{project_name} is an integrated sign-on solution available as a Red Hat JBoss Middleware for OpenShift containerized image. The {project_openshift_product_name} 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.
{openshift_name} is available only on *{openshift_image_platforms}*. For other available platforms, see link:{openshift_link_other}[{openshift_name_other}].
=== Comparison: {project_openshift_product_name} Image versus Red Hat Single Sign-On
The {project_openshift_product_name} image version number {project_version} is based on {project_name} {project_version}. There are some important differences in functionality between the {project_openshift_product_name} image and {project_name} that should be considered:
The {project_openshift_product_name} image includes all of the functionality of {project_name}. In addition, the {project_name}-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.
Red Hat offers multiple OpenShift application templates using the {project_openshift_product_name} image version number {project_version}. These templates define the resources needed to develop {project_name} {project_version} server based deployment. The templates can mainly be split into two categories: passthrough templates and reencryption templates. Some other miscellaneous templates also exist.
These templates require that HTTPS, JGroups keystores, and a truststore for the {project_name} server exist beforehand. They secure the TLS communication using passthrough TLS termination.
These templates use OpenShift's internal link:{ocpdocs_serving_x509_secrets_link}[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 and encrypted using the `ASYM_ENCRYPT` protocol. The {project_name} server truststore is also created automatically, containing the */var/run/secrets/kubernetes.io/serviceaccount/service-ca.crt* CA certificate file, which is used to sign the certificate for HTTPS keystore.
Moreover, the truststore for the {project_name} server is pre-populated with the all known, trusted CA certificate files found in the Java system path. These templates secure the TLS communication using re-encryption TLS termination.
* _{project_templates_version}-x509-https_*: {project_name} {project_version} with auto-generated HTTPS keystore and {project_name} truststore, backed by internal H2 database. The `ASYM_ENCRYPT` JGroups protocol is used for encryption of cluster traffic.
* _{project_templates_version}-x509-postgresql-persistent_*: {project_name} {project_version} with auto-generated HTTPS keystore and {project_name} truststore, backed by persistent PostgreSQL database. The `ASYM_ENCRYPT` JGroups protocol is used for encryption of cluster traffic.
For details about OpenShift image version compatibility, see the https://access.redhat.com/articles/2342861[Supported Configurations] page.
NOTE: The {project_openshift_product_name} image version number between 7.0 and 7.3 are deprecated and they will no longer receive updates of image and application templates.
To deploy new applications, use the version 7.4 or {project_version} of the {project_openshift_product_name} image along with the application templates specific to these image versions.
