Re: [libvirt-jenkins-ci PATCH] guests: allow for container image inheritance

Currently when creating a Dockerfile for a container, we include the full set of base packages, along with the packages for the project itself. If building a Perl binding, this would require us to install the base package, libvirt packages and Perl packages. With the use of the "--inherit libvirt-fedora-30" arg, it is possible to have a dockerfile that only adds the Perl packages, getting everything else from the parent image. For example, a full Dockerfile for libvirt-go would thus be: FROM libvirt-centos-7:latest RUN yum install -y \ golang && \ yum autoremove -y && \ yum clean all -y Note there is no need to set ENV either, as that's inherited from the parent container.
