Research direction

Start with posit_bakery/config/image/build_os.py, especially OSFamilyEnum and SUPPORTED_OS, then inspect the hardcoded UBI reference in posit-dev/images-package-manager#130. Compare the existing RHEL-family schema with the Containerfile pattern. Done means resolving whether UBI belongs in bakery.yaml as a first-class concept or should remain an implementation detail, with the decision documented.

Description

cvp:0 docker tdp:2

Follow-up from posit-dev/images-shared#575 (RHEL 10 (UBI) image
support).

The bakery OS schema (OSFamilyEnum, SUPPORTED_OS in
posit_bakery/config/image/build_os.py) already models RHEL versions
8/9/10 and sibling distros (Alma, Rocky). It has no concept of "UBI"
anywhere — posit-dev/images-package-manager#130 works around this by
hardcoding registry.access.redhat.com/ubi10/ubi directly in the
Containerfile template rather than expressing it in bakery.yaml.

Question

Is RHEL-family + version sufficient, with "which base image the
Containerfile pulls from" left as an implementation detail (the current
pattern) — or should UBI be a first-class schema concept (e.g. a
baseImage field) before three product repos independently hardcode it?

Notes

Not blocking Phase 1-3 work — package-manager, connect, and workbench
can all follow the existing hardcoded pattern in the meantime.
