Red Hat Single Sign-On (RH-SSO) is an integrated sign-on solution available as a Red Hat JBoss Middleware for OpenShift containerized image. The {xpaasproduct} image provides an authentication server for users to centrally log in, log out, register, and manage user accounts for web applications, mobile applications, and RESTful web services.
Red Hat offers multiple OpenShift application templates utilizing the {xpaasproduct-shortname} image version number 7.2. These define the resources needed to develop Red Hat Single Sign-On 7.2 server based deployment and can be split into the following two categories:
* Templates using HTTPS and JGroups keystores and a truststore for the RH-SSO server, all prepared beforehand. These secure the TLS communication using link:https://docs.openshift.com/container-platform/latest/architecture/networking/routes.html#passthrough-termination[passthrough TLS termination]:
** *_sso72-https_*: RH-SSO 7.2 backed by internal H2 database on the same pod.
** *_sso72-mysql_*: RH-SSO 7.2 backed by ephemeral MySQL database on a separate pod.
** *_sso72-mysql-persistent_*: RH-SSO 7.2 backed by persistent MySQL database on a separate pod.
** *_sso72-postgresql_*: RH-SSO 7.2 backed by ephemeral PostgreSQL database on a separate pod.
** *_sso72-postgresql-persistent_*: RH-SSO 7.2 backed by persistent PostgreSQL database on a separate pod.

* Templates using OpenShift's internal link:https://docs.openshift.com/container-platform/latest/dev_guide/secrets.html#service-serving-certificate-secrets[service serving x509 certificate secrets] to automatically create the HTTPS keystore used for serving secure content. The JGroups cluster traffic is authenticated using the `AUTH` protocol. The RH-SSO server truststore is also created automatically, containing the */var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt* CA certificate file, which is used to create these cluster certificates. Moreover, the truststore for the RH-SSO server is pre-populated with the all known, trusted CA certificate files found in the Java system path. These are securing the TLS communication using link:https://docs.openshift.com/container-platform/latest/architecture/networking/routes.html#re-encryption-termination[re-encryption TLS termination]:
** *_sso72-x509-https_*: RH-SSO 7.2 with auto-generated HTTPS keystore and RH-SSO truststore, backed by internal H2 database.
** *_sso72-x509-mysql-persistent_*: RH-SSO 7.2 with auto-generated HTTPS keystore and RH-SSO truststore, backed by persistent MySQL database.
** *_sso72-x509-postgresql-persistent_*: RH-SSO 7.2 with auto-generated HTTPS keystore and RH-SSO truststore, backed by persistent PostgreSQL database.
