+A role to get the deployment status output.
+
+Requirements
+------------
+
+None.
+
+Role Variables
+--------------
+
+* `tripleo_overcloud_status_debug`: (Boolean) Flag to print out the command that is run. Default: False
+* `tripleo_overcloud_status_os_cloud`: (String) (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_status_rc_file`.
+* `tripleo_overcloud_status_plan`: (String) The name of the stakc/plan. Default: overcloud
+* `tripleo_overcloud_status_rc_file`: (String) (String) Path to the credential file to use. If `tripleo_rc_file` is defined, it will be the default. Default: "{{ ansible_env.HOME }}/stackrc"
+
+NOTE: Please note that this command should be run against the undercloud so the
+OS_CLOUD or rc file variables should be set to use the 'undercloud' when
+calling this role. If you are not defining `tripleo_os_cloud` or `tripleo_rc_file`,
+stackrc will be used by default.
+

+* `tripleo_overcloud_status_result`: Ansible shell execution results
+
