# Orchestrator Infra Bootstrap (DEVOPS-ORCH-32-001)

## Components
- Postgres 16 (state/config)
- Mongo 7 (job ledger history)
- NATS 2.10 JetStream (queue/bus)

Compose file: `ops/devops/orchestrator/docker-compose.orchestrator.yml`

## Quick start (offline-friendly)
```bash
# bring up infra
COMPOSE_FILE=ops/devops/orchestrator/docker-compose.orchestrator.yml docker compose up -d

# smoke check and emit connection strings
scripts/orchestrator/smoke.sh
cat out/orchestrator-smoke/readiness.txt
```

Connection strings
- Postgres: `postgres://orch:orchpass@localhost:55432/orchestrator`
- Mongo: `mongodb://localhost:57017`
- NATS: `nats://localhost:4222`

## Observability
- Alerts: `ops/devops/orchestrator/alerts.yaml`
- Grafana dashboard: `ops/devops/orchestrator/grafana/orchestrator-overview.json`
  - Metrics expected: `job_queue_depth`, `job_failures_total`, `lease_extensions_total`, `job_latency_seconds_bucket`.

## CI hook (suggested)
Add a workflow step (or local cron) to run `scripts/orchestrator/smoke.sh` with `SKIP_UP=1` against existing infra and publish the `readiness.txt` artifact for traceability.

## Notes
- Uses fixed ports for determinism; adjust via COMPOSE overrides if needed.
- Data volumes: `orch_pg_data`, `orch_mongo_data` (docker volumes).
- No external downloads beyond base images; pin images to specific tags above.
