Red Hat SummitChapter 1. The Red Hat OpenStack Dashboard service (horizon)
The Red Hat OpenStack Services on OpenShift (RHOSO) Dashboard service (horizon) is a web-based graphical user interface that you can use to manage RHOSO services.
To access the Dashboard in a browser, you must install the Dashboard service, and you must know the Dashboard host name or IP, and login password. The Dashboard URL is:
http://<hostname>/dashboard/-
Replace
<hostname>with the Dashboard host name or IP.
Federation allows users to log in to the OpenStack Dashboard by using Red Hat’s single sign-on (SSO) technology. For more information, see Deploying RHOSO with a single sign-on federated IDP.
By default, users who log out of the OpenStack Dashboard are not logged out of SSO.
