Re: [keycloak-user] keycloak docker image clustering section is not working as expected

Hello everyone, There a confusing section in the clustering [1] section of the keycloak docker image. The documentation states that: *JGROUPS_DISCOVERY_PROPERTIES - an optional parameter with the discovery protocol properties in the following format: * *PROP1=FOO,PROP2=BAR * I can confirm that this parameter is not optional at all. When I run the image with the JGROUPS_DISCOVERY_PROTOCOL environnement variable set and without the JGROUPS_DISCOVERY_PROPERTIES set (since it's said to be optionnal), the container fails to start with the error message below: *10:50:11,999 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([* * ("subsystem" => "jgroups"),* * ("channel" => "ee")* *]) - failure description: {"WFLYCTL0080: Failed services" => {"org.wildfly.clustering.jgroups.channel.ee <http://org.wildfly.clustering.jgroups.channel.ee>" => "java.lang.IllegalArgumentException: dns_query can not be null or empty* * Caused by: java.lang.IllegalArgumentException: dns_query can not be null or empty"}}* Setting the JGROUPS_DISCOVERY_PROPERTIES environnement variable fix the error. So this is not an optional parameter.
