Overview

Dobby is a container management tool, originally developed by Sky and open-sourced to the RDK community. Dobby is a daemon-based program that makes use of the crun runtime and provides a more user-friendly experience for starting/stopping containers, handles container lifecycle management and enhancing the base functionality provided by crun.

...

Plugins are C++ code written against the plugin interface, allowing for operators to easily add additional functionality, or modify existing functionality easily. All the plugins for Dobby can be found in the RDKPlugins directory in the repo here: https://github.com/rdkcentral/Dobby/tree/master/rdkPlugins. Each plugin contains a README file with documentation on its usage. The TestPlugin is designed as a minimal reference plugin that can be used as an example for your own development.

Note there is a directory in the Dobby repo called plugins which containers legacy plugins required for some platforms. These should not be used as a reference for new plugins.

Usage

The core component of Dobby is the DobbyDaemon. This should be started at STB boot and then listens over dbus for commands. The full dbus API of Dobby can be found here: https://github.com/rdkcentral/Dobby/blob/master/protocol/include/DobbyProtocol.h, although it is not recommended to communicate with Dobby manually over dbus. Instead, Dobby provides abstractions over dbus which are discussed later in this document.
