This runner builds on the host's Docker daemon — the same daemon the live
container runs on — so retagging :latest IS a deployment. Watchtower compares
the running container's image against :latest, sees they differ, and recreates
the container from whatever was just built locally. Gating only the push was
never enough; the build itself was the deploy.
The worse failure is quieter. Reassigning :latest leaves the running
container's old image untagged, and once that image is pruned Watchtower can no
longer read it to compare against:
Failed to retrieve container image info: No such image: sha256:…
Unable to update container: no available image info.
bennett-portfolio hit exactly that. It sat on a four-day-old build, failing to
update 720 times in twenty-four hours, reporting healthy the whole time, and had
to be recreated by hand. This repo has the same workflow and the same exposure —
it simply has not been unlucky yet.
A PR now builds pr-<number>, which nothing watches. Trivy scans whatever was
built either way, so a bad Dockerfile or a new CVE still blocks the merge, and
the push step is unchanged — still main-only.
Run the workflow on pull_request too, so tests + build + Trivy must pass before main can be
merged (branch protection requires this check). Push the image only on a real push to main —
never from a PR. Also standardises the workflow across all apps (three had drifted).
The image build runs 'mvn -DskipTests' and the workflow was only build -> Trivy -> push, so
no app test has ever run in CI — only Trivy gated a merge. The platform contract tests added
in 0.1.9 were not running either, which defeated their purpose.
They cannot run inside 'docker build' — Testcontainers needs a Docker daemon and a build has
none. Maven runs as a sibling container instead, mounting the workspace volume act_runner
gave this job (matched on GITHUB_WORKSPACE, since it is mounted at the full repo path rather
than at /workspace) and sharing the host network so published test ports resolve as localhost.
Verified on itsthevine before rolling out here: 33 tests ran, and a deliberately failing test
failed the run at the Test step with the registry digest unchanged — no image published.
Same site — glass header, bento grid, hero drift, dark mode — with three things fixed
on the way:
- Tailwind and lucide came from CDNs on every page load, and the fonts from Google. All
are now built in or self-hosted, so the site owes nothing to third parties at runtime.
- The hero and bento photographs were hot-linked from Unsplash. They are re-encoded to
webp and served from the MinIO bucket with a year-long cache.
- The ministries and labs were hard-coded in the markup, so launching a ministry meant
editing HTML. They now come from /api/network.
The mobile menu button also opens something now; it did nothing before.
