Hello! I am coming up with an application that would host multi-tenant containers in Docker on a Kubernetes Cluster. I also need clusters to manage inbound and outbound mail, as well as DNS. I will need all of these clusters to be connected and support multi-domain tenancy on Kubernetes. All this will be controlled by an API. The API will connect to a split front end UI. One of the will be managing users and clients on an administrative level, and the other one will be a user front-end for management and billing.
I just need to consult someone.
