Pipeline ejecutable que orquesta: crear red Docker, pull de imágenes, iniciar Postgres con volume persistente, health check con retry exponencial (pg_isready), e iniciar Metabase conectado via red interna. Configurable con flags: --project, --metabase-port, --pg-user, etc. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

## Notas
|
|
|
|
El pipeline orquesta 5 pasos secuenciales:
|
|
|
|
1. **Red Docker** — crea `{project}-net` con driver bridge
|
|
2. **Pull** — descarga `postgres:16` y `metabase/metabase:latest`
|
|
3. **Postgres** — inicia con volume persistente (named volume por defecto o bind mount con `--pg-volume`)
|
|
4. **Health check** — retry exponencial (hasta ~34 min) con `pg_isready` dentro del contenedor
|
|
5. **Metabase** — conecta a Postgres via red interna, expone en puerto configurable
|
|
|
|
Reutiliza conceptualmente `docker_create_network`, `docker_pull_image`, `docker_run_container`, `docker_inspect_container` y `retry_with_backoff`, reimplementadas inline por ser un ejecutable independiente.

Para destruir el stack:
|
|
```bash
|
|
docker stop analytics-metabase analytics-postgres
|
|
docker rm analytics-metabase analytics-postgres
|
|
docker network rm analytics-net
|
|
```
