Add workflow to notify consumers when images publish - #109
Merged
Conversation
Matches the corresponding simplification on the dd-trace-rb side; previewing unmerged images-rb changes is no longer in scope.
…-out Split the single notify job into determine-inputs (unchanged trigger-gating logic) feeding a matrixed notify job, so publishing an image-updated event to additional consumer repos is a matrix entry away. fail-fast: false isolates a failed dispatch to one consumer from blocking delivery to the others. Only DataDog/dd-trace-rb is wired up for now; other consumers (e.g. system-tests) are deliberately not added yet.
Marks system-tests as a known future consumer without wiring it up: no receiver workflow or dd-octo-sts grant exists for it yet.
Keep a single explanatory block above the commented-out entry instead of a duplicated comment above both matrix items.
Replaces the system-tests-specific placeholder with a generic checklist: matrix entry, consumer-side dd-octo-sts policy, cross-repo grant, and a receiver workflow, since all four are prerequisites for any new consumer, not just system-tests.
The comment describes the whole workflow's trigger behavior, not just determine-inputs, so it belongs at the top of the file alongside the manual re-trigger note.
A manual workflow_dispatch can be run against any ref at any time, including a feature branch commit whose Main build hasn't finished publishing an image yet. Query the Actions API for the most recent completed Main run at that commit and fail loudly if it didn't succeed, before notifying any consumer.

This works but is maybe overly complex? |

Summary
Adds
notify-consumers.yml: after a successfulMainbuild onmain, it notifies downstream repos that pin images-rb images (viarepository_dispatch) so they can update their pins. Fans out to a matrix of consumers — currently justdd-trace-rb— and guards against a manual re-trigger racing ahead of the image build.Verification
Reviewed by hand; no automated tests. End-to-end verification is pending the cross-repo dd-octo-sts grant to dd-trace-rb.
