If you want to enable the new Dispatcher service, you have to run a "sidecar" container (see dispatcher service in docker-compose.yml example) or run a simple container like this:
docker run -d --name librenms_dispatcher \
--env-file $(pwd)/librenms.env \
-e SIDECAR_DISPATCHER=1 \
-e DISPATCHER_NODE_ID=dispatcher1 \
-v librenms:/data \
librenms/librenms:latest
-v librenms:/data
⚠️ librenms
must be a valid volume already attached to a LibreNMS container
