Perform a number of HTTP GETs on known routes on the devlxd socket API. Minimally all containers must respond to <LXD_SOCKET_API_VERSION>/meta-data when the LXD configuration setting `security.devlxd` is true. When `security.devlxd` is false, no /dev/lxd/socket file exists. This datasource will return False from `is_platform_viable` in that case. Perform a GET of <LXD_SOCKET_API_VERSION>/config` and walk all `user.*` configuration keys, storing all keys and values under a dict key LXD_SOCKET_API_VERSION: config {...}. In the presence of the following optional user config keys, create top level aliases: - user.user-data -> user-data - user.vendor-data -> vendor-data - user.network-config -> network-config :param api_version: LXD API version to operated with. :param metadata_keys: Instance of `MetaDataKeys` indicating what keys to fetch. :return: A dict with the following optional keys: meta-data, user-data, vendor-data, network-config, network_mode, devices. Below <LXD_SOCKET_API_VERSION> is a dict representation of all raw configuration keys and values provided to the container surfaced by the socket under the /1.0/config/ route. r� rh )r� )r� ri r& r& r' ra � s #�ra c C s t �| t�S r< )r Zlist_from_depends� datasources)Zdependsr& r& r' �get_datasource_list� s r� �__main__z*Query LXD metadata and emit a JSON object.)� descriptionrh )N)T)T)G�__doc__Zloggingr~ r= r� r� �enumr r Z json.decoderr �typingr r r r r r r r� Zrequests.adaptersr Zurllib3.connectionr Zurllib3.connectionpoolr Z cloudinitr r r r r Z cloudinit.netr Z getLoggerr@ r! rG rf r� r� rw r( r1 r2 rD rF rO rU ry rV r| r^ r� r� ZResponser� rj r� r� ra ZDEP_FILESYSTEMr� r� �argparser� �ArgumentParser�parser� parse_args�printZ json_dumpsr& r& r& r' �<module> s� $ � � � & c �� �� R�� * � �
