Keycloak Clustering

[Deeps Kiren]

Hi,

      I have one application running using Wildfly and I have configured keycloak for authentication. Now I want to setup a fail over for keycloak instance, ie, I am planning to use 2 keycloak instances for the same wildfly application. If one keycloak is not working, the application should automatically authenticate using the second keycloak instance. Can we use keycloak clustering for this? I am planning for a  Standalone Clustered Mode. Can anyone help me with this, mainly about setting haproxy(setting  X-Forwarded-For and  X-Forwarded-Proto)?  I am planning to use 3 servers, A for haproxy, B for wildfly and one keycloak instance, C for second keycloak instance.  Tried out steps from https://www.keycloak.org/docs/latest/server_installation/#_clustering , but didnt work.

Thanks & Regards,

Deeps.

Hi Thomas,

                 I checked the link, it is given as copy the acme.test*.pem files from the config/stage/dev/tls into the haproxy director, but I couldn't find  acme.test*.pem inside the path https://github.com/thomasdarimont/keycloak-project-example/tree/main/config/stage/dev/tls and I could only find a .gitkeep file in that path. I am new to this, so not sure if I am doing it correctly. Please help.

Thanks in advance,

Deeps
