+⚠️  ATTENTION: ${path} is not a persistent mount.
+
+    Your data in this directory may not persist across container restarts or
+    upgrades. To ensure your settings and history are saved, you must mount
+    this directory as a persistent volume.
+
+    Fix: mount ${path} explicitly as a bind mount or a named volume:
+        # Bind mount
+        --mount type=bind,src=/path/on/host,dst=${path}
+
+        # Named volume
+        --mount type=volume,src=netalertx-data,dst=${path}
+
+    Apply one of these mount options and restart the container.
