My microservice applications (at this time) DO NOT KNOW anything, whether I use a domain mode cluster or, a simple standalone keycloak instanceattached keycloak.json file has ONLY one keycloak instance (<span style="font-size:12pt">MASTER's</span><span style="font-size:12pt"> )</span><span style="font-size:12pt"> "auth-server-url" info ).</span></div><div>Here, I need your help to enlighten me. Is there another approach to handle my problem? It should, otherwise why writing about Domain Mode in Keycloak Release documentation. Unfortunately, I have not found (yet ) detailed info on how to configure a Keycloak Domain Cluster and how to do test simulations with it. I would appreciate any help on this issue.</div><div>Thanks,</div><div>Ioan </div><div> </div><div> </div></div></div><br>______________________________<wbr>_________________<br>
