From 11c35ff2be94a0c3f29ec436e7ad3a9366f46d06 Mon Sep 17 00:00:00 2001 From: Tomasz Janiszewski Date: Mon, 13 Apr 2026 12:38:39 +0200 Subject: [PATCH 1/5] build: Migrate scanner standard Dockerfile to ubi-micro Migrates scanner image from ubi9-minimal to ubi9-micro base using proven multi-stage build pattern. Changes: - Remove ARG variables for base images (use explicit registry paths) - Add ubi-micro-base stage from registry.access.redhat.com/ubi9/ubi-micro - Add package_installer stage that preserves ubi-micro RPM database - Install ca-certificates to /out/ with --installroot - Copy package_installer /out/ to final stage - Keep all file operations in final stage (minimal diff) - Retain all original comments Why: ubi-micro eliminates package managers (dnf, rpm tools) reducing image size by ~30-35% and lowering CVE exposure. Pattern follows successful main image migration (PR #19653). Keeps diff minimal by only moving RPM installation to package_installer stage. Expected impact: Scanner image size reduction from ~90MB to ~60MB base. AI-assisted migration based on PR stackrox/stackrox#17430 and #19653 patterns.

Changes: - Add ubi-micro-base stage (SHA256: 093a704be0ea...) - Add package_installer stage (SHA256: 6ed9f6f637fe...) - Install ca-certificates AND openssl (documented in rpms.in.yaml) - Use --setopt=install_weak_deps=0 (standardized numeric syntax) - Use --setopt=reposdir=/etc/yum.repos.d for hermetic builds - Copy package_installer /out/ to final stage - Keep all file operations in final stage (minimal diff) - Retain all original comments (labels, mapping files, etc.) Why: Achieves ~30-35% image size reduction while maintaining FIPS compliance for Red Hat builds.

Changes: .tekton/scanner-v4-build.yaml: - Update prefetch-input to include both gomod and rpm types - Use multi-line YAML format consistent with operator-build.yaml - Enables Cachi2 to prefetch ca-certificates and openssl RPMs rpms.in.yaml: - Update comment to document scanner usage of ca-certificates and openssl - Clarifies which Dockerfiles require these packages Why: ubi-micro cannot run package managers at build time, so RPM packages must be prefetched by Konflux/Cachi2 for hermetic builds. The --setopt=reposdir=/etc/yum.repos.d flag in konflux.Dockerfile references these prefetched packages. Without rpm prefetch, the Konflux build would fail when trying to install ca-certificates and openssl. Follows the pattern used by operator and other Konflux builds.
