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.

If you prefer to use JDBC_PING, see @xgp's example gist here: https://gist.github.com/xgp/768eea11f92806b9c83f95902f7f8f80

Please see also my video about Keycloak Clustering: http://www.youtube.com/watch?v=P96VQkBBNxU
NOTE: The video covers JDBC_PING protocol and uses the legacy Keycloak Wildfly distribution!

Keycloak Cluster Configuration (How to) - Legacy Wildfly Distribution!!!

This is a short and simple example on how to build a proper Keycloak cluster, using JDBC_PING as discovery protocol and an NGINX server as reverse proxy.

As this is for legacy Keycloak version (Wildfly based, up until version 17), you can find an example for more current and uptodate versions at this gist here: https://gist.github.com/dasniko/3a57913047af3ca1b6b0a83b294dc1a1
