Fabric Orchestrator swagger-client

This is Fabric Orchestrator API

This Python package is automatically generated by the Swagger Codegen project:

• API version: 1.0.1
• Package version: 1.0.0
• Build package: io.swagger.codegen.v3.generators.python.PythonClientCodegen

Generating the Client Code

Due to a BUG in swagger-code-gen, Please follow the steps below

That said, there's a bug in the Python generator of Swagger Codegen 3.x, it doesn't generate the code for Bearer authentication in OpenAPI 3.0 definitions. As a workaround, edit your OpenAPI YAML file and replace this part

  securitySchemes:
    bearerAuth:     
      type: http
      scheme: bearer
      bearerFormat: JWT  

to

  securitySchemes:
    sso_auth:
      type: apiKey
      in: header
      name: Authorization

Then generate a new Python client from the modified API definition.

Requirements.

Python 3.9+

Installation & Usage

pip install

If the python package is hosted on Github, you can install directly from Github

pip install git+https://github.com/fabric-testbed/OrchestratorClient.git

(you may need to run pip with root permission: sudo pip install git+https://github.com/fabric-testbed/OrchestratorClient.git)

Then import the package:

import fabric_cf.orchestrator.swagger_client 

Setuptools

Install via Setuptools.

python setup.py install --user

(or sudo python setup.py install to install the package for all users)

Then import the package:

import fabric_cf.orchestrator.swagger_client

Getting Started

Please follow the installation procedure and then run the following:

from __future__ import print_function
import time
from fabric_cf.orchestrator.swagger_client.api.version_api import VersionApi
from fabric_cf.orchestrator.swagger_client import Configuration, ApiClient
from fabric_cf.orchestrator.swagger_client.rest import ApiException
from pprint import pprint

# Configure API key authorization: bearerAuth
configuration = Configuration()
configuration.api_key['Authorization'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Authorization'] = 'Bearer'

# create_slices an instance of the API class
api_instance = VersionApi(ApiClient(configuration))

try:
    # version
    api_response = api_instance.version_get()
    pprint(api_response)
except ApiException as e:
    print("Exception when calling VersionApi->version_get: %s\n" % e)

Documentation For Orchestrator Proxy

Users are recommended to use Orchestrator Proxy class for any orchestrator operations. Examples are shown below.

Get Resources

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
resources = proxy.resources(token=token)

Create Slice

 import fim.user as fu
 t = fu.ExperimentTopology()
 n1 = t.add_node(name='n1', site='RENC')
 cap = fu.Capacities()
 cap.set_fields(core=4, ram=64, disk=500)
 n1.set_properties(capacities=cap, image_type='qcow2', image_ref='default_centos_8')
 n1.add_component(ctype=fu.ComponentType.SmartNIC, model='ConnectX-6', name='nic1')

 n2 = t.add_node(name='n2', site='RENC')
 n2.set_properties(capacities=cap, image_type='qcow2', image_ref='default_centos_8')
 n2.add_component(ctype=fu.ComponentType.GPU, model='Tesla T4', name='nic2')

 slice_graph = t.serialize()
 sss_key = "<user public key>"
 orchestrator_host = "dev-3.fabric-testbed.net"
 proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
 status, reservation_list = proxy.create(token=token, slice_name=name, slice_graph=slice_graph, ssh_key=ssh_key)

Get Slices

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, slice_list = proxy.slices(token=token)

Get Slice

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, slice_topology = proxy.get_slice(token=token, slice_id=slice_id)

Get Slivers

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, reservation_list = proxy.slivers(token=token, slice_id=slice_id)

Get Sliver

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, reservation = proxy.slivers(token=token, slice_id=slice_id, sliver_id=sliver_id)

Delete Slice by slice_id

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, result = proxy.delete(token=token, slice_id=slice_id)

Delete Slices by email

orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, result = proxy.delete(token=token, email=email)

Renew Slice

now = datetime.now(timezone.utc)
new_time = now + timedelta(days=2)
orchestrator_host = "dev-3.fabric-testbed.net"
proxy = OrchestratorProxy(orchestrator_host=orchestrator_host)
status, reservation = proxy.renew_slice(token=token, slice_id=slice_id,
                                        new_lease_end_time=new_time.strftime('%Y-%m-%d %H:%M:%S %z'))
