Introduce "base" variant of SLE-Micro-for-Rancher #1050
Conversation
This defines the "base" packages required to run Kubernetes (k3s or rke2) with a minimal number of packages. Esp. missing is "kernel-firmware-all" which drags in 350MB in packages. All other SLE Micro for Rancher variants should be derived from "base". Signed-off-by: Klaus Kämpf <kkaempf@suse.de>

JFYI here we explicitly require elemental package and hence OBS includes this package as part of the buildenv. Then there is the replace_using_package_version OBS buildtime service that finds this package, gets the version of it and replaces a given placeholder with the computed version.
Just something to keep in mind for our own derivatives, we used to compute the tag from elemental package version. We could also compute that version|tag from github tags if the sources are pulled from github. This mostly relates to the images we want to build in OBS.

In former iso images in OBS this %VERSION% is a placeholder to be replaced with the version computed from github sources, more specific form the elemental.obsinfo file. For that the _service file requires an obs_scm service and replace_with_package_version service. Something like:
<service name="obs_scm">
<param name="url">https://github.com/rancher/elemental</param>
<param name="scm">git</param>
<param name="include">.obs</param>
<param name="extract">.obs/dockerfile/slem4r-base-iso/Dockerfile</param>
<param name="revision">main</param>
<param name="filename">elemental</param>
<param name="versionformat">@PARENT_TAG@+git%cd.%h</param>
<param name="versionrewrite-pattern">v([^-]+)-?.*(\+git.*)</param>
<param name="versionrewrite-replacement">\1\2</param>
</service>
<service name="replace_using_package_version" mode="buildtime">
<param name="file">Dockerfile</param>
<param name="regex">%VERSION%</param>
<param name="package">elemental</param>
<param name="parse-version">patch</param>
</service>There was a problem hiding this comment.
Yes, this will be part of the package submission in OBS

Merging as-is, it doesn't influence any other builds. |
This defines the "base" packages required to run Kubernetes (k3s or rke2) with a minimal number of packages.
Esp. missing is "kernel-firmware-all" which drags in 350MB in packages.
All other SLE Micro for Rancher variants should be derived from "base" and
serve as examples of how to build derived images.
