node_health¶
Role is used by the node-health validation to verify state of the overcloud compute services and baremetal nodes they are running on.
As the clients contacted require Keystone authentication, the role requires relevant values, such as Keystone endpoint and username, for correct operation. Otherwise it will produce authentication error.
