| = Bootstrapping a new External Repo Koji build environment = | | = 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 (<code>kojira</code>) is properly configured and running, and at least one Koji builder (<code>kojid</code>) 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 [[Koji/ServerHowTo| ServerHowTo]] .

| * Create a new tag
| | This document has moved to the [https://docs.pagure.org/koji/ Koji Documentation]. The new location is: |
| <pre>
| |
| $ koji add-tag dist-foo
| |
| </pre>
| |
|
| |
|
| * Create a build tag with the desired arches, and the previously created tag as a parent
| | https://docs.pagure.org/koji/external_repo_server_bootstrap/ |
| <pre>
| |
| $ koji add-tag --parent dist-foo --arches "i386 x86_64 ppc ppc64" dist-foo-build
| |
| </pre>
| |
|
| |
|
| * 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.
| | You can submit changes to Koji's docs in [https://pagure.io/koji Pagure] |
| <pre>
| |
| $ koji add-external-repo -t dist-foo-build dist-foo-external-repo http://repo-server.example.com/path/to/repo/for/foo/\$arch/
| |
| </pre>
| |
| * Create a build target that includes the tags you've already created
| |
| <pre>
| |
| $ koji add-target dist-foo dist-foo-build
| |
| </pre>
| |
| | |
| * Create a ''build'' and ''srpm-build'' group associated with your build tag
| |
| <pre>
| |
| $ koji add-group dist-foo-build build
| |
| $ koji add-group dist-foo-build srpm-build
| |
| </pre>
| |
| | |
| * 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 <code>koji list-groups dist-f9-build</code> | |
| against the Fedora Koji instance. This is probably a good starting point for your minimal buildroot and srpm creation buildroot.
| |
| <pre>
| |
| $ koji add-group-pkg dist-foo-build build <pkg1> <pkg2> .....
| |
| </pre>
| |
| | |
| * Add packages that you intend to build to your tag.
| |
| <pre>
| |
| $ koji add-pkg --owner <kojiuser> dist-foo <pkg1> <pkg2> .....
| |
| </pre>
| |
| | |
| | |
| * 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.
| |
| | |
| <pre>
| |
| $ koji regen-repo dist-foo-build
| |
| </pre>
| |
| | |
| = 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-f'''X'''-build'' tags inheriting one another, and ''dist-f'''X'''-updates'' tags and targets that inherit the ''dist-f'''X'''-build'' tag and have external repos attached to them. This way, a ''dist-f'''Y'''-build'' or ''dist-f'''Y'''-updates'' tag will not automatically inherit the external repos of your ''dist-f'''X''''' tags.
| |
| | |
| == Tags ==
| |
| | |
| <pre>
| |
| 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.
| |
| </pre>
| |
| | |
| == Targets ==
| |
| | |
| Each ''dist-f'''X'''-build'' tag has a ''dist-f'''X'''-updates'' child tag, and each ''dist-f'''X'''-updates'' tag has a corresponding ''dist-f'''X'''-updates'' build target.
