### AI overview

The excerpt's production Compose blueprint makes startup readiness, network access, secrets, and resource limits explicit. Long-form `depends_on` gates the API on a TCP health check for Postgres, then on a one-shot migration's successful exit; this avoids startup races and concurrent migration runs when scaling the app. Separate `dmz` and internal backend networks leave only Nginx's port published and isolate the data stores. File-sourced Compose secrets stay out of environment variables and `docker inspect`, though outside Swarm their host file permissions control container access. The blueprint also applies CPU, memory, and process limits, non-root users, read-only filesystems, and dropped capabilities. It notes named-volume compatibility with image ownership, bind-mount ownership pitfalls, Redis cache headroom, and rootless Docker's restriction on publishing ports 80/443. It recommends validating the rendered configuration, service health, migration exit status, network isolation, and applied limits.

### Source excerpt

Eliminate silent startup failures, race conditions, and network exposure in multi-container stacks using Docker Compose v2 health gates and least privilege.
