How to specify multi buildpack for deployment? #300

Closed myamith closed 5 years ago

myamith commented 5 years ago

In Spring data flow deployment properties can accept only single buildpack. What is the way/support for multibuildpack for example Java-buildpack,python-buildpack.

Questions like this are better suited for StackOverflow or Gitter. Please consider asking in those forums going forward.

That said, the CF-deployer uses the cf-java-client to interact with the Cloud Controller to deploy applications and bind to the desired managed services in the platform. Likewise, SCDF provides an option to deploy Spring Boot uber-jars. And, they are expected to be Java applications.

If you intend to run Python applications via SCDF, you can use the polyglot recipe that we have for K8s. You can, of course, alter it to run it in PCF as well.

Lastly, it'd be great if you can describe the use-cases, so we can relate to why you'd want an application with both Java and Python buildpacks. What is the purpose of this app? Can you share a sample?

Use case is deploy a python app as a task in SCDF and constraint is not to use docker in PCF

Unfortunately, native Python workloads without Docker is not the scope of this project.

Mainly, for Tasks, we track task-execution and transaction statistics, and they are expected to be either the Spring Cloud Task and/or Spring Batch schemas. For native Python workloads, it won't work out-of-the-box, so none of the value-adds would work.

Our primary focus and the value proposition in PAS revolves around Spring Boot applications.
