 heat stack. Depending on environment, the Foundation node could be connected
 to several or to all the internal networks to run necessary tests.
 
-The template 'outputs' should contain the 'foundation_floating' key, for example:
+The template 'outputs' should contain the 'foundation_public_ip' key,
+in case of virtual deploy it will be floating IP, but in case of BM deploy
+we should use management address. Management address will came from
+instance_address attribute of foundation node, according to output of
+FoundationNode.yaml fragment.
+For example:
+For virtual deploys:
 ```
 outputs:
-  foundation_floating:
+  foundation_public_ip:
     description: foundation node IP address (floating) from external network
     value:
       get_attr:

+For Baremetal deploys

+    value:
+      get_attr:
+      - foundation_node
+      - instance_address # Here we will get management IP
