Three things that all blocked tunnel-start:
1. justfile: dropped set dotenv-load / set export — they pulled
.env.development into every recipe shell, where empty values
beat docker compose --env-file .env per shell-env precedence
(POSTGRES_PASSWORD was the visible casualty). Dev recipes now
pass --env-file .env.development explicitly so they're not
affected by the change.
2. canary image is distroless/static, so the wget-based healthcheck
had no binary to run and every check failed → nginx/tunnel never
started. Added cmd/healthcheck (tiny Go HTTP probe of /healthz),
built alongside canary, swapped compose healthcheck to /healthcheck.
3. Added tunnel-build and tunnel-rebuild recipes so the next person
doesn't have to remember which compose files the tunnel overlay
needs.
Audit F4: compose.yml already passed VITE_TURNSTILE_SITE_KEY as a build arg,
but vite.prod never declared an ARG/ENV for it, so Vite's import.meta.env
resolved to undefined. The Turnstile widget never rendered in prod, causing
the backend to reject every create-token request with TURNSTILE_FAILED.
Production Dockerfile (infra/docker/canary.prod):
- Multi-stage: golang:1.25-alpine builder → distroless/static:nonroot final
- CGO_ENABLED=0, -trimpath, -ldflags='-s -w' → minimal static binary
- Embeds config.yaml; runs as nonroot user
- ENTRYPOINT /canary, CMD -config /config.yaml
- EXPOSE 8080
Development Dockerfile (infra/docker/canary.dev):
- golang:1.25-alpine + air-verse/air for hot reload
- Source bind-mounted by dev.compose.yml; .air.toml drives rebuilds
- go mod download cached at image-build time, dep refresh at runtime if changed
- EXPOSE 8080
Also imports the rest of the template's infra/ that was untracked:
- infra/docker/vite.dev + vite.prod (existing, unchanged)
- infra/nginx/{nginx.conf, dev.nginx, prod.nginx, nginx.prod.conf}
These will be extended in Phase 15 with /api, /c, /k upstream blocks.
