* `tripleo_overcloud_node_discover_os_cloud`: (String) OS_CLOUD value to use when running the command. If `tripleo_os_cloud` is defined, it will be the default. Otherwise the default is ''. This variable takes precedence over `tripleo_overcloud_node_discover_rc_file`.

stackrc will be used by default.
