That's assuming a old school cluster.

The Keycloak documentation seems to imply that domain mode is

to standalone-ha in clustered environments.
From the server installation docs:
"Running a cluster in standard mode can quickly become aggravating as the
cluster grows in size. Every time you need to make a configuration change,
you have perform it on each node in the cluster. Domain mode solves this
problem by providing a central place to store and publish configuration. It
can be quite complex to set up, but it is worth it in the end."
We have domain working without issue. We are just looking into moving out
deployment of Keycloak servers to docker. I'm working now on extending the
official Docker image to customize it for our environment and configuration.
Thanks again,
