What?

This is the “magic” that makes TAS such a compelling product.

Cloud Foundry applications are deployed by cf push-ing your code or some compiled artifact. The appropriate buildpack is identified by the buildpack detect scripts, a staging container is created to prepare your app’s environment, and a droplet is produced. This droplet will be used by the cells to run your application instances. When you push an app, you can optionally include an application manifest.yml that contains properties about your application’s deployment.

How?

  1. Clone the cloudfoundry/cf-acceptance-tests repo to your local workstation.
  2. cd ./cf-acceptance-tests/assets/dora
  3. Create a manifest.yml file
  4. In the manifest.yml, set “dora” as the app’s name
  5. In the manifest.yml, set the disk quota to 1024M
  6. In the manifest.yml, set the number of instances to 2
  7. In the manifest.yml, generate a unique route for your app the first time you push.
  8. cf push your app

Expected Result

cf app dora will print the app’s status, including the URL. When your visit the URL in your browser you should see the words “Hi, I’m Dora!”
