Jan Lieskovsky 88a8c657af [KEYCLOAK-13207] Derive the value of the JBOSS_IMAGE_NAME information 
environment variable from the image stream name instead of using a
hardcoded value

Derive the value of the JBOSS_IMAGE_VERSION information environment
variable from the "project_versionDoc" attribute instead of using
a hardcoded value, since the current "project_versionDoc" value matches
the "7.4" value currently present in the images

Drop the "JBOSS_IMAGE_RELEASE" and "STI_BUILDER" information environment
variables, since they aren't present in the latest version(s) of the
OpenJDK / OpenJ9 images any more

Add raw GitHub locations of the OpenJDK and OpenJ9 RH-SSO 7.4 templates
to be ignored by the tests (currently there are just RH-SSO 7.3 and
RH-SSO CD versions of these)

=== Artifact Repository Mirrors
// This page describes MAVEN_MIRROR_URL variable usage
// It requires 'bcname' attribute to be set to the name of the product
A repository in Maven holds build artifacts and dependencies of various types
(all the project jars, library jar, plugins or any other project specific
artifacts). It also specifies locations from where to download artifacts from,
while performing the S2I build. Besides using central repositories, it is a
common practice for organizations to deploy a local custom repository (mirror).
Benefits of using a mirror are:
* Availability of a synchronized mirror, which is geographically closer and
faster.
* Ability to have greater control over the repository content.
* Possibility to share artifacts across different teams (developers, CI),
without the need to rely on public servers and repositories.
* Improved build times.
Often, a repository manager can serve as local cache to a mirror. Assuming that
the repository manager is already deployed and reachable externally at
*_pass:[http://10.0.0.1:8080/repository/internal/]_*, the S2I build can then use this
manager by supplying the `MAVEN_MIRROR_URL` environment variable to the
build configuration of the application as follows:
. Identify the name of the build configuration to apply `MAVEN_MIRROR_URL`
variable against:
+
[source,bash,subs="attributes+,macros+"]
----
$ oc get bc -o name
buildconfig/sso
----
. Update build configuration of `sso` with a `MAVEN_MIRROR_URL` environment variable
+
[source,bash,subs="attributes+,macros+"]
----
$ oc set env bc/sso \
-e MAVEN_MIRROR_URL="http://10.0.0.1:8080/repository/internal/"
buildconfig "sso" updated
----
. Verify the setting
+
[source,bash,subs="attributes+,macros+"]
----
$ oc set env bc/sso --list
# buildconfigs sso
MAVEN_MIRROR_URL=http://10.0.0.1:8080/repository/internal/
----
. Schedule new build of the application
NOTE: During application build, you will notice that Maven dependencies are
pulled from the repository manager, instead of the default public repositories.
Also, after the build is finished, you will see that the mirror is filled with
all the dependencies that were retrieved and used during the build.

