Avi SDK and Utilities

This repository includes API documentation, SDK and sample source to integrate into Avi Solution. Here is brief description of the contents

• doc: Avi API documentation. It includes documentation for the load balancer objects, Analytics Metrics, and Log Analytics APIs.
• python: Source for the python SDK. The pip package can be downloaded from Releases. Here are list of important SDK directories
  • samples: Python samples are in directory python/avi/sdk/samples.
    • autoscale: Gives examples of creating control scripts for server autoscale
    • heat: Provides a heat example for pool servers that can be used with server autoscale feature and control scripts
    • virtualservice_examples_api: provides examples of programmatically creating most common VirtuaServices like basic VS, SSL VS, analytics APIs, tenant based APIs etc.
  • utils: Useful utilities for devops automation.
    • f5_converter: It is utility for converting F5 configuration into AVI configuration
    • httppolicyset_templates: Provides easy to use templates for creating HTTP request and redirect policies for most common use cases
    • Mesos: Provides CRUD apis to create Marathon App with AVI labels

Installation

Pip packages are hosted on GitHub. They can be installed simply as:

Avi SDK Install

$ pip install avisdk

Avi Migration Tools Install - installs F5 and Netscaler to avi conversion tools

$ pip install avimigrationtools

Python Virtual Environment based installation

It is recommended to use virtual env based installation if you are just experimenting with the SDK or F5 converter.

$ apt-get install python-dev python-pip python-virtualenv python-cffi libssl-dev libffi-dev
$ virtualenv avi
$ cd avi
$ source bin/activate
$ pip install avimigrationtools avisdk
$ f5_converter.py -h
$ netscaler_converter.py -h
$ deactivate

Usage

ApiSession Usage

from avi.sdk.avi_api import ApiSession
# create Avi API Session
api = ApiSession.get_session("10.10.10.42", "admin", "something", tenant="admin")

# create virtualservice using pool sample_pool
pool_obj = api.get_object_by_name('pool', 'sample_pool')
pool_ref = api.get_obj_ref(pool_obj)
services_obj = [{'port': 80, 'enable_ssl': False}]
vs_obj = {'name': 'sample_vs', 'ip_address': {'addr': '11.11.11.42', 'type': 'V4'},
         'services': services_obj, 'pool_ref': pool_ref}
resp = api.post('virtualservice', data=vs_obj)

# print list of all virtualservices
resp = api.get('virtualservice')
for vs in resp.json()['results']:
    print vs['name']

# delete virtualservice
resp = api.delete_by_name('virtualservice', 'sample_vs')

If ApiSession is invoked in the context of a control script, then token can be used for authentication. Along with that, information regarding username and tenant information can also be retrieved as follows:

token=os.environ.get('API_TOKEN')
user=os.environ.get('USER')
tenant=os.environ.get('TENANT')
api = ApiSession.get_session("localhost", user, token=token, tenant=tenant)

F5 Converter Usage

See all the F5 converter options

f5_converter.py -h

Convert bigip.conf into Avi configuration. Output is in output directory

f5_converter.py -f bigip.conf
ls output

Netscaler Converter Usage

See all the Netscaler converter options

netscaler_converter.py -h

Convert ns.conf into Avi configuration. Output is in output directory

netscaler_converter.py -f ns.conf
ls output

virtualservice_examples_api Usage

Create a basic virtualservice named basic-vs

virtualservice_examples_api.py -h
virtualservice_examples_api.py -c 10.10.25.42 -i 10.90.64.141 -o create-basic-vs -s 10.90.64.12
