The move will see Mirantis take on all of the products, intellectual property, and customer contracts, and at least some of the employees, of the Docker Enterprise container management service.
Terms of the deal were not disclosed.
Mirantis, known for being an early backer of both Kubernetes and OpenStack, says it will fold Docker Enterprise into its existing container service, offering the two products side-by-side to businesses.
While Mirantis said it will continue to offer support in the near-term for Docker's products, it was less committal in the longer term, with key products such as orchestration tool Docker Swarm only getting two years of planned support.

It seems the plan will be to assimilate Docker Enterprise into its own offerings sooner than later.
