I created an application on Bluemix and I want to create a private Boilerplate from it in order to automatically deploy them when required through a web interface. Is there any possible way to create that boilerplate?
Boilerplates are not public documented, so not possible to create your own in the catalog.
But you can check "Deploy to Bluemix Button" which perhaps covers your requirement of being able to deploy an app and its runtime and required services.
