Overview

Downloadable Application Containers (DAC) is a pan-RDK initiative to develop a container solution that allows binary applications to be downloaded and run on STBs without modification. DAC is initially targeting RDK-V set-top boxes but the aim is to extend DAC to suitable RDK-B devices in due course. DAC is a co-operation effort between Comcast, Sky, Liberty Global, Metrological and Consult Red.

• Crun is an alternative implementation of an OCI runtime, this time written in C and optimised for performance and a low memory footprint. It is developed and supported by RedHat and is currently in use by Podman in Fedora, and will be available in RHEL 8.3.
• This is the runtime supported by Dobby and will be used as the default runtime across RDK.
