Today, there is no easy way to configure logging level on smartrouter image.
Would be good if we have the option to just set an env like LOG_LEVEL=debug

and the image is correctly configured, the logging.properties file needs t be created and the system property added:

-Djava.util.logging.config.file=/etc/logging/logging.properties

Today it can be done by creating a config map, example:

handlers= java.util.logging.ConsoleHandler
.level= ALL
java.util.logging.ConsoleHandler.level= DEBUG
java.util.logging.ConsoleHandler.formatter= java.util.logging.SimpleFormatter
org.kie = TRACE

And set the JAVA_OPTS env adding the config-map location., e.g.

-Djava.util.logging.config.file=/etc/logging/logging.properties
