Chapter 2. Before You Begin
2.1. Comparison: RH-SSO for OpenShift Image and Red Hat Single Sign-On
The RH-SSO for OpenShift image version number 7.2 is based on Red Hat Single Sign-On 7.2. There are some differences in functionality between the RH-SSO for OpenShift image and Red Hat Single Sign-On:
- The RH-SSO for OpenShift image includes all of the functionality of Red Hat Single Sign-On. In addition, the RH-SSO-enabled JBoss EAP image automatically handles OpenID Connect or SAML client registration and configuration for .war deployments that contain <auth-method>KEYCLOAK</auth-method> or <auth-method>KEYCLOAK-SAML</auth-method> in their respective web.xml files.
2.2. Version Compatibility and Support
See the xPaaS part of the OpenShift and Atomic Platform Tested Integrations page for details about OpenShift image version compatibility.
2.3. Deprecated Image Streams and Application Templates for RH-SSO for OpenShift
The RH-SSO for OpenShift image version number 7.0 and 7.1 are deprecated and they will no longer receive updates of image and application templates.
To deploy new applications, it is recommended to use the version 7.2 of the RH-SSO for OpenShift image along with the application templates specific to that version.
2.4. Initial Setup
The Tutorials in this guide follow on from and assume an OpenShift instance similar to that created in the OpenShift Primer.
