Because containers are designed to be ephemeral, we need to set up permanent storage for the database. Smaller than Virtual Machines: Because container images include only the content needed to run an application, saving and sharing is much more efficient with containers than it is with virtual machines (which include entire operating systems) ; Improved performance: Likewise, since you are not running an entirely separate operating system, a container will typically run faster than As result codes in the standard output on the command line.
