Tacker support in python-openstackclient

Tacker support in python-openstackclient


Implement a new set of tacker commands as python-openstackclient plugins.

Problem description

python-openstackclient is becoming the default command line client for many OpenStack projects. Tacker would benefit from implementing all of its client commands as python-openstackclient plugins implemented in the python-tackerclient repository.

Proposed change

The intent of this spec is to identify the commands to be implemented and establish conventions for command and argument names. This spec is not intented to be a full and correct specification of command and argument names.

The following conventions will be adopted for argument flags:

  • When the name/ID is specified it will be the first positional argument after the full command names
  • When the resource name is specified it will be the second positional argument after the name/ID.
  • show and list commands should show an appropriate quantity of data by default and --short or --long arguments will display a different level of details.

For certain commands which conflict with other OpenStack projects,’nfv’ is prefixed to differentiate the commands. The commands that may conflict include network-service, classifier, nfp, chain and event.

The following tacker commands will be implemented for openstack initially suggesting these command names:

  • Continue to evolve tacker commands and do not implement any openstack commands.
  • Instead of implementing this inside python-tackerclient, create a new project which depends on python-tackerclient and python-openstackclient.

Work Items

Work items or tasks – break the feature up into the things that need to be done to implement it. Those parts might end up being done by different people, but we’re mostly trying to understand the timeline for implementation.
