I am trying to config Keycloak on Kubernetes with multiple instances (pods) and use database is Postgres.
I have tried with `jboss/keycloak-ha-postgres`. If I use 1 pod, it works fine. But when I scale to 2 or more pods, got the login error:
Login success -> redirect to dashboard -> come back to login page.
It can not keep the login sessions or something else.
Btw, which Operating Mode should I choose in this case? Standalone Clustered Mode or Domain Clustered Mode? And please help me how to handle it.
