Three things that would not have scaled to 70 roles: - The Python and Ansible dependency pins were about to be copied into every role. They now live once in molecule-shared/, which scenarios reference relatively, so they cannot drift apart. - The helper container images used for probing were hardcoded inline. They are pinned once in molecule-shared/vars.yml, carry `# renovate:` annotations, and a custom manager in .github/renovate.json keeps them current - verified with a local Renovate dry run, which offers curl 8.11.1 -> 8.21.0 and python 3.13 -> 3.14-alpine. Seventy invisible hardcodes is the blindness class we have been removing elsewhere. - Running a scenario meant knowing the venv and cd incantation. `just molecule <role>` does it, and with no argument lists the roles that have a scenario. Molecule is deliberately not wired into prek: a run takes minutes, pulls images and needs Docker, which is fine on request and not fine per commit. docs/molecule-testing.md covers how to run and write these, including the four things a role here needs that a standalone role does not. AGENTS.md points at it rather than carrying the detail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Runs a role's Molecule scenario locally.
|
|
#
|
|
# Called through `just molecule [role] [args...]`. With no role, lists the roles
|
|
# that have a scenario.
|
|
#
|
|
# The same scenarios run in CI (.github/workflows/molecule.yml), but running one
|
|
# here is the faster loop while writing or fixing a role: CI only tells you after
|
|
# a push, and only about the roles that push touched.
|
|
#
|
|
# Deliberately NOT wired into prek. A run takes minutes, pulls container images
|
|
# and needs a working Docker - which is fine when you ask for it, and not fine on
|
|
# every commit.
|
|
#
|
|
# Usage:
|
|
# just molecule # list roles that have a scenario
|
|
# just molecule matrix-alertmanager-receiver
|
|
# just molecule matrix-alertmanager-receiver converge # any molecule subcommand
|
|
#
|
|
# Environment:
|
|
# MOLECULE_DISTRO base image to test on (default: ubuntu2604)
