Small Go tool + distroless container used as a K8s initContainer to block an app until its database (Postgres/MySQL) is reachable. Env-var configured (WAITFORDB_* + libpq PG* fallback), configurable timeout/interval, redacted logs, exit codes. Woodpecker CI publishes docker-internal/waitfordb on tag.
