tries to register the component for the new application when it's still registered by the old one.
