Bootstrapping a new External Repo Koji build environment
These are the steps involved in pointing a new Koji server at
external repositories so that it can be used for building. This assumes
that the Koji hub is up, appropriate authentication methods have been
configured, the Koji repo administration daemon (kojira) is properly configured and running, and at least one Koji builder (kojid) is properly configured and running. All koji cli commands assume that the user is a Koji admin. If you need help with these tasks, see the ServerHowTo .
- Create a new tag
$ koji add-tag dist-foo
- Create a build tag with the desired arches, and the previously created tag as a parent
$ koji add-tag --parent dist-foo --arches "i386 x86_64 ppc ppc64" dist-foo-build
- Add an external repository to your build tag. Koji substitutes
$arch for the arches in your build tag. The "$" needs to be escaped for
the shell to send it though without interpreting it. See below for some
additional examples of external repo URLs.
- NOTE: If you are adding multiple external repos, koji
assigns a priority to each repo in FIFO order. This may cause updated
packages to not be visible if a repo with older packages is ranked at a
higher priority (lower numeric value). Use the
-pflag to set specific repo priorities.
- NOTE: If you are adding multiple external repos, koji

$ koji add-external-repo -t dist-foo-build dist-foo-external-repo http://repo-server.example.com/path/to/repo/for/foo/\$arch/
- Create a build target that includes the tags you've already created
$ koji add-target dist-foo dist-foo-build
- Create a build and srpm-build group associated with your build tag
$ koji add-group dist-foo-build build $ koji add-group dist-foo-build srpm-build
- Populate the build and srpm-build group with packages that will be installed into the minimal buildroot
You can find out what the is in the current groups for Fedora by running koji list-groups dist-f9-build
against the Fedora Koji instance. This is probably a good starting
point for your minimal buildroot and srpm creation buildroot.
$ koji add-group-pkg dist-foo-build build <pkg1> <pkg2> .....
- Add packages that you intend to build to your tag.
$ koji add-pkg --owner <kojiuser> dist-foo <pkg1> <pkg2> .....
- Wait for the repo to regenerate, and you should now be able to run a build successfully.
Regenerating your repo
koji doesn't monitor external repositories for changes. new repositories will be generated when packages you build land in a tag that populates the buildroot or you manually regenerate the repository. you should be sure to regularly regenerate the repositories manually to pick up updates.
$ koji regen-repo dist-foo-build
Examples of urls to use for external Repositories
all these examples use mirrors.kernel.org please find the closest mirror to yourself. Note that the Fedora minimal buildroots download ~100Mb then build dependencies on top. these are downloaded each build you can save alot of network bandwidth by using a local mirror or running through a caching proxy.

Example tags and targets
In the simplest setup, where you just want to build against what is available in the external repositories, you may want to go with a simple layout of dist-fX-build tags inheriting one another, and dist-fX-updates tags and targets that inherit the dist-fX-build tag and have external repos attached to them. This way, a dist-fY-build or dist-fY-updates tag will not automatically inherit the external repos of your dist-fX tags.
Tags
dist-f10-updates - This is where the external repos for f10 release and f10 updates are attached
`- dist-f10-build - This is the f10 build target with the 'build' and 'srpm-build' group inherited from dist-f9-build,
| so that your buildroot gets populated but you do not have to maintain these groups for each
| seperate release.
`- dist-f9-build - etc.
`- dist-f8-build - etc.
Targets
Each dist-fX-build tag has a dist-fX-updates child tag, and each dist-fX-updates tag has a corresponding dist-fX-updates-candidate build target.
