.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

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:http://www.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_*

|*_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_*

|Password for basic authentication. By default authentication is switched off.
|*_mypassword_*

saved in the *_/opt/jolokia/etc/jolokia.pw_* file.
|*_true_*

|*_AB_JOLOKIA_PORT_*
|Port to use (Default: *_8778_*).

|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.

=== 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.jboss.org/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>_*.
