+With `docker run`
+^^^^^^^^^^^^^^^^^
+Include the `--gpus` flag with the `docker run` command.
+
+**Note:** Make sure the `--gpus` is present before the image name in the command, otherwise it won't work.

+
+    docker run --rm -v /var/run/docker.sock:/var/run/docker.sock:ro --gpus --pid host --network host -it docker.io/nicolargo/glances:latest-full
+
+..

+
+With `docker-compose`
+^^^^^^^^^^^^^^^^^^^^^
