Cohesive Networks SDK

Python Cohesive Networks SDK

Cohesive Networks SDK is Python tool providing access to the VNS3 API from applications written in Python. It also includes common pipelines and macro functions for building network topologies.

VNS3 API version: 4.8

Installation

You can PIP install with

pip install cohesivenet

(you may need to run pip with root permission: sudo pip install cohesivenet)

or Install via Setuptools.

python setup.py install --user

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

Usage

Configuring a Client

import cohesivenet
from pprint import pprint

configuration = cohesivenet.Configuration(
    host='https://[vns3-host]:8000',
    username='api',         
    password='YOUR_PASSWORD',
    verify_ssl=False) # Local cert is used by default. Can add your own cert.
# Configure HTTP basic authorization: basicAuth
configuration.username = 'api'
configuration.password = 'YOUR_PASSWORD'
configuration.host = "https://[vns3-host]:8000"
# Create an instance of the API class
vns3_controller = cohesivenet.VNS3Client(configuration)

try:
    api_response = vns3_controller.config.get_config()
    pprint(api_response)
except cohesivenet.ApiException as e:
    print("Exception fetching VNS3 Configuration get_config(): %s\n" % e)

Methods

All endpoints are documented here. Each sub-api is available from the VNS3Client instance as follows:

vns3_client.config                # ConfigurationApi provides VNS3 config methods
vns3_client.bgp                   # BGPApi for Border Gateway Protocol methods
vns3_client.firewall              # FirewallApi for configuring VNS3 policies
vns3_client.high_availability     # HighAvailabilityApi for configuration HA for VNS3
vns3_client.ipsec                 # IPsecApi for IPsec tunnel methods
vns3_client.interfaces            # InterfacesApi for viewing VNS3 interfaces
vns3_client.monitoring            # MonitoringAlertingApi
vns3_client.network_edge_plugins  # NetworkEdgePluginsApi
vns3_client.overlay_network       # OverlayNetworkApi for managing the overlay network
vns3_client.peering               # PeeringApi for peering VNS3 controllers
vns3_client.routing               # RoutingApi for configuring routing
vns3_client.snapshots             # SnapshotsApi for managing backups
vns3_client.sys_admin             # SystemAdministrationApi for access and sys admin tasks
vns3_client.licensing             # LicensingApi for controller licensing 

Common API patterns: cohesivenet.macros

Many API calls are called together to configure a topology or update a network configuration. More macros will be added to increasingly simplify VNS3 topology creation and configuration. More documentation to come.

macros.admin             # Admin operations typically applied to multiple controllers at once
macros.config            # configuring multiple clients
macros.connect           # connecting to clients
macros.ipsec             # ipsec operations like creating a tunnel and then a route
macros.overlay_network   # overlay network functions like calculating network segments of the overlay
macros.peering           # topology peering operations like creating a peering mesh between controllers
macros.routing           # Operations for updating routing in your topology
macros.state             # Methods for fetching the state of your controller(s)

Logging

The SDK can be configured to emit logs for better visibility into what it's doing. The SDK supports INFO, DEBUG, and ERROR logging.

There are two ways to enable it:

1. Set the environment variable COHESIVE_LOG_LEVEL to the value debug, info or error

   $ export COHESIVE_LOG_LEVEL=debug
   

2. Enable it through Python's logging module:

   import logging
   logging.basicConfig()
   logging.getLogger('cohesivenet').setLevel(logging.DEBUG)
