Where is docker ee?

Hi, I’m a little bit confused, where is a docker EE is? Now I can’t find any information about this product. Is it still available to purchase? I need docker to use on RHEL7 with official support from docker.

Docker Inc. sold Docker EE to Mirantis, which rebranded it to Mirantis Kubernetes Engine. Swarm supports seems still build-in, even though the name doesn’t imply it.
