Is anyone currently building or thinking of building a similar tool / vmc
plugin for CF buildpacks?

Thanks for replying James,

We've looked at all the resources you mentioned - this is what made us
think about the need for these private buildpacks.
I would like to better define this notion of 'private' buildpacks:
- 'private' does not necessarily mean a buildpack that is not available
for the Cloud Foundry community to use (not intending to break cloud
- this would mean that the Cloud Controller maintains a list of
buildpacks that it gives to the client for choosing (much like the
framework entity has been used so far)
- it essentially means that the user can choose a buildpack without being
knowledgeable about the buildpack ecosystem and without having to rely on
internal server-side auto-detection

Perhaps the term 'private buildpacks' is not appropriate, maybe something
like 'supported buildpacks' makes more sense.

Is this something covered in the architecture document you mentioned?

Thank you

We're working on an architecture document for buildpacks that we can
share. In the meantime, you can review the dea_ng code and the
cloudfoundry-buildpack-java [1] which uses the Heroku bash hooks for
bin/detect, bin/compile, bin/release as a series of calls that get called
on a buildpack. The ruby/node buildpacks we are testing with are just the
same buildpacks that are posted on the Heroku GitHub account [2] [3].

Is there a plan to have API support for private build packs (build
packs that are hosted inside the CF network)?
If so, the API would need to know about this new entity.
An easy solution would be to keep the framework entity and convert it
to a buildpack on the server-side.

Any pointers?
