The runtime image pins lived in meta/distros.yml, which neither the docker updater, the image mirror nor the vulnerability scan reads, so a pin would only ever move by hand. The new role sys-os carries them in its meta/services.yml under the distro id; utils/distros.py renders the workspace matrix from there with the stdlib block reader, and meta/distros.yml keeps the distro attributes only. A new release now arrives as an updater pull request. follow: latest holds debian, ubuntu and fedora to the release their latest tag points at, by Docker Hub digest: Ubuntu moves between LTS releases only (26.10 shares the digest of rolling, not latest) and Fedora skips rawhide (46 shares the digest of rawhide, latest is 45). Arch stays rolling; CentOS stream tags carry no number the updater can order. dockerhub_repo and is_dockerhub move to utils/docker/image/ref.py beside split_registry_and_name, so utils/update/follow.py can use them without an import cycle and utils/update/docker.py stays under the size cap.

Shared Utilities (utils/)
This directory contains shared Python helpers used by custom modules and plugins.
Purpose
Use utils/ for reusable code that should not be duplicated across:
library/modules,plugins/action/,plugins/filter/,plugins/lookup/.
Typical shared utilities:
- API clients,
- validation/conversion helpers,
- path and configuration helpers,
- cross-plugin/module domain logic.
- Shared HTTP(S) connection handler for multiple modules.
- Common validation or transformation functions for user input.
- Utility functions for interacting with Docker, LDAP, etc.
- Grouped helper packages such as
utils/domains/for related domain logic.
Design Guidelines
- Keep helpers focused and composable.
- Avoid side effects during import.
- Prefer explicit function/class APIs over implicit globals.
- Keep dependencies minimal so modules/plugins stay lightweight.
Example Import
from utils.domains.primary_domain import get_primary_domain
What Does Not Belong Here
- Standalone executable modules (put in
library/). - Ansible plugin entrypoints (put in
plugins/*).
