When clustering across separate hosts, I had to change the jgroups-udp
socket binding to listen on the public interface (binds to loopback by
default).

When you start the second instance, are you seeing something like this in

If not, then clustering doesn't work properly and the servers doesn't form
a cluster with each other. From the log you sent, there is just startup of
one server, which indicates that clustering may not work.
Maybe multicast doesn't work in your network. Either disable
firewall/selinux/whatever to have multicast working or switch to TCP
JGroups channel instead of UDP. See the Wildfly and JGroups documentation
for more details.
Also I personally use the virtual hosts to test clustering of 2 servers on
same machine (Ie. have virtual servers like kc1:8080 and kc2:8080) . Using
same host but differ just in port number ( host:8080 and host:8081 ) may
causing mess with cookies, so
I am personally not using the setup like this.

I have tried using standalone-ha.xml with shared database. I thought that
would be enough but it seems like it’s not. The problem is
I log into kc1 instance, and subsequent requests are authenticated.
Then I try viewing
host:8080/auth/realms/master/account
Which is also authenticated.
Then I try to view this on kc1 by changing port like:
host:8081/auth/realms/master/account
At this point I expect to see same page. However I get prompted for login
for both kc1 and kc2. I see no logs at this point.
So now I have switched to using keycloak-ha-postgres because it seemed to
me that it comes clustering enabled out of box. So I nearly did exactly
what this page:
https://hub.docker.com/r/jboss/keycloak-ha-postgres/builds/benk6w5cgdmrqo...
told me to so. The only difference that I have done is adding ports (with
–p 8080:8080 to one instance and –p 8081:8080 to the another one) and
adding a new user.
Once I start the I get this log:

However I still have the same issue as above (I get logged out). Also I
don’t get any new logs for the entire log-in, log-out processes.
Am I doing something wrong?
Thanks,
Sarp
