Docker uses the resources isolating functionalities of the Linux Kernel, like cgroups and namespaces in order to allow to indipendent containers to coexist, avoiding the installation and maintenance of a virtual machine.

Moreover it's possible to create your own repository starting from a ready image called Registry.
