Gatekeeper - Authorise against a list of Keycloak servers

Hi experts here,

I’ve got something in hands that is getting me headaches. I’ve discovered that the client that will use the gatekeeper proxy may login their customers against a different Keycloak server, depending on the shop’s domain the are buying from. i.e. for a customer logged in on UK shop, the Keycloak server used is, while for a customer in France shop the server would be This is something they can’t change because it would affect many other teams, so we have to adapt to it. The problem is that in my gatekeeper configuration I can only add a single discover-url pointing to a single Keycloak server. Is there anyway I can add a list of discovery-url’s to the configuration, or any other config that would help in this case?

Thanks a lot for your time
