 # Run container applications on Azure Batch
 
 Azure Batch lets you run and scale large numbers of batch computing jobs on Azure. Batch tasks can run directly on virtual machines (nodes) in a Batch pool, but you can also set up a Batch pool to run tasks in Docker-compatible containers on the nodes. This article shows you how to create a pool of compute nodes that support running container tasks, and then run container tasks on the pool.

 The following C# example assumes that you want to prefetch a TensorFlow image from [Docker Hub](https://hub.docker.com). This example includes a start task that runs in the VM host on the pool nodes. You might run a start task in the host, for example, to mount a file server that can be accessed from the containers.
