SCL

Summary

SCL - Software Collections - are popular packaging format above rpm. Let's enable them for Fedora.

Owner

Current status

  • Targeted release: Fedora 21
  • Last updated: 26. 3. 2014
  • Tracker bug: <will be assigned by the Wrangler>

Detailed Description

My first draft [1] is obsoleted by current state of SCL, Copr... I would keep the SCL workflow simple as possible.

Playground repo

1. Build SCL in Copr

2. Add SCL into Playground repo

Fedora main repo

0. Build SCL in Copr (or use existing SCL)

1. Do standard package review

2. Upload packages into git - specific branch based on Fedora version and name of collection. For stable repo we must be able to replicate builds from git repo, which Fedora own.

3. Build SCL in koji or magically add SCL builds from Copr (depends on preference of releng)

Benefit to Fedora

Cool programs depending on specific version of software can still run on Fedora. We see it often with Ruby (on Rails) projects like Puppet, Cloud projects (Katello, Foreman, OpenShift, OpenStack). All those cool apps can run on any Fedora, which will provide collection for them.

New versions of software can be also packaged as collection and tested it before inclusion into main Fedora repository in case the new version would seem to be to disruptive for rest of the system.

Scope

0. Approve SCL guidelines by FPC

1. Include at least one collection into Fedora Playground repository or into main Fedora repository (probably the one wanted by Cloud WG). It might be this one rebuild for Fedora http://copr.fedoraproject.org/coprs/rhscl/ruby193/. Updates of some gems or addition of other gems might be needed. Review by Cloud projects is needed.

  • Proposal owners: Marcela, ...
  • Other developers: N/A (not a System Wide Change)
  • Release engineering: Magically add SCLs builds into compose or set up koji for SCLs.

Upgrade/compatibility impact

SCL will be safely installed outside of the main system. No conflicts, no updates.

How To Test

0. Install SCL

1. Run your favourite application on the collection

eg. scl enable ruby193 'foreman'
