If you start creating “layers” in /whatever/ container system, how do you inform the RPM database of what is installed safely? It seems like the deltas in each image would start to cause some file integrity issues with RPM to me. Unless we’re specifically talking about layering without RPM, in which case it’s a non-issue. Just curious. > On Jul 3, 2015, at 2:59 AM, Jan Kurik <jkurik@xxxxxxxxxx> wrote: > > = Proposed System Wide Change: Layered Docker Image Build Service = > https://fedoraproject.org/wiki/Changes/Layered_Docker_Image_Build_Service > > Change owner(s): > * Colin Walters <walters AT redhat DOT com> > * Adam Miller <maxamillion AT gmail DOT com > > * Tomas Tomecek <ttomecek AT redhat DOT com> > * Tim Waugh <twaugh AT redhat DOT com> > > Fedora currently ships a Docker base image, but Docker supports a layering concept.

Currently, we produce two main types of artifacts: RPMs, and images. The RPMs are created in Koji from specfiles in dist-git. The images come in different formats, but have in common creation in Koji from kickstart files — this includes the official Fedora Docker Base Image. This change introduces a new type of image, a Docker Layered Image, which is created from a Dockerfile and builds on top of that base image. > > The system has five major parts: > > * A command-line client — already integrated into rpkg; needs only minor work to enable in fedpkg > * dist-git for Dockerfiles > * A koji plugin, containerbuild > * An OpenShift 3 backend > * A distribution mechanism; initially, this will be > 1. ftp/http mirror (either alt or main mirrors), and > 2. pushed to upstream Docker hub (running our own registry is currently out of scope; see below) > > For more information, see this presentation for the high level overview of the whole system. > > == Scope == > For the Scope of this Change please check https://fedoraproject.org/wiki/Changes/Layered_Docker_Image_Build_Service#Scope > > -- > Jan Kuřík > _______________________________________________ > devel-announce mailing list > devel-announce@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
