+# 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.
