Heat support in python-openstackclient¶

https://blueprints.launchpad.net/heat/+spec/heat-support-python-openstackclient

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

Problem description¶

python-openstackclient is becoming the default command line client for many OpenStack projects. Heat would benefit from implementing all of its client commands as python-openstackclient plugins implemented in the python-heatclient 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 details can be left to the code reviews for the commands themselves.

The following conventions will be adopted for argument flags:

Commands which trigger lifecycle actions will have a –wait argument which polls the event list until the stack COMPLETE/FAILED event is emitted.
Single character flags will be avoided as per the openstack convention, except for very common arguments such as --template -t, --environment -e
When the stack 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 stack 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.

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

Core stack commands¶

heat stack-create

heat event-show
openstack stack event show

Software config commands¶

heat config-create
openstack software config create

heat config-delete
openstack software config delete

heat config-show

Misc commands¶

heat build-info
openstack orchestration build-info

heat service-list
openstack service list (need to integrate with existing command)

Alternatives¶

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

Implementation¶

Assignee(s)¶

There are many commands to implement and implementation tasks would be easily shared among many developers. The launchpad blueprint whiteboard will be used to coordinate the implementation status of each command and who has assigned themself to implement each one.

Primary assignee:: Steve Baker <sbaker@redhat.com>
Other asignees:: Bryan Jones <jonesbr@us.ibm.com>

Milestones¶

Target Milestone for completion:: mitaka-3

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.

Dependencies¶

None, this is an independent piece of work
