    Keycloak Cluster Configuration (How to)
This is a short and simple example on how to build a proper Keycloak cluster, using DNS_PING as discovery protocol and an NGINX server as reverse proxy.
To get it working properly, just enable Docker Swarm mode with docker swarm init and just run it as it were a regular Docker Compose deployment.
So, just docker compose up is enough, don't deploy a swarm stack! (This would cause trouble and extra complexity with networking)

Afterwards, you can disable Swarm again with docker swarm leave -f, if needed.

    Keycloak Events Logging CLI commands
The default Keycloak jboss-logging events listener logs the SUCCESS-events on level DEBUG and all ERROR-events on level WARN.
The default logging level of the root logger is INFO, so the SUCCESS-events won't occur in the log output.
To change this and to be able to read all the events in the log output, there are 2 options (choose one of them!):

Change log level of the org.keycloak.events category logger:
