Dockerfile is multi-stage:
- build: golang:1.25-bookworm, CGO_ENABLED=0 (modernc.org/sqlite
is pure-Go) + -trimpath + -ldflags "-s -w" so the resulting
binary is small and reproducible-ish.
- runtime: gcr.io/distroless/static:nonroot, ~2 MB. Runs as uid
65532. /data and /var/lib/librenotes are declared volumes so
per-tenant notes and the SQLite database survive container
restarts.
healthcheck subcommand: distroless static has no shell or
wget/curl, so /healthz is reachable but no client to call it. A
new "librenotes healthcheck" subcommand uses net/http to GET
$LIBRENOTES_HEALTHCHECK_URL (default 127.0.0.1:8080/healthz) and
exits non-zero on failure. Both compose files invoke it from the
HEALTHCHECK directive.
httpapi adds a tiny GET /healthz that returns {"status":"ok"}
(no DB ping yet — added when readiness probes need it).
docker-compose.yml: dev stack on :8080 with named volumes and a
LogMailer; everything via env vars, JWT secret defaulted to a
dev value.
docker-compose.prod.yml: layered overrides — pulls a registry
image, expects LIBRENOTES_* env, sets memory limits and JSON-
file log rotation.
Closes #25.
