Hi I am using keycloak1.5.0 and want to cluster it, I made the changes necessary changes to standalone-ha.xml.

I am running the following command: ./standalone.sh --server-config=standalone-ha.xml -b=0.0.0.0

I am getting the below error:

Caused by: java.net.BindException: [UDP] /0.0.0.0 is not a valid address on any local network interface

I changed my keycloak.json as per the documentation for clustering.

Could you help me figure out what is the issue??

If you're saying you can only access it using localhost, then run it with "bin/standalone.sh -b 0.0.0.0" and it'll be bound to all interfaces.

I don't know what you mean that you can't access from outside world, but if you're running a cluster you'll need a load balance in front. Apache, Nginx or even Undertow would do that for you.

You add nodes by just running more nodes on the same subnet and they'll discover themselves.

Hi,

I have a few applications that are using Keycloak 1.5 and I now want to cluster it. I had followed this link (https://docs.jboss.org/keycloak/docs/1.1.0.Beta2/userguide/html/clustering.html) but i am not able to access this server from outside world and I also wanted to know how I can add nodes to my cluster. Could anyone please help me out in this respect.

Thanks.
