# Exporter image-mapping test example

Run the exporter in dry-run mode to print the `service -> image:tag` mapping without starting the metrics loop:

```bash
SERVICES_UP_SCRIPT=/workspace/docker/services-up.sh python monitoring/docker-exporter/exporter.py --dry-run
```

Example output excerpt:

```json
{
  "crowdsec": "crowdsecurity/crowdsec:latest",
  "docker-update-exporter": "python:3.11-slim",
  "nextcloud-webapp": "nextcloud:production",
  "node-red": "nodered/node-red:latest",
  "prometheus": "prom/prometheus:latest",
  "traefik": "traefik:3"
}
```

This confirms the exporter now reports images for both:
- services with explicit `image:` values, and
- services using `build:` contexts.
