version: 1.1.1

description:
   This app is driven by user input data-model yaml config files.
   It configures IxNetwork using the SDK ixnetwork_restpy python
   package to execute IxNetwork ReST APIs.

Requirements:
   - Runs on Linux OS only.
   - pip install requests, PyYaml
   - data-model yml config file

   Note: This ixNetworkDataModel package comes with ixnetwork_restpy.
         It is inside the /Apps/IxNetworkDataModel/IxNetworkRestpy directory.

   - For port capturing requirements:
      - IxNetwork Wireshark installed
      - Linux OS wireshark installed
      - sudo chmod o+x /usr/bin/dumpcap (For redhat distributions)
      - sudo chmod o+x /usr/sbin/dumpcap (For ubuntu distributions)
   
In your testcase yml files:

   pythonScript: /Modules/IxNetworkDataModel/Scripts/<the_python_script_to_run>.py

   configParametersFile: configs.yml

   importAppLibraryPaths:
      - /Apps/IxNetworkDataModel/src
      - /Apps/IxNetworkDataModel/IxNetworkRestpy
