For example, a command such as 11 ``deis scale cmd=10`` tells the scheduler to run ten containers from the 12 Docker image for your app. 13 14 The scheduler must decide which machines are eligible to run these container 15 jobs. Scheduler backends vary in the details of their job allocation policies 16 and whether or not they are resource-aware, among other features. 17 18 The Deis scheduler client is implemented in the :ref:`controller` component. 19 Deis uses `Fleet`_ to schedule the containers across the cluster. 20 21 22 .. _`Fleet`: https://github.com/coreos/fleet
