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

Docker Swarm - Managing Configurations

Docker allows storing configurations outside docker images and running containers. This feature, named configs, eliminates the need to use volumes, bind-mount, or environment variables to pass configurations to containers.

The configs have the following characteristics:

• Configs are not encrypted (secrets are encrypted)
• Config values can be strings or binary data
• Config values have maximum size of 500 kB
• Configs are mounted as a file in the container filesystem. The default location is /<config-name> in the container
• Configs can be added or removed from a service at any time
