Mirantis Container Runtime (MCR) is a client-server application with these major components:
A server which is a type of long-running program called a daemon process (the dockerd command).
A REST API which specifies interfaces that programs can use to talk to the daemon and instruct it what to do.
A command line interface (CLI) client (the docker command).
MCR can be installed on several Linux distros as well as on Windows.
MCR is derived from the Moby project, an open framework created by Docker Inc. As such, most of the product commands and setup instruction are identical to those for Docker Engine.
