Migrates scanner, scanner-db, and vulnerabilities images from ubi9-minimal to ubi9-micro base, following established patterns from stackrox/stackrox and stackrox/collector repositories. Changes: - Scanner images: Multi-stage build with package_installer for runtime deps - Scanner-DB images: Complex migration with PostgreSQL via chroot user/locale setup - Vulnerabilities image: Simple base image change (minimal deps) - Tekton configs: Added RPM prefetch + ACTIVATION_KEY for hermetic builds - rpms.in.yaml: Scanner packages (excludes coreutils - ubi9-micro has coreutils-single) - rpms.lock.yaml: Generated lockfile for all architectures Benefits: - ~30-35% image size reduction (ubi9-micro ~28MB vs ubi9-minimal ~92MB) - Improved security - package managers removed from runtime - Reduced CVE exposure surface - Alignment with organization-wide ubi9-micro standardization Technical details: - Scanner keeps rpm package (required for image scanning functionality) - PostgreSQL user created as UID/GID 70 via chroot - Locale set to en_US.UTF-8 via chroot - Konflux builds use SHA256-pinned base images - All scripts require bash (not sh) Reference PRs: - stackrox/stackrox#17431 (scanner-db migration) - stackrox/stackrox#17430 (scanner migration) - stackrox/collector#3021 (collector migration pattern) - stackrox/stackrox#19653 (main image migration) - stackrox/stackrox#19985 (debugging utilities) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
