Move common ubuntu environment setting to ubuntu-common element The ubuntu, and ubuntu-minimal elements both make use of a common set of environment settings to determine the distribution name. The ubuntu-minimal element also does a few extra things which would appear to apply to both sets and bring in extra architecture support. As such, these are included in the common element. This intends to be part of a series of patches which will eventually create a new element to build a minimal ubuntu-systemd-container element which can be used for lxc/nspawn containers.

ubuntu-common: Update default DIB_RELEASE to bionic The ubuntu-minimal README states that the latest Ubuntu LTS is the default, but currently that is not true. This patch changes the default to the current LTS. Change-Id: I10f28314d1a5969c20094194637cfe31219d228c

Use local mirror for ubuntu-minimal jobs 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

Support secure-boot bootloader where possible As of grub2 >= 2.02-95 on redhat family distros, calling grub2-install on an EFI partition will fail with: "this utility cannot be used for EFI platforms because it does not support UEFI Secure Boot." This version of grub is now in centos8-stream and non-eus repos of RHEL-8. It is not currently possible to build whole-disk UEFI images on these distros, and when this package is promoted this will also affect centos8 and RHEL-8 eus. The grub maintainers made this change because the grub2-install generated /boot/efi/EFI/BOOT/BOOTX64.EFI will never be capable of booting with Secure Boot. This change defines a $EFI_BOOT_DIR for every distro element. When directory /boot/efi/$EFI_BOOT_DIR exists a grub.cfg file in will be generated there. This change also installs the shim package on redhat family distros, which installs a copy of the shim bootloader to /boot/efi/EFI/BOOT/BOOTX64.EFI. Using centos as an example, this allows UEFI to boot the shim /boot/efi/EFI/BOOT/BOOTX64.EFI which then chains to /boot/efi/EFI/centos/grubx64.efi. If /boot/efi/$EFI_BOOT_DIR doesn't exist (such as for Ubuntu, /boot/efi/EFI/ubuntu) the current behaviour of running grub-install to generate /boot/efi/EFI/BOOT/BOOTX64.EFI will continue. For distros such as Ubutnu where packaging does not populate /boot/efi/EFI/ubuntu with .efi files, secure boot can be added in the future by copying .efi files to /boot/efi/EFI/ubuntu and copying the shim file to /boot/efi/EFI/BOOT/BOOTX64.EFI.

Allow disto-specific mirror settings Most of our distros support DIB_DISTRIBUTION_MIRROR for setting the mirror to be used when building. This has a major downside where if someone would like to create a static configuration for building various distro images it cannot set DIB_DISTRIBUTION_MIRROR (think of the case where we want to run our tests). By adding support for DIB_$DISTRO_DISTRIBUTION_MIRROR this problem is resolved. Change-Id: I92964b17ec3e47cf97e3a3091f054b2a205ac768

Use correct Ubuntu distro url on non-x86 arches diskimage-builder usually provides defaults that work out of the box. One default that does not work outside of x86 land is Ubuntu distro mirror url. Considering there are only two valid default options, we can automatically choose a better default. This patch changes behavior only for architectures known to be using http://ports.ubuntu.com/ubuntu-ports. All others still would use http://archive.ubuntu.com/ubuntu as default. It provides some guarantee that we do not introduce a regression. Change-Id: If95a64bac0c88f30736da4bae7f1fdce126c0bf6
