Add ReNo support to manage release notes. http://docs.openstack.org/developer/reno/ We'll start using it during Ocata. Change-Id: Ie8945b6da8c37d5d4e7bc5a09f0d6f75ede9f58f
OpenStackClient reference plugin module
The OSC plugin system is designed so that the plugin need only be
properly installed for OSC to find and use it. It utilizes the
setuptools entry points mechanism to advertise to OSC the
plugin module and supported commands.
tripleoclient is an OpenStackClient (OSC) plugin implementation that implements commands useful for TripleO and the install and management of both an undercloud and an overcloud.
OSC discovers extensions by enumerating the entry points found under
openstack.cli.extension and initializing the given client
oscplugin = oscplugin.plugin
The client module must implement the following interface functions:
API_NAME- A string containing the plugin API name; this is the name of the entry point declaring the plugin client module (
oscplugin = ...in the example above) and the group name for the plugin commands (
openstack.oscplugin.v1 =in the example below)
API_VERSION_OPTION(optional) - If set, the name of the API version attribute; this must be a valid Python identifier and match the destination set in
API_VERSIONS- A dict mapping a version string to the client class
build_option_parser(parser)- Hook to add global options to the parser
make_client(instance)- Hook to create the client object
OSC enumerates the loaded plugins and loads commands from the entry points defined for the API version:
plugin_list = oscplugin.v1.plugin:ListPlugin
plugin_show = oscplugin.v1.plugin:ShowPlugin
Note that OSC defines the group name as
openstack.<api-name>.v<version> so the version
should not contain the leading 'v' character.
This second step is identical to that performed for all but the Identity client in OSC itself. Identity is special due to the authentication requirements. This limits the ability to add additional auth modules to OSC.
The current implementation of the
class is an empty placeholder. This client object is not equired but
OSC's ClientManager will maintain it as required and is the interface
point for other plugins to access anything implemented by this
