Product Description

RKT (pronounced as rock-it) is an application container engine developed for modern production cloud-native environments. In apart of LXC\LXD or OpenVZ container solutions, which were designed to execute "full system containers", RKT as Docker was designed to run individual applications like: web apps, databases, caches and so on.
RKT uses "App Container Images" (ACIs) specified by the App Container Specification (appc) also it can use Docker images.

Architecture

RKT's primary interface is a command-line tool, rkt, which does not require a long running daemon. This architecture allows rkt to be updated in-place without affecting application containers which are currently running. It also means that levels of privilege can be separated out between different operations.
All state in RKT is communicated via the filesystem. Facilities like file-locking are used to ensure co-operation and mutual exclusion between concurrent invocations of the rkt command.
