The Kubernetes generator probably needs updates for Keycloak too.

@qmonmert Do we need to specify the management port in this file or do you think it's OK as-is?

@mraible I am not a specialist of Kubernetes so I don't know

@qmonmert After looking closer, I don't believe it needs to change since port 9000 is the default management port and that shouldn't be used in a production environment, unlike development and npm start.
