Re: Proposal for supporting the application of multiple buildpacks to a CF app


Dubois, Jan <jan.dubois@...>
 

That is indeed true. All the use cases still assume a single main application process, and therefore a single start command, and owner of $PORT. Any additional processes are meant as helpers inside the container only (either short-lived subprocesses, or long-running sidecars).

If multiple app processes are required, is there a reason not to run them in separate containers?

Cheers,
-Jan

I don't see any consideration in the document for having multiple start commands and picking who gets the default PORT.

Hi All,

The CF Buildpacks team and CAPI team are planning a coordinated effort to introduce support for applying multiple buildpacks during CF application staging. We would like to welcome any and all comments on our proposal[1] from the community before we begin this effort in a few weeks.

A PDF is attached for those who have issues with Google Docs.

Thanks!
