+Please refer to [Install plugins in the Docker container](https://grafana.com/docs/grafana/next/setup-grafana/installation/docker/#install-plugins-in-the-docker-container). This will install `tdengine-datasource` plugin when Grafana container starts:

+
+1. Save the provisioning configuration file to `tdengine.yml`.

+    - name: TDengine
+      type: tdengine-datasource

+
+2. Write `docker-compose.yml` with [TDengine](https://hub.docker.com/r/tdengine/tdengine) and [Grafana](https://hub.docker.com/r/grafana/grafana) image.
