Modeling of Trunk service in WFO

This is a dummy implementation of a trunk service in workflow orchestrator. The "pieces" of the trunk service are mapped to Products. The parameters of the trunk service are modelled as Resource Types.

Quickstart

  • Follow Steps 1 and 2 from here: https://workfloworchestrator.org/orchestrator-core/workshops/beginner/debian/
  • To install the orchestrator GUI, you can follow the steps 5 and 6 from the above link.
  • Clone this repo:
  • pip install -r requirements.txt
  • from the top-level directory:
  • pip install -e .
  • Create oss-params.json
  • Export the oss-params file: export OSS_PARAMS_FILENAME="/path/to/file.json"
  • The core of workflow orchestrator can be started with uvicorn --host 0.0.0.0 --port 8080 main:app from inside the geant_service_orchestrator directory of this repo.
  • The GUI can be started with yarn start.

Useful WFO Resources

API examples

Note: update IP address in the request to your own where you're running WFO.

Creating subscriptions (look at initial_input_form_generator method of the workflow to find what properties need to be passed in the data of the POST request)

Create process that produces a new subscription (CREATE workflow)

curl -X POST -H "Content-Type: application/json" http://10.98.1.62:8080/api/processes/create_trunk --data '[{"product": "321045fc-21ec-476b-b67b-5f211e47c3d7"},{"trunk_name": "mytrunkfromapi", "geant_s_sid": "a1b2c3"}]'

Create process that manipulates the state of a subscription (TERMINATE workflow)

curl -X POST -H "Content-Type: application/json" http://10.98.1.62:8080/api/processes/terminate_trunk --data '[{"subscription_id": "910e7044-c427-46d1-afc3-7817e221d45d"}, {"are_you_sure": "yes"}]'

Deleting subscriptions (not the same as running a TERMINATE workflow for a subscription, but to actually erase it from the WFO database)

Delete a subscription:

curl -X 'DELETE' 'http://10.98.1.62:8080/api/subscriptions/3f16532b-0a48-4fe3-802a-36b3f54eed0e'

To do the above, you first have to delete the processes first:

curl -X 'DELETE' 'http://10.98.1.62:8080/api/processes/7447a3e9-7c58-4ae7-8804-c0a75c39c924'
