# Signals CI/CD & Local Stack (DEVOPS-SIG-26-001)

Artifacts:
- Compose stack: `ops/devops/signals/docker-compose.signals.yml` (Signals API + Mongo + Redis + artifact volume).
- Sample config: `ops/devops/signals/signals.yaml` (mounted into the container at `/app/signals.yaml` if desired).
- Dockerfile: `ops/devops/signals/Dockerfile` (multi-stage build on .NET 10 RC).
- Build/export helper: `scripts/signals/build.sh` (saves image tar to `out/signals/signals-image.tar`).

Quick start (offline-friendly):
```bash
# build image
scripts/signals/build.sh

# run stack
COMPOSE_FILE=ops/devops/signals/docker-compose.signals.yml docker compose up -d

# hit health
curl -s http://localhost:5088/health
```

Configuration (ENV or YAML):
- `Signals__Mongo__ConnectionString` default `mongodb://signals-mongo:27017/signals`
- `Signals__Cache__ConnectionString` default `signals-redis:6379`
- `Signals__Storage__RootPath` default `/data/artifacts`
- Authority disabled by default for local; enable with `Signals__Authority__Enabled=true` and issuer settings.

CI workflow:
- `.gitea/workflows/signals-ci.yml` restores, builds, tests, builds container, and uploads `signals-image.tar` artifact.

Dependencies:
- Mongo 7 (wiredTiger)
- Redis 7 (cache)
- Artifact volume `signals_artifacts` for callgraph blobs.
