FYI containers aren't their own entity for subscription management purposes. A subscribed host can run as many containers as it wants, the host's subscriptions work inside the containers. (That said I agree that dealing with subscription-manager at all is a lot more annoying than ... not having to do so with RHEL derivatives!)
