From 8f099c3f8373b9e5e41b75ded5b047e5dbe858e9 Mon Sep 17 00:00:00 2001 From: Devin Foley Date: Tue, 8 Sep 2026 16:56:35 -0700 Subject: [PATCH] ci: dispatch a Docker build for every canary tag (#12950) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Every master merge publishes an npm canary, and downstream managed deployments consume the matching `sha--cloud` Docker image. > - The canary image relies on the master-push `docker.yml` run, whose single pending concurrency slot is superseded by every newer push. > - On a busy day the image build never survives: five consecutive canaries shipped npm packages with no cloud image on 2026-09-06, and downstream deploys starved for ~18 hours while master kept moving. > - The nightly and beta lanes already solve exactly this by dispatching `docker.yml` at their tag ref after pushing it. > - This pull request wires the canary lane into the same mechanism, so every canary tag gets an image build no master push can supersede. > - The benefit is that a published canary always has its images, and downstream release resolution stops walking back to day-old builds during busy merge windows. ## Linked Issues or Issue Description Refs #12769 / #12855 (the earlier image-publishing incident in the same pipeline, different failure mode). **What happened?** `docker.yml` serialises per ref with one pending slot (`concurrency: docker-${{ github.ref }}`, `cancel-in-progress: false`). Master pushes arriving faster than the ~50-minute build supersede the pending build indefinitely. On 2026-09-06, canaries `2026.906.0-canary.1` through `.3` (and the commits between) published to npm with no `sha--cloud` image on GHCR — the Docker run list shows `cancelled, cancelled, cancelled` for their commits. Downstream managed rollouts correctly refused to deploy image-less canaries and pinned at `canary.0` for ~18 hours. **Expected behavior** Every published canary has its Docker images. A busy merge window must not be able to prevent image publication for tagged releases. **Steps to reproduce** 1. Merge to master more often than the Docker build takes to complete, for several hours. 2. Observe npm canaries advancing while every `Docker` run for their commits completes `cancelled`. 3. Observe `ghcr.io/paperclipai/paperclip:sha--cloud` returning 404 for each of those canaries. **Paperclip version or commit** Master at `83987210` (diagnosis time); the starved canaries were `2026.906.0-canary.1`–`.3`. **Deployment mode** GitHub Actions release + image pipeline; consumed by managed cloud deployments. ## What Changed - `.github/workflows/release.yml`, `publish_canary` job: - New step after "Push canary tag": dispatch `docker.yml` at `refs/tags/canary/v` — identical to the nightly and beta lanes' existing step, including the step-summary note. The dispatched run keys its concurrency off the tag ref, so master pushes cannot supersede it, and `docker.yml`'s `type=sha` mapping publishes `sha-` / `sha--cloud` for any ref. - The job gains `actions: write`, mirroring `publish_nightly`. - No `docker.yml` changes: it already accepts `workflow_dispatch` for exactly this pattern. - No dry-run guard needed: `publish_canary` runs only on `push` events, so the `dry_run` dispatch input cannot reach it. ## Verification - YAML lints clean; the step is a line-for-line mirror of the proven nightly-lane step (tag source swapped for the job's existing `canary_tag` output). - The concurrency claim is docker.yml's own documented behavior: groups are per-ref, and a tag ref is distinct from `refs/heads/master`. - Not run: a live canary publish — the next master merge after this lands exercises it end to end; the worst case (double build for a canary whose master-push run also survives) is benign, since both runs push identical content-addressed tags. ## Risks - Low. Roughly one additional Docker build per canary on busy days (on quiet days the master-push run and the dispatched run both execute — duplicate work, identical images, no conflict since the sha tags are content-equivalent for the same commit). - `actions: write` on `publish_canary` matches the grant `publish_nightly` already carries for the same purpose. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR. Feature PRs that overlap with planned core work may need to be redirected — check the roadmap first.
