[keycloak-user] Multi Tenancy

I was initially under the impression that I can configure realms as tenants and use KeyCloak for applications that are designed for multi tenancy. But now I have discovered that this is not possible, at least not possible to do it on demand. I hope I am wrong and someone can correct me. Basically what I was trying to do was, when someone signs up to my application platform, I was going to create a realm programmatically via the API. Hence the feature request I raised to have a realm level admin https://issues.jboss.org/browse/KEYCLOAK-292 But that means, I will then have to either configure my Wildfly standalone.xml config with the new realm or add the installation json to my war and redeploy it. This is obviously not ideal for a on demand multi tenant application. Maybe using Roles and create unique roles per tenant which hopefully I can do programatically via the API. I think I might be able to get something going like this but it just feels very hacky and not elegant. Is there any other elegant way? Is Keycloak designed for multi tenancy environments?
