Docker is an open source application container engine, which is based on Go language and complies with Apache2.0 protocol. It allows developers to package their applications and dependencies into a lightweight, portable container that can be published on any popular Linux machine. Virtualization is also possible. The containers are completely sandboked, there is no interface to each other, and more importantly, the performance overhead of the containers is extremely low.
