Docker Compose Dependency Grapher & Auditor.

Simulate and visualize inter-container dependencies (`depends_on`), startup orders, and potential deadlock loops in complex microservice architectures.

## Microservice Orchestration Auditing

When deploying microservices via `docker-compose`, managing the `depends_on` relationships with condition flags like `service_healthy` is critical to prevent cascading boot failures where application nodes crash before their database dependencies are ready to accept connections.

### FAQ

**Q: Does depends_on wait for the application to be 'ready'?**
A: By default, no. It only waits until the container is running. To wait for application readiness, use `depends_on` with `condition: service_healthy` alongside a defined healthcheck.

**Q: How does this optimize boot time?**
A: By mapping a Dependency Acyclic Graph (DAG), Docker can group independent containers into 'tiers' and boot them concurrently, saving massive amounts of initialization time.
