Summary

Docker is a platform designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs-such as libraries and other dependencies-and ship it all out as one package. The RutOS Docker UI Manager simplifies the management of Docker images and containers.

Note: Docker is additional software that can be installed from the System → Package Manager page.
