Re: Buildpacks PMC - 2015-05-04 Notes

Thanks for the update Mike. Can we get a bit more detail on java-buildpack
divergence from the other buildpacks?

Hi all,

We held the first Buildpacks PMC meeting today; I'd like to share the
agenda and notes.

For reference, all agendas notes for the Buildpacks PMC will be kept in a
public Google Drive folder at this URL:

http://bit.ly/cf-buildpacks-pmc


I realize GDrive isn't the most convenient medium for some in the CF
community; I'd love to hear how we can better support transparency for
everyone.

Please feel free to respond with comments and questions!

Cheers,

Recent Inception Report and Stated Goals

The Buildpacks core development team held a project inception on
2015-04-20, to gain a shared understanding of upcoming goals and tracks of
work.


Goals


- Expand supported ecosystem to include more languages & frameworks
- Cloud Foundry ownership of Buildpacks
- Leverage new primitives in Diego (“app lifecycle”)
- Enable 3rd party extensions to the Developer experience
- Enable application developer extensions to the Developer
experience
- Set patterns for creating new buildpacks and for extending the
Developer experience
- Generate clearer diagnostics during staging
- Enable Operator ease of updating common dependencies
- Keep the `bin/detect` experience: buildpacks should Just Work™
- Exert more ownership over the rootfs
- Binary buildpack support


Risks


- java-buildpack is diverging quickly from the core buildpacks
- Lack of deep experience in some ecosystems
- Wide variety in implementations across buildpacks
- rootfs: with great power comes great responsibility (e.g.,
security response)
- tight coupling between buildpacks and rootfs
- versioning between buildpacks and rootfs


Current Backlog and Priorities

See https://www.pivotaltracker.com/n/projects/1042066

Notable near-term goals:


-

staticfile-buildpack support in `cf-release`
-

binary buildpack (a.k.a. “null buildpack”) support in `cf-release`
-

ability to generate and test CF rootfs-specific binaries; and tooling
for CF operators to do the same



Proposal: Buildpack Incubation Process

Discussion today for PMC input; a draft document will be circulated for
comment to cf-dev@ mailing list after the meeting, in a separate thread.
