Blue/Green only works when web app is top application in manifest

[brjennin]

Our manifest has a "command runner" application that gets deployed first to run migrations followed by deploying our web application.

Our command runner has no route and is not Blue/Green deployed - there is only one instance of it. Our web server is setup for B/G deploys.

It seems like this gem's B/G deploy route flipping only works if the first application in the manifest is the web application with a route. This may not always be the case (as in our situation). It would be great if it could search the manifest for any application with a color in its name and a route and flip those routes.

Instead of using a command runner app you can just use rake tasks:

require 'cf-deploy'

CF::Deploy.rake_tasks! do
  environment staging: 'assets:precompile'
  environment production: 'assets:precompile'
end

Now when running rake cf:deploy:staging or rake cf:deploy:production the assets:precompile task will be run before hand.

Is there any reason you cannot do this?
