RealIP only reads XFF when the immediate peer sits in TRUSTED_PROXY_CIDRS,
so an untrusted client can no longer spoof its source IP while a real client
behind a known reverse proxy still resolves correctly. Parses the
comma-separated list via a knadh/koanf ProviderWithValue callback (blank or
whitespace-only input leaves the built-in default intact), wires the var
through both compose files and .env.example, and adds MYSQL_FAKE_* and
TURNSTILE_SECRET env aliases. Covered by config_test.go.
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.
Single project-root compose.yml + dev.compose.yml manage all services.
Production stack (compose.yml):
- nginx public ingress on \${NGINX_HOST_PORT:-22784}:80
- canary Go backend, NO host port (reachable only via nginx)
distroless/static:nonroot Dockerfile
healthcheck → /healthz, depends on postgres + redis
- postgres postgres:18-alpine, no host port, named volume pgdata
- redis redis:7-alpine, no host port, named volume redisdata
- (geolite vol) read-only mount /data for GeoLite2-City.mmdb
Dev stack (dev.compose.yml):
- nginx dev ingress on \${NGINX_HOST_PORT:-58495}:80
- frontend Vite HMR on \${FRONTEND_HOST_PORT:-15723}:5173
- canary Air hot-reload (canary.dev Dockerfile, bind-mounts ./backend)
OTel exports to jaeger:4317
- postgres host port \${POSTGRES_DEV_PORT:-5447}:5432 for psql access
- redis host port \${REDIS_DEV_PORT:-6022}:6379 for redis-cli access
- jaeger UI 16686, OTLP gRPC 4317, OTLP HTTP 4318
- volumes gocache + gomodcache speed up rebuilds
All randomized host ports preserved exactly:
22784 (prod nginx), 58495 (dev nginx), 15723 (vite), 5447 (pg dev),
6022 (redis dev), 16686/4317/4318 (jaeger).
Backend has no host port in production: nginx is the single entrypoint.
Cloudflare Tunnel sidecar terminates at nginx:80 via cloudflared.compose.yml.
backend/compose.yml + backend/dev.compose.yml deleted (merged here).
Validation:
- docker compose -f compose.yml config — OK
- docker compose -f dev.compose.yml config — OK
- docker compose -f compose.yml -f cloudflared.compose.yml config — OK
