Configure docker1.0 in RedHat

Docker-encapsulated applications are independent of the operating system, so they can be transplanted between operating systems and run properly. RHEL 7 intends to use docker as efficiently as possible to prevent applications from competing for resources or being confused about which runtime environment to use.

Docker can connect one container to another and rename the Al container to DB. In this way, container A can be used.

From the long-term schedule in the RHEL docker roadmap, this may go beyond the operating system itself and develop into a series of docker containers, which can support deploying a system with minimal overhead. RedHat wants to deploy it in his Fedora Linux release, just as a test of cutting-edge technologies.
