Hi We want to setup keycloak in cluster mode in k8s. I have read the post https://github.com/fit2anything/keycloak-cluster-setup-and-configuration Can you please suggest which option is best from NS_PING , KUBE_PING, and JDBC_PING Also is there a documentation which tells the reason why the option is better. Is there also any other documentation which tells best practices while running the keycloak in cluster mode.