[[conf_env_vars]]
.Configuration Environment Variables
[cols="3",options="header"]
|===
|Variable Name |Description |Example Value
|*_AB_JOLOKIA_AUTH_OPENSHIFT_*
|Switch on client authentication for OpenShift TLS communication. The value of
this parameter can be a relative distinguished name which must be contained in
a presented client's certificate. Enabling this parameter will automatically
switch Jolokia into https communication mode. The default CA cert is set to
`/var/run/secrets/kubernetes.io/serviceaccount/ca.crt`.
|*_true_*
|*_AB_JOLOKIA_CONFIG_*
|If set uses this file (including path) as Jolokia JVM agent properties (as
described in Jolokia's
link:https://jolokia.org/reference/html/agents.html#agents-jvm[reference
manual]). If not set, the `/opt/jolokia/etc/jolokia.properties` file will be
created using the settings as defined in this document, otherwise the rest of
the settings in this document are ignored.
|*_/opt/jolokia/custom.properties_*
|*_AB_JOLOKIA_DISCOVERY_ENABLED_*
|Enable Jolokia discovery. Defaults to *_false_*.
|*_true_*
|*_AB_JOLOKIA_HOST_*
|Host address to bind to. Defaults to *_0.0.0.0_*.
|*_127.0.0.1_*
|*_AB_JOLOKIA_HTTPS_*
|Switch on secure communication with https. By default self-signed server
certificates are generated if no serverCert configuration is given in
*_AB_JOLOKIA_OPTS_*. _NOTE: If the values is set to an empty string, https is
turned `off`. If the value is set to a non empty string, https is turned `on`._
|*_true_*
|*_AB_JOLOKIA_ID_*
|Agent ID to use ($HOSTNAME by default, which is the container id).
|*_openjdk-app-1-xqlsj_*
|*_AB_JOLOKIA_OFF_*
|If set disables activation of Jolokia (i.e. echos an empty value). By default,
Jolokia is enabled. _NOTE: If the values is set to an empty string, https is
turned `off`. If the value is set to a non empty string, https is turned `on`._
|*_true_*
|*_AB_JOLOKIA_OPTS_*
|Additional options to be appended to the agent configuration. They should be
given in the format `"key=value, key=value, …<200b> "`
|*_backlog=20_*
|*_AB_JOLOKIA_PASSWORD_*
|Password for basic authentication. By default authentication is switched off.
|*_mypassword_*
|*_AB_JOLOKIA_PASSWORD_RANDOM_*
|If set, a random value is generated for *_AB_JOLOKIA_PASSWORD_*, and it is
saved in the *_/opt/jolokia/etc/jolokia.pw_* file.
|*_true_*
|*_AB_JOLOKIA_PORT_*
|Port to use (Default: *_8778_*).
|*_5432_*

|*_GC_ADAPTIVE_SIZE_POLICY_WEIGHT_*
|The weighting given to the current Garbage Collection (GC) time versus previous
GC times.
|*_90_*

|Specifies the ratio of the time spent outside the garbage collection (for
example, the time spent for application execution) to the time spent in the
garbage collection.
|*_4_*
|*_JAVA_DIAGNOSTICS_*
|Set this to get some diagnostics information to standard out when things are
happening.
|*_true_*
|*_JAVA_INITIAL_MEM_RATIO_*
|This is used to calculate a default initial heap memory based the maximal
heap memory. The default is 100 which means 100% of the maximal heap is used
for the initial heap size. You can skip this mechanism by setting this value
to 0 in which case no `-Xms` option is added.
|*_100_*
|*_JAVA_MAX_MEM_RATIO_*
|It is used to calculate a default maximal heap memory based on a containers
restriction. If used in a Docker container without any memory constraints for
the container then this option has no effect. If there is a memory constraint
then `-Xmx` is set to a ratio of the container available memory as set here.
The default is 50 which means 50% of the available memory is used as an upper
boundary. You can skip this mechanism by setting this value to 0 in which case
no `-Xmx` option is added.

|Custom hostname for the {project_name} server. *Not set by default*. If not
set, the `request` hostname SPI provider, which uses the request headers to
determine the hostname of the {project_name} server is used. If set, the

=== Known Issues
* There is a known issue with the EAP6 Adapter _HttpServletRequest.logout()_ in which the adapter does not log out from the application, which can create a login loop. The workaround is to call _HttpSession.invalidate();_ after _request.logout()_ to clear the Keycloak token from the session. For more information, see https://issues.redhat.com/browse/KEYCLOAK-2665[KEYCLOAK-2665].
* The SSO logs throw a duplication error if the SSO pod is restarted while backed by a database pod. This error can be safely ignored.
* Setting _adminUrl_ to a "https://..." address in an OpenID Connect client will cause *javax.net.ssl.SSLHandshakeException* exceptions on the SSO server if the default secrets (*sso-app-secret* and *eap-app-secret*) are used. The application server must use either CA-signed certificates or configure the SSO trust store to trust the self-signed certificates.
* If the client route uses a different domain suffix to the SSO service, the client registration script will erroneously configure the client on the SSO side, causing bad redirection.
* The SSO-enabled JBoss EAP image does not properly set the *adminUrl* property during automatic client registration. As a workaround, log in to the SSO console after the application has started and manually modify the client registration *adminUrl* property to *http://_<application-name>_-_<project-name>_._<hostname>_/_<app-context>_*.
