feat: UBI 9 template content (chisel->UBI9 program A2) - #1
Merged
Conversation
Transforms the template from Ubuntu-chiseled (FROM scratch) to UBI 9
(ubi-minimal builder -> ubi-micro runtime): digest-pinned bases, the rpm
database preserved for scanners, and OpenSCAP RHEL9 STIG + Trivy + Grype gates.
Coupled core (edited as one consistent contract; verify.py is the oracle):
- containers/Dockerfile: ubi-minimal builder (dnf --installroot=/rootfs,
keeps /var/lib/rpm + /var/lib/dnf) -> ubi-micro runtime; USER 65532; entrypoint unchanged.
- manifest schema v2: base.{builder,runtime}@sha256 + dnf.packages; drops
chisel/ubuntu_series; optional application.build for from-source FIPS images.
- generate_build_args.py / check_image_manifest.py / verify.py kept in lockstep
(UBI_MINIMAL_IMAGE/UBI_MICRO_IMAGE/DNF_PACKAGES/DNF_REPOS).
- tests/runtime-hardening.sh: forbids shells + dnf/microdnf/rpm/yum/curl/wget;
asserts the rpmdb is present and the UBI CA bundle is populated (symlink-safe);
setuid + world-writable scans; entrypoint parameterized.
- reusable-chisel-image-build.yaml -> reusable-ubi-image-build.yaml (+ ci.yaml).
Release + evidence:
- publish-image.yaml (frozen per-image; cosign keyless SAN unchanged):
cosign sign/verify --recursive; OpenSCAP DISA RHEL9 STIG (SSG v0.1.81 built
from the SHA512-pinned source tarball); Trivy and Grype (--ignore-unfixed,
0 fixable HIGH/CRITICAL); runtime-hardening; anonymous public-pull check.
- check_compliance_checklist.py + docs/compliance/rhel-9-stig-v2r8-applicability.md:
446 DISA RHEL9 STIG V2R8 requirements parsed from the primary XCCDF;
EXPECTED_SOURCE_HASH pinned to the DISA zip.
- renovate: UBI base digests (redhat versioning) + golang <1.26 GOFIPS140 guard.
- template ADRs 0001 (adopt UBI9), 0002 (compliance gate), 0003 (publish-image identity).
`python tools/verify.py ci` green locally across all 14 targets.

…pection The CI image-build self-test caught two real issues; both fixed and re-validated locally with a full `docker buildx` build + runtime-hardening run: - Dockerfile rpm-rootfs: ubi9/ubi-minimal has microdnf, not dnf (the build failed with `dnf: command not found`). Switch to `microdnf install --installroot=/rootfs` with the setopts microdnf requires for an installroot (--config/--noplugins/reposdir/varsdir/cachedir, --nodocs, install_weak_deps=0). Verified it installs ca-certificates (+deps), writes /rootfs/var/lib/rpm/rpmdb.sqlite (38 pkgs scanner-visible), and populates the CA bundle. verify.py dockerfile marker updated to `microdnf install ...`. - tests/runtime-hardening.sh: inspect the `docker export` tar in place (tar -tvf for the manifest + permission scan, tar -xOf for single-file contents) instead of extracting the whole rootfs. Full extraction is unnecessary and not portable (recreating the rootfs symlinks fails off-Linux), while in-place inspection is identical on CI and workstations. rpmdb-present, symlink-safe CA-bundle, setuid, and world-writable checks all preserved.

Program phase A2 — UBI 9 template content
Lands the full Red Hat UBI 9 image-repo template into this repo (created empty at G2), replacing the Ubuntu-chiseled design.
