Rocket is an application container engine developed for modern production cloud-native environments. It features a pod-native approach, a pluggable execution environment, and a well-defined surface area that makes it ideal for integration with other systems. The core execution unit of rkt is the pod, a collection of one or more applications executing in a shared context (Rocket's pods are synonymous with the concept in the Kubernetes orchestration system). Rocket allows users to apply different configurations (like isolation parameters) at both pod-level and at the more granular per-application level. Rocket's architecture means that each pod executes directly in the classic Unix process model (i.e. there is no central daemon), in a self-contained, isolated environment. rkt implements a modern, open, standard container format, the App Container (appc) spec, but can also execute other container images, like those created with Docker.

Docker provides an integrated technology suite that enables development and IT operations teams to build, ship, and run distributed applications anywhere. Docker allows you to package an application with all of its dependencies into a standardized unit for software development. Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries, anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.
