Admin Utility

Introduction

Purpose of this script is to build a framework which can be leveraged to build utilities to help the on-field ops in system debugging.

Adding custom functions

Refer to the security groups example for reference implementation under, admin/plugins/nsx_v3/resources/securitygroups.py

Adding new functions is fairly straightforward:

  • Define the function under appropriate package. We use neutron callbacks to provide hooks. So your function definition should be like,
::

def function(resource, event, trigger, **kwargs)

  • Add the Resources and Operations enums if they don't exist.
::
class Operations(object):

NEUTRON_CLEAN = 'neutron_clean'

::
nsxv3_resources = {

constants.SECURITY_GROUPS: Resource(constants.SECURITY_GROUPS, ops)

}

  • In resource.py, add the function to the callback registry.
::
registry.subscribe(neutron_clean_security_groups,

Resources.SECURITY_GROUPS.value, Operations.NEUTRON_CLEAN.value)

  • To test, do
::

cd python-nsxadmin/

sudo pip install -e .

nsxadmin -r <resource_name_you_added> -o <operation_you_added>

TODO

  • Use Cliff
  • Auto complete command line args.

Directory Structure
