Docker uses containers as the basic unit for resource segmentation and scheduling, encapsulates the entire software runtime environment, and is a platform designed for developers and system administrators to build, publish and run distributed applications.
Docker implements resource isolation through namespace, resource limitation through cgroups, and efficient file operations through copy-on-write mechanism
