This adds "openstack-ci-mirrors" element which performs various settings to get builds using local mirrors. As a first step, we convert ubuntu-minimal jobs The main trick is that since infra mirrors are created with rerepo they are not signed (they are recreated, not cloned, and not signing is seen as a feature in that it deters external use). So we need to instruct debootstrap to ignore signing and also turn it off for in-chroot apt. Other than that, the existing DIB_DISTRIBUTION_MIRROR works to redirect installs. Remove "restricted" as it's not mirrored, and I don't think we want it in here by default. (I think DIB_DISTRIBUTION_MIRROR is a bit of an anti-pattern, because it leaves the mirrors in the final image -- just because you use them to build, doesn't mean you want them at runtime). But we don't need to fix that now, and we don't use any created images.) This pauses fedora testing until the next change, which moves to using local mirrors for testing on fedora/centos Change-Id: I778bd05a1e615c27edf1c9f0a1409119a6b3a850
ubuntu-minimal
The ubuntu-minimal element uses debootstrap for
generating a minimal image. In contrast the ubuntu element
uses the cloud-image as the initial base.
By default this element creates the latest LTS release. The exact
setting can be found in the element's environment.d
directory in the variable DIB_RELEASE. If a different
release of Ubuntu should be created, the variable
DIB_RELEASE can be set appropriately.
