The frontend healthcheck ran 'wget --spider', but the image is distroless: no
shell, no wget, no curl, and node itself is only reachable at an absolute path
(/nodejs/bin/node, off PATH). The probe therefore ENOENT'd on every run, the
container stayed permanently unhealthy, and Traefik -- which will not route to
an unhealthy container -- returned 404 to the customer even though the app was
serving 200 on :3000 the whole time.
Replaced with the Node-exec family using the absolute interpreter path.
Live-verified on the demo box.
Campaign 7 catalog sweep.
