Hi Marek,

How much clients you have in mind?

I guess 100-1000 would be realistic. But more may come later.

 

Theoretically there is no any limit. At least at database level. Fact is that we didn't try to test admin console UI with very big number of clients. Feel free to create JIRA if you're seeing issues.

Thanks. Before doing this, i just want to be sure that i'm on the right path and there are no alternatives. For instance, i've also considered creating a new realm per machine but this won't work either. A user's identity should be global but also have access to selected machine(s). I think that concept can work only within a single realm.

 

Another approach is to design your deployment so the number of clients is not too big. For example when adding new "machine" you can reuse already created clients (not sure if it's the approach which works for you, just a possible hint...)

 
Unfortunately that won't work either. :-(. We need those clients and their respective machines to be in place and operational.

Anyway, thanks for the help Marek!

Hi all,

Is there a limit in the maximum number of clients/applications in single realm supported by keycloak?

I can see that the keycloak admin UI is not built with a big number in mind. For instance, when assigning "Client roles" to a realm user there is a dropdown with all clients/applications in the realm. I guess this shouldn't grow too big to be usuable.

I'm working on a scenario where i need to implement authorization in a system where new machines (and their respective keycloak applications) will be added on the fly. So i'm worying about what will happen if the number starts to grow.

Thanks
