Koji containerbuild

This package extends Koji buildsystem with plugin which allows building containers via OpenShift buildsystem. Additionally it provides CLI tool to submit builds based on koji CLI.

Most likely you'll need to run own OpenShift instance. See OpenShift documentation how to setup that.

Build a package

To build the current release, use the following command in the repo directory:

tito build --rpm

Create release tarball

To create tarball for a release run:

python setup.py sdist

Create new release

Create upstream release

In this upstream repository:

  1. Bump release and commit changelog:

    • If this is downstream update, run:

      tito tag
      
    • If this is upstream update you need to specify version. It needs to be without release part, only dot separated one (for example 0.5.7):

      tito tag --use-version 0.5.7
      
  2. See last line of tito output which give you a hint how to push commit and tag to remote (for example 0.5.7-1):

    git push origin
    git push origin koji-containerbuild-0.5.7-1
    
  3. Create srpm:

    tito build --srpm
    

Update downstream release

Following steps are for updating packages in Fedora:

  1. Clone or pull latest changes in downstream repository:

    fedpkg co koji-containerbuild
    
  2. Switch to branch which you want to update (e.g. start with master):

    fedpkg switch-branch master
    
  3. Import srpm created in previos section (for example koji-containerbuild version 0.5.7-1, updating Fedora 24):

    fedpkg import /tmp/tito/koji-containerbuild-0.5.7-1.f24.src.rpm
    
Review changes - there should be single new tarball, entries in changelog looks fine (e.g. not empty).
  1. Try to build package as scratch-build:

    fedpkg scratch-build --srpm
    
  2. If build succeeded commit changes to remote and build regular build:

    fedpkg push
    fedpkg build
    

Update other branches either by merging (preferred) or importing srpm.

Plugin installation

Koji hub

If you already use any Koji hub plugin you need to use same path for this plugin too. Default path used by Koji hub is /usr/lib/koji-hub-plugins.

Modify /etc/koji-hub.conf:

  • set PluginPath to a directory which contains hub_containerbuild.py from this package.
  • add hub_containerbuild value to Plugins. If you have already some plugin enabled use space as a separator between names.

Finally (graceful) restart httpd daemon.

Koji builder

The Koji builder plugin requires the osbs-client package. In Fedora it is part of the official repositories. Additionally you'll need to modify /etc/osbs.conf with the addresses to your OpenShift buildystem instance and registry. Follow the osbs documentation.

Similarly to Koji hub you'll need to find out which path will be used for plugins. Default path used by Koji builder is /usr/lib/koji-builder-plugins.

  • set PluginPath to a directory which contains builder_containerbuild.py from this package.
  • add builder_containerbuild value to Plugins. Similarly to Koji hub use space to separate existing plugin names.

Koji CLI

Package provides CLI binary with interface similar to upstream koji CLI. It adds only single new command - container-build which allows submitting container builds to Koji hub. To configure CLI you'll need to copy [koji] section in /etc/koji.conf to [koji-containerbuild] and optionally adapt configuration there.

Post Install Configuration

As the kojiadmin, add builder(s) to the newly created channel and add a package

$ koji add-host-to-channel --new kojibuilder1 container
$ koji add-pkg --owner some_koji_user some_koji_target testing
