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

This gist describes the configuration required for Spring reactive WebClient to make a call to an OAuth2 protected resource through OAuth2.0 Client Credentials Grant Type Flow.

Assumption is that the Authorization Server supports OpenId Connect 1.0 specifications.

The view ClusterRole doesn’t actually have permissions for the Cluster level objects like Nodes and Persistent Volume Claims. So we’ll have to create a new RBAC config.

First, we’ll create a new dashboard-viewonly ClusterRole:

---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: dashboard-viewonly
