Jobs Configuration

The jobs configuration should set the following properties within the tasks array which should have a task definition containing:

• docker_image should be the name of the Docker image for this container invocation, e.g., caffe2ai/caffe2:c2v0.8.1.cpu.full.ubuntu14.04
• resource_files array should be populated if you want Azure Batch to handle the download of the training file from the web endpoint:
  • file_path is the local file path which should be set to mnist.py
  • blob_source is the remote URL of the file to retrieve: https://raw.githubusercontent.com/Azure/batch-shipyard/master/recipes/Caffe2-CPU/scripts/mnist.py
